DEPOSITORY AUG 0 9 2006 University of Illinois AT UftBANACHAMP)UG* This soil survey is a publication of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (formerly the Soil Conservation Service) has leadership for the Federal part of the National Cooperative Soil Survey. Major fieldwork for this soil survey was completed in 1990. Soil names and descriptions were approved in 2002. Unless otherwise indicated, statements in this publication refer to conditions in the survey area in 2002. This survey was made cooperatively by the Natural Resources Conservation Service and the Illinois Agricultural Experiment Station. Financial assistance was provided by the McLean County Board and the Illinois Department of Agriculture. The survey is part of the technical assistance furnished to the McLean County Soil and Water Conservation District. Soil maps in this survey may be copied without permission. Enlargement of these maps, however, could cause misunderstanding of the detail of mapping. If enlarged, maps do not show the small areas of contrasting soils that could have been shown at a larger scale.

It contains predictions of soil behavior for selected land uses. The survey also highlights soil limitations, improvements needed to overcome the limitations, and the impact of selected land uses on the environment. This soil survey is designed for many different users. Farmers, foresters, and agronomists can use it to evaluate the potential of the soil and the management needed for maximum food and fiber production. Planners, community officials, engineers, developers, builders, and home buyers can use the survey to plan land use, select sites for construction, and identify special practices needed to ensure proper performance. Conservationists, teachers, students, and specialists in recreation, wildlife management, waste disposal, and pollution control can use the survey to help them understand, protect, and enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. The information in this report is intended to identify soil properties that are used in making various land use or land treatment decisions. Statements made in this report are intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are shallow to bedrock. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. These and many other soil properties that affect land use are described in this soil survey. The location of each soil is shown on the detailed soil maps. Each soil in the survey area is described. Information on specific uses is given for each soil. Help in using this publication and additional information are available at the local office of the Natural Resources Conservation Service or the Cooperative Extension Service. William J.

United States Department of Agriculture, Natural Resources Conservation Service, in cooperation with the Illinois Agricultural Experiment Station McLean County is in the central part of Illinois (fig. 1). It is bordered by Woodford, Livingston, Ford, Champaign, Piatt, DeWitt, Logan, and Tazewell Counties. It has a total area of 759,700 acres, or about 1,187 square miles. It is the largest county in Illinois. Bloomington is the county seat. This soil survey updates the survey of McLean County published in 1998 (Windhorn, 1998). It provides more information and has larger maps, which show the soils in greater detail. General Nature of the County This section provides general information about the survey area. It describes settlement and development, farming, physiography and drainage, and climate. Settlement and Development The survey area was inhabited as much as 10,000 years ago. Indian mounds are east of Heyworth and along the Mackinaw River in the Evergreen Lake area (Brigham, 1951). The first European families settled in the area in 1822 (Tate, 1972).They settled in wooded areas near streams. The uplands were the first areas cleared for farming. Later, with the help of tile and dredging, the lower areas were drained and converted to agricultural uses. McLean County was established in 1830. It was named for John McLean, the first representative to Congress from the State of Illinois (McLean Centennial Association, 1955). As a result of the Swamp Land Act of 1850, the State of Illinois gave 23,793 acres of the lowest land in the area to McLean County (Hopkins et al., 1915). These lands were to be reclaimed by dredging and tiling. Because no workable plan could be decided on, however, the wetlands were sold. With the proceeds from this sale, the county provided $70,000 for the purchase of land north of Bloomington, where Normal University (Illinois State University) had its beginning. In 2000, the population of the county was 150,433. The population increased 16.5 percent from 1990 to 2000. Most of the population growth has been in the 14 Soil Survey of LEGEND 95B—Southern Wisconsin and Northern Illinois Drift Plain 98—Southern Michigan and Northern Indiana Drift Plain 105—Northern Mississippi Valley Loess Hills 108A and 108B—Illinois and Iowa Deep Loess and Drift 110—Northern Illinois and Indiana Heavy Till Plain 113—Central Claypan Area 114B—Southern Illinois and Indiana Thin Loess and Till Plain 115A, 115B, and 115C—Central Mississippi Valley Wooded Slopes 120A—Kentucky and Indiana Sandstone and Shale Hills and Valleys 131A—Southern Mississippi Valley Alluvium 134—Southern Mississippi Valley Silty Uplands Figure 1.—Location of McLean County and the major land resource areas (MLRAs) in Illinois (USDA, 1981). expanding Bloomington-Normal urban area (U.S. Department of Commerce, 2002). Transportation systems in the county are well developed. They include five State highways, four U.S. highways, two interstate highways, several railroad lines, one municipal airport, and numerous paved county roads. Farming Farming is among the primary enterprises in the county. Corn and soybeans are the main crops. Grasses and legumes and winter wheat are also grown. Some of the farms raise livestock. Many of the animals are raised in confinement operations. In 1982, the county had 2,126 farms, which made up 745,113 acres, or about 98 percent of the total land area (U.S. Department of Commerce, 1983). The average farm size was 350 acres, or about 50 acres larger than the average farm size for the State of Illinois. Cropland made up 701,075 acres. Of this total, 385,729 acres was used for corn and 287,205 acres for soybeans. The rest of the acreage was used for small grain or for pasture and hay. The number of farms in McLean County dropped from 1,906 in 1987 to 1,475 in 1997. The farmland acreage dropped from 740,964 in 1987 to 696,575 acres in 1997. During this same time period, the acreage of corn increased from 277,851 to 333,205 acres, the acreage of soybeans increased from 287,083 to 312,613 acres, and the acreage of wheat increased from 96,969 to 122,233 acres. The total acreage of woodland was 7,803 in 1997. Of this acreage, 1,741 acres was pastured woodland (USDA, 1997). In 1982, the county produced about 24,000 head of cattle and calves and sold about 134,000 hogs and pigs (U.S. Department of Commerce, 1983). In 1997, McLean County, Illinois 15 the county sold 9,536 head of cattle and calves and sold about 150,790 hogs and pigs (USDA, 1997). Physiography and Drainage McLean County is mainly on a loess-covered till plain characterized by numerous terminal glacial moraines cutting diagonally across the county from northwest to southeast. Glacial ice, running water, and windblown deposits have all contributed to the landforms in the county. In general, nearly all of the ridges and knobs in the county have a glacial origin. These areas were then modified by the wearing down of hills and knobs and the filling in of lower areas with outwash sediments. Finally, a blanket of loess, which tends to smooth out landscape features, covered the entire landscape. The Bloomington Moraine is one of the most prominent landform features in the county, especially in the eastern and northwestern parts. This moraine cuts through the center of the county. South of the moraine the landscape is mainly nearly level to sloping, except along the major streams, such as Kickapoo Creek and Sugar Creek. In these areas stream dissection resulted in more varied landscapes. In the northeastern part of the county, north of the moraine, the landscape is primarily gently sloping and sloping. In the extreme northwestern part of the county, the landscape is gently sloping to very steep. One of the lowest points in the county is in the southwestern part where Sugar Creek flows out of the county. The elevation at this location is about 600 feet above sea level. One of the highest points is in the area due west of Moraine View State Park. This area is on the Bloomington Moraine and is at an elevation of about 926 feet above sea level (fig. 2). In general, all surface water in McLean County eventually empties into the Illinois River. Water south of the Bloomington Moraine flows southwest in creeks, such as Kickapoo Creek, Sugar Creek, and Salt Creek. Water in the eastern part of the county flows east in the Sangamon River before emptying into the Illinois River. Water north of the Bloomington Moraine flows northwest in the Mackinaw River. Water in the extreme northeastern part of the county flows north toward the Vermilion River. The county has about 2,792 acres of impounded water. Most of this water is in Lake Bloomington, Dawson Lake, Evergreen Lake, and Spin Lake. The rest is in smaller, privately owned ponds.

The lowest temperature on record, which occurred at Chenoa on December 22, 1989, was -26 degrees. In summer, the average temperature is 72.9 degrees and the average daily maximum temperature is 84.2 degrees. The highest temperature, which occurred at Chenoa on August 17, 1988, was 103 degrees. Growing degree days are shown in table 1. They are equivalent to “heat units.” During the month, growing degree days accumulate by the amount that the average temperature each day exceeds a base temperature (50 degrees F).The normal monthly accumulation is used to schedule single or successive plantings of a crop between the last freeze in spring and the first freeze in fall. The average annual total precipitation is 34.52 inches. Of this, 20.78 inches, or about 60 percent, usually falls in April through September. The growing season for most crops falls within this period. The heaviest 1-day rainfall on record was 8.20 inches at Chenoa on July 9, 1951. Thunderstorms occur on about 48 days each year, and most occur between May and August. The average seasonal snowfall is 23.0 inches. The greatest snow depth at any one time during the period of record was 20 inches on March 11,1960. On the average, 34 days of the year have at least 1 inch of snow on the ground. The heaviest 1-day snowfall on record was 12.0 inches on December 19, 1973. The average relative humidity in midafternoon is about 60 percent. Humidity is higher at night, and the average at dawn is about 83 percent. The sun shines 67 percent of the time possible in summer and 46 percent in winter. The prevailing wind is from the south. Average windspeed is highest, 11 to 12 miles per hour, from November to April. How This Survey Was Made This survey was made to provide information about the soils and miscellaneous areas in the county. The information includes a description of the soils and miscellaneous areas and their location and a discussion of their suitability, limitations, and management for specified uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage and the kinds of crops and native plants. To study the soil profile, which is the sequence of natural layers, or horizons in a soil, soil scientists use soil probes or spades. The profile extends from the surface down into the unconsolidated material in which the soil formed. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. The soils and miscellaneous areas in the county occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the county. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept or model of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landform. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil- vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior McLean County, Illinois 17 of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. The soil survey information in this report is based on a review of field notes, laboratory data, and other data collected during the previous survey of McLean County (Windhorn, 1998). In addition, data from other soil surveys within Major Land Resource Areas 108A, 110, and 115C were reviewed and some resampling of selected soils to greater depths was conducted. The review of new and existing data over a wider area improves consistency in the identification, classification, and interpretations of soils on similar landscapes. Digital orthophotographs used in this survey were taken early in spring between 1993 and 1995. Soil scientists studied U.S. Geological Survey topographic maps enlarged to a scale of 1:12,000 and geology maps to relate land and image features. Specific soil boundaries were drawn on the orthophotographs. Soil boundary lines were adjusted so that they would better coincide with the topographic map contour lines and tonal patterns on the orthophotographs. 19 Formation and Classification of the Soils This section relates the soils in the survey area to the major factors of soil formation and describes the system of soil classification. Formation of the Soils Soil forms through processes that act on deposited or accumulated geologic materials. The characteristics of the soil are determined by the physical and mineralogical composition of parent material; the climate under which the soil formed; the plant and animal life on and in the soil; the relief, or lay of the land; and the length of time that the forces of soil formation have acted on the parent material (Jenny, 1941). The factors of soil formation are so closely interrelated in their effects on the soil that few generalizations can be made regarding the effects of any one factor unless the effects of the other factors are known. Many of the processes of soil formation are unknown. The parent material affects the kind of soil profile that forms. Climate and plant and animal life are the active factors of soil formation. They act directly on the parent material, either in place or after it has been relocated by water, glaciers, or wind, and slowly change it into a natural body that has genetically related layers, or horizons. Relief can modify the effects of climate and plant and animal life. Finally, time is needed for transformation of the parent material into a soil profile that has clearly differentiated horizons. Parent Material Parent materials are determined by the geology of an area. They control the chemical and mineralogical composition of the soil at the beginning of soil formation. Weathering and biological activities gradually change the composition of the soil as it develops. Parent material includes all organic and inorganic material at the earth’s surface. In places old weathered bedrock material and old soil material become parent material for the continuing soil development at the land surface (Brady, 1984; Broderson, 1994; Press and Siever, 1985). The parent materials of the soils in McLean County are mainly associated directly with glaciers, meltwater, and wind of the Wisconsinan Glacial Stage and the Holocene (Willman and Frye, 1970). Although the parent materials are glacial in origin, their properties vary greatly, depending on the method of deposition. The dominant parent materials in McLean County are loess, glacial till, glacial outwash (including sand and gravel), alluvium, and colluvium. Loess blankets the uplands of McLean County. It is silty material deposited by winds that carried it from major stream valleys and outwash plains. It consists of very uniform, calcareous, silt-sized particles. The major sources of the loess in the county are the valley of the Illinois River and many smaller stream valleys. Loess was initially deposited as sediments in rivers swollen with glacial meltwater. As the rivers dried up, these sediments were exposed. The predominantly westerly winds picked up the loess and transported it many miles. The loess covered the exposed glacial till and outwash with a layer that tended to thin with increasing distance from the source. Some soils in the county formed entirely in loess. In areas where the deposits are thinner, the soils formed in loess and in the underlying till or outwash. Osco and Ipava soils formed entirely in loess. Saybrook and Russell soils formed in loess and the underlying till. Glacial till is material laid down directly by active glaciers. It is a mixture of materials that were picked up by the ice as it moved over the land. The size of particles ranges from clay to occasional boulders. The kinds of till exposed in McLean County are from distant as well as local sources. The rocks and minerals in the till from distant sources are granite, quartzite, diorite, galena, and pyrite. Shale and limestone indicate local sources.The small pebbles in glacial till generally have distinct edges and corners, indicating that they have not been subject to intense water action. The glacial till in McLean County was deposited during the Wisconsinan Stage. Numerous recessional end moraines are evident in the county. The most notable of these is the Bloomington Moraine, which extends from Danvers Township, in the northwest part of the county, through Bloomington-Normal, and then to Cheneys Grove 20 Soil Survey of Township, at the edge of the county line. The moraines are generally oriented from northwest to southeast, except for the Champaign Moraine, which extends north and south in the Bellflower area. The glacial till is generally loam, clay loam, or silt loam and is calcareous. It ranges from light pink to dark gray, depending on the source area of the till. Soils that formed in this parent material generally are gently sloping to very steep and are on ridgetops and side slopes. La Rose and Strawn are examples of soils that formed entirely in till. Many soils in Mclean County formed in loess and the underlying till. Dana and Saybrook soils are examples. Ground moraines cover much of the county. They are generally flat to gently rolling plains and are made up of till material similar to that on the recessional and end moraines. Catlin and Flanagan soils are on ground moraines. The till in the northern part of the county typically has more clay than the previously mentioned till. Ashkum, Chenoa, and Varna are examples of soils that formed in till in this part of the county. Throughout McLean County and east-central Illinois, the upper part of the till on ground moraines and below end and recessional moraines appears to be water worked and unconsolidated. As much as 2 feet of this washy till or ablation till overlies the more compacted till. It is sometimes correlated as outwash because of its interpretive properties. Glacial outwash, including sand and gravel, is deposited by running water, either from melting glaciers or from streams. These deposits can occur in front of the margins of glacial moraines and in more concentrated areas in channels of the major stream valleys. These sediments vary greatly in particle size and composition from place to place. The size of deposited outwash particles varies, depending on the speed of the stream that carried them. The coarser particles were deposited first, and the finer particles were carried a greater distance by more slowly moving water. Penfield soils formed in outwash. Outwash deposits generally consist of strata of sandy loam, loam, and silt loam. In some areas where meltwater flowed rapidly, the deposits are coarser textured and gravel and coarse sand are more dominant. Examples of soils that formed in coarse textured outwash are Fox, Warsaw, and Lorenzo soils. The outwash in McLean County is typically calcareous and has a low to moderate ability to hold water and nutrients available for plants. Some of the coarser deposits of outwash along the major streams are commercial sources of sand and gravel (fig. 3). Alluvium is material deposited largely during periods of flooding. This material is generally silty because its source area is the loess-covered glacial till uplands. Alluvial areas occur along major streams throughout the county and also extend back into some upland drainageways. Stream alluvium can be eroded from anywhere upstream within the watershed. The streambanks in McLean County often expose the alluvial history of the stream. Occasional or frequent flooding is still likely in most alluvial areas. Examples of alluvial soils are Lawson, Huntsville, and Sawmill soils. Aetna and Radford soils are common in areas where recent flooding has buried darker soil horizons. Colluvium is local alluvium that has moved downslope. Peotone soils, which are in depressions, formed in colluvium, and Ashkum soils, which are on toeslopes, formed in colluvium and the underlying till. Climate Climate is important in the formation of soils. The county has a temperate, humid, continental climate that is essentially uniform throughout the county. Climate differences are too small to have caused any obvious differences in the soils locally. Climate affects soil formation through its effects on weathering, plant and animal life, and erosion. Under the present climate, soil moisture fluctuates with precipitation and seasonal changes that vary from year to year (Brady, 1984; Broderson, 1994; Press and Siever, 1985; Windhorn, 1998). Water from rains and melting snow seeps slowly downward through the soil and causes physical and chemical changes. As the water moves through the profile, clay is transported from the surface layer to the subsoil, where it accumulates. Ipava soils are examples of soils in which this process has taken place. The water also dissolves minerals and moves them downward through the soil. This leaching process has removed calcium carbonate (free lime) from the upper layers of most of the soils in McLean County. Heavy, untimely rains are harmful and destructive when they fall on soils that are exposed by farming activities. If the soil is partially frozen, early spring rains can cause extensive erosion because the infiltration of water is restricted early in spring. Soil temperature affects soil formation. If the soil is frozen, rainfall runs off the soil and thus does not facilitate soil formation. Many of the processes of soil formation are halted or proceed at a slower rate when the soil is frozen. Climate influences the kind and extent of plant and animal life. The climate in McLean County has favored tall grass prairie and deciduous hardwood forests. It has also favored animal life, which decomposes dead plants and animals and incorporates them into the soil. McLean County, Illinois 21 Figure 3.—Outwash that is being mined for gravel in an area of Warsaw loam, 0 to 2 percent slopes. Plant and Animal Life Soils are greatly affected by the type of vegetation under which they formed. One of the most easily recognized examples of the effect of vegetation on soil formation is the difference between prairie soils and forest soils. The chief contribution of vegetation and biological processes is the addition of organic matter and nitrogen to the soil. The kind of organic material in the soil depends primarily on the kind of native plants that grew on the soil. The remains of these plants accumulate in or on the surface, decay, and eventually become organic matter, or humus. The roots of the plants provide channels for the downward movement of water through the soil and also add organic matter as they decay. The native vegetation in McLean County consisted mainly of tall prairie grasses and deciduous hardwood trees. At the time of early settlement, most of the survey area supported prairie grasses. These grasses have many fine, fibrous roots that add large amounts of organic matter to the soil as they die and decay, especially where they are concentrated near the surface. Decomposition of plant materials produces humus-rich soils that have a high level of fertility and a high water-holding capacity. Excess wetness in soils slows the rate of decomposition, and the organic matter accumulates over time. Soils that formed under prairie vegetation have a thick, black or dark brown surface layer. The prairie soils in McLean County are generally on the broad upland divides between streams (fig. 4). The thickness of the surface layer varies greatly, depending on landscape position. Soils that formed on ridgetops and shoulders, such as Dana and Saybrook soils, have a thinner dark surface layer than soils in nearly level areas, such as Ipava, Flanagan, Muscatune, Raub, and Lisbon soils. Some soils in depressions have a black surface layer that is more than 24 inches thick. Peotone soils are an example. About 6 percent of the county supported timber vegetation at the time of early settlement. The deciduous hardwood forests contributed organic matter to the soil mainly in the form of leaf litter. The 22 Soil Survey of Figure 4.—Drummer and Flanagan soils on broad upland divides between streams. soils that formed under trees have a thinner, lighter colored surface layer and subsurface layer than the soils that formed under grasses. Organic matter in forests accumulates at the surface, and the humus that is produced is more acidic than grassland humus. These acids percolate into the soil and promote the break down of minerals in the soil. This acidification process increases the rate of leaching and translocation, which lower fertility and causes clay¬ sized particles to accumulate in lower layers. Where this process is active for a long time, it produces an obvious eluvial horizon that has a bleached or ashy appearance. This layer can form a crust when dry. The crust can impede the downward movement of water. The light colored subsurface layer and the lower content of organic matter in the surface layer result in the characteristic white appearance of the soils that formed in wooded areas. In general, these soils are on narrow upland divides between streams or on the side slopes bordering streams. Keomah, Rozetta, Mayville, Birkbeck, and Sabina soils formed under timber vegetation. About 4 percent of the county supported mixed prairie and timber vegetation at the time of early settlement. Atterberry and Kaneville soils formed under mixed vegetation in the uplands. Most of the soils on flood plains formed under a mixture of trees and grasses, especially in the larger valleys. Most of these soils are dark because of a high content of organic matter, but the dark colors are related more to the color of the sediments deposited than to the native vegetation. Lawson, Huntsville, and Sawmill are examples of soils that formed on flood plains. Micro-organisms, earthworms, insects, and large burrowing animals that live in or on the soil have affected soil formation. Bacteria and fungi help to break down and decompose dead plants and animals and change them into humus. Burrowing animals, such as earthworms, crayfish, cicadas, mice, and ground squirrels, help to incorporate the humus into the soil. Humus is very important in the formation of soil structure. It also affects the tilth of the soil. In McLean County, evidence of the burrowing activities of these insects and animals is most noticeable in wet soils, such as Peotone, Sable, Drummer, Hartsburg, and Harpster soils. In some areas of these soils, crayfish and earthworms have constructed “chimneys” of soil material on the surface as tunnels were formed. Evidence of human activity in the survey area dates back to approximately 10,000 years before present. This period coincides with the ice retreat and meltwaters of the last major glaciation that covered McLean County, Illinois 23 northeastern Illinois. Humans did not have a significant effect on the soils or the environment until the arrival of European settlers in North America. During the late 1800s and early 1900s, areas of land were cleared with the moldboard plow for pasture and row crops. The result of these activities significantly increased the extent of erosion and decreased the content of organic matter and biological activity in the soil. Many soils lost valuable topsoil. The lighter colored subsoil of these soils was exposed. In places the subsoil was clayey and difficult to work (Brady, 1984; Windhorn, 1998). Relief Relief, or local changes in elevation, has had a marked influence on the soils in McLean County through its effect on runoff, water infiltration, erosion, and natural soil drainage. Slopes in McLean County range from 0 to 50 percent. The landscape is changing slowly but constantly. Initially, many of the landforms and features could be attributed directly to their mode of deposition—that is, the glaciers or the glacial meltwater. Once the glaciers began to recede, depositional and erosional forces started shaping the landscape, creating the landforms that are evident today. In general, map unit boundaries follow landform and landform component boundaries. The landform shape and size play a role in soil formation. The shape and slope of a landform affect drainage. Level areas or depressions generally are characterized by poor natural drainage, forcing water to pond or percolate into the soil (fig. 5). The soils in depressions in McLean County have a higher content of clay in the surface layer and are ponded. The soils on gentle slopes, such as Ipava and Camden soils, are characterized by more water infiltration, less erosion, and stronger, deeper development than the soils on steeper slopes or soils that are wet and ponded. Rounded summits and shoulder slopes are characterized by better drainage, causing more water to flow downhill. Increased runoff increases the extent of erosion and further shapes the landscape. The soils on the steeper slopes commonly are more eroded and less well developed than the less sloping soils. Figure 5.—Water standing in a ponded area of Drummer silty clay loam, 0 to 2 percent slopes. 24 Soil Survey of Hennepin and Strawn soils on steep slopes along stream valleys and are examples of soils with little or shallow development (Herzog, 1994; Windhorn, 1998). Time The amount of time that material has been exposed to the soil-forming processes and the rate of development determine the stage of development. The soil-forming cycle is associated with geologic events, such as glaciation and flooding, that lead to deposition, weathering, and erosion cycles. The age of material can be determined by correlation to similar materials of known age or by some other dating process. Artifacts of known age as well as fossil pollen found in the soil can give clues to the approximate time of formation. Radiocarbon dating of organic material is commonly used to determine the ages of materials up to about 50,000 years old. Soil development progresses with time. The changes with time are expressed in morphological features and are commonly interpreted as the result of time. Changes in color and soil structure are the most apparent features. The stronger the features are expressed, the older the soil is likely to be. However, even though a parent material may have been formed at one time, the soils at different locations that have different environmental histories develop at different rates and show differences in soil structure, color, and other properties. In general, more weathering produces a more mature soil. Even though materials may be deposited at the same time, they may have developed at different rates. The youngest soils are weakly developed and are in areas where deposition of parent material has occurred periodically during recent flooding along streams. Lawson soils show weak profile development because they are on flood plains that frequently receive alluvial sediments. Other young soils are along footslopes in colluvial areas. These soils have characteristic layering that is related to the different events of sedimentation. The stage of development in these soils is related to the age of the parent material in which the soils formed and the time of the deposition. Birkbeck soils show more evidence of horizonation because the loess and till parent materials have been in place a much longer time than the sediments of alluvial soils. Nearly all the exposed soils in McLean County are less than 12,600 years old. This age coincides with the cessation of significant loess accumulation (Follmer, 1979; Johnson and Follmer, 1989). The rate of the development of soils depends on parent material, biological activity, climate, and relief. All soil profiles reveal evidence of their stage of development, but appearance does not always indicate the age of the soil in terms of years. Classification of the Soils The system of soil classification used by the National Cooperative Soil Survey has six categories (Soil Survey Staff, 1998 and 1999). Beginning with the broadest, these categories are the order, suborder, great group, subgroup, family, and series. Classification is based on soil properties observed in the field or inferred from those observations or from laboratory measurements. Table 4 shows the classification of the soils in the survey area. The categories are defined in the following paragraphs. ORDER. Twelve soil orders are recognized. The differences among orders reflect the dominant soil¬ forming processes and the degree of soil formation. Each order is identified by a word ending in sol. An example is Alfisol. SUBORDER. Each order is divided into suborders primarily on the basis of properties that influence soil genesis and are important to plant growth or properties that reflect the most important variables within the orders. The last syllable in the name of a suborder indicates the order. An example is Udalf (Ud, meaning humid, plus alf, from Alfisol). GREAT GROUP Each suborder is divided into great groups on the basis of close similarities in kind, arrangement, and degree of development of pedogenic horizons; soil moisture and temperature regimes; type of saturation; and base status. Each great group is identified by the name of a suborder and by a prefix that indicates a property of the soil. An example is Hapludalfs ( Hapl , meaning minimal horizonation, plus udalf, the suborder of the Alfisols that has a udic moisture regime). SUBGROUP. Each great group has a typic subgroup. Other subgroups are intergrades or extragrades. The typic subgroup is the central concept of the great group; it is not necessarily the most extensive. Intergrades are transitions to other orders, suborders, or great groups. Extragrades have some properties that are not representative of the great group but do not indicate transitions to any other taxonomic class. Each subgroup is identified by one or more adjectives preceding the name of the great group. The adjective Typic identifies the subgroup that typifies the great group. An example is Typic Hapludalfs. McLean County, Illinois 25 FAMILY. Families are established within a subgroup on the basis of physical and chemical properties and other characteristics that affect management. Generally, the properties are those of horizons below plow depth where there is much biological activity. Among the properties and characteristics considered are particle-size class, mineralogy class, cation-exchange activity class, soil temperature regime, soil depth, and reaction class. A family name consists of the name of a subgroup preceded by terms that indicate soil properties. An example is fine-loamy, mixed, active, mesicTypic Hapludalfs. SERIES. The series consists of soils within a family that have horizons similar in color, texture, structure, reaction, consistence, mineral and chemical composition, and arrangement in the profile. 27 Soil Series and Detailed Soil Map Units In this section each soil series recognized in the survey area is described. Each series description is followed by detailed descriptions of the associated detailed soil map units. Characteristics of the soil and the material in which it formed are identified for each soil series. A pedon, a small three-dimensional area of soil, that is typical of the series in the survey area is described. In some instances the typical pedon for the series is located outside McLean County. The selection of typical pedons is based on the range of characteristics of the series as it occurs throughout a particular major land resource area (MLRA). The Varna series, for example, is common in MLRA 110 (Northern Illinois and Indiana Heavy Till Plain), which includes most of northeastern Illinois. The typical pedon for the Varna series is located in Ford County, Illinois. The soil properties of this pedon are representative of the Varna soils that occur not only in Ford County but also in McLean County and other counties within MLRA 110 . The detailed description of each soil horizon follows standards in the “Soil Survey Manual” (Soil Survey Division Staff, 1993). Many of the technical terms used in the descriptions are defined in “Soil Taxonomy” (Soil Survey Staff, 1999) and in “Keys to Soil Taxonomy” (Soil Survey Staff, 1998). Unless otherwise stated, colors in the descriptions are for moist soil. Following the pedon description is the range of important characteristics of the soils in the series. The map units on the detailed soil maps in this survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions in this section, along with the maps, can be used to determine the suitability and potential of a unit for specific uses. They also can be used to plan the management needed for those uses. More information about each map unit is given under the headings “Use and Management of the Soils” and “Soil Properties.” A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. Miscellaneous surface features that are too small or narrow to be mapped at the scale used in the survey are identified by a special symbol. “Gravelly spot” is an example of a miscellaneous surface feature that is too small (less than 3 acres) to be mapped. The contrasting components are mentioned in the map unit descriptions. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The 28 Soil Survey of delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives the principal hazards and limitations affecting specific uses. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer or of the underlying layers, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer or of the underlying layers. They also can differ in slope, stoniness, salinity, wetness, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. The name of a soil phase commonly indicates a feature that affects use or management. For example, Birkbeck silt loam, 2 to 5 percent slopes, eroded, is a phase of the Birkbeck series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes or undifferentiated groups. A complex consists of two or more soils in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils are somewhat similar in all areas. Catlin-Saybrook silt loams, 2 to 5 percent slopes, is an example. An undifferentiated group is made up of two or more soils that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils in a mapped area are not uniform. An area can be made up of only one of the major soils, or it can be made up of all of them. An example of an undifferentiated group in this survey area is Miami and Hennepin soils, 18 to 35 percent slopes. This survey includes miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Pits, gravel, is an example. Table 5 gives the acreage and proportionate extent of each map unit. Other tables give properties of the soils and the limitations, capabilities, and potentials for many uses. The Glossary defines many of the terms used in describing the soils or miscellaneous areas.

It can be used to adjust land uses to the limitations and potentials of natural resources and the environment. Also, it can help to prevent soil-related failures in land uses. In preparing a soil survey, soil scientists, conservationists, engineers, and others collect extensive field data about the nature and behavioral characteristics of the soils. They collect data on erosion, droughtiness, flooding, and other factors that affect various soil uses and management. Field experience and collected data on soil properties and performance are used as a basis in predicting soil behavior. Information in this section can be used to plan the use and management of soils for crops and pasture; forestland; as sites for buildings, sanitary facilities, highways and other transportation systems, and parks and other recreational facilities; for agricultural waste management; and as wildlife habitat. It can be used to identify the potentials and limitations of each soil for specific land uses and to help prevent construction failures caused by unfavorable soil properties. Planners and others using soil survey information can evaluate the effect of specific land uses on productivity and on the environment in all or part of the survey area. The survey can help planners to maintain or create a land use pattern in harmony with the natural soil. Contractors can use this survey to locate sources of sand, gravel, roadfill, topsoil, and reclamation material. They can use it to identify areas where bedrock, wetness, or very firm soil layers can cause difficulty in excavation. Health officials, highway officials, engineers, and others may also find this survey useful. The survey can help them plan the safe disposal of wastes and locate sites for pavements, sidewalks, campgrounds, playgrounds, lawns, and trees and shrubs. Interpretive Ratings The interpretive tables in this survey rate the soils in the survey area for various uses. Many of the tables identify the limitations that affect specified uses and indicate the severity of those limitations. The ratings in these tables are both verbal and numerical. Rating Class Terms Rating classes are expressed in the tables in terms that indicate the extent to which the soils are limited by all of the soil features that affect a specified use or in terms that indicate the suitability of the soils for the use. Thus, the tables may show limitation classes or suitability classes. Terms for the limitation classes are not limited, somewhat limited, and very limited. The suitability ratings are expressed as well suited, moderately suited, poorly suited, and unsuited or as good, fair, and poor. Numerical Ratings Numerical ratings in the tables indicate the relative severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.00 to 1.00. They indicate gradations between the point at which a soil feature has the greatest negative impact on the use and the point at which the soil feature is not a limitation. The limitations appear in order from the most limiting to the least limiting. Thus, if more than one limitation is identified, the most severe limitation is listed first and the least severe one is listed last. Crops and Pasture General management needed for cropland and for hay or pasture is suggested in this section. The estimated yields of the main crops and pasture plants are listed, the system of land capability classification used by the Natural Resources Conservation Service is explained, and prime farmland is described. Planners of management systems for individual fields or farms should consider the detailed information given in the description of each soil under the heading “Soil Series and Detailed Soil Map Units.” Specific information can be obtained from the local office of the Natural Resources Conservation Service or the Cooperative Extension Service. 144 Soil Survey of In 1997, approximately 665,894 acres in McLean County was used as cropland. Of this acreage, 333,205 acres was used for corn for grain or seed, 312,613 acres was used for soybeans, 1,844 acres was used for wheat, 881 acres was used for oats, and 5,919 acres was used for hay. The remaining acreage was used for pasture or alternative or specialty crops (USDA, 1997). The major row crops are corn and soybeans. The major small grain crops are wheat and oats. Forage crops include smooth brome, orchardgrass, alfalfa, and red clover. Specialty crops include maple syrup, fruits, vegetables, sunflowers, trees, and nursery crops. The soils in McLean County have excellent potential for continued crop production, particularly if the latest crop production technology is applied. This soil survey can be used as a guide in applying the latest technology. Measures that control erosion and reduce wetness are needed on much of the cropland and pasture in McLean County. Loss of the surface layer through erosion is damaging in two ways. First, productivity is reduced as the surface layer is lost and part of the subsoil is incorporated into the plow layer. The subsoil generally has fewer plant nutrients, a lower content of organic matter, and a higher content of clay than the surface layer. As the content of organic matter in the tilled layer decreases and the content of clay increases, soil tilth deteriorates. Deterioration of tilth increases the likelihood that a crust will form on the surface and reduces the rate of water infiltration. The higher content of clay increases the likelihood that the surface layer will become cloddy when tilled, especially if tilled when wet. When the surface layer is cloddy, preparing a seedbed is very difficult. The soils tend to puddle after hard rains and crust as they dry. The crust increases the runoff rate. Loss of the surface layer is especially damaging on soils having a subsoil that is unfavorable for plant growth, such as Varna soils; on soils that tend to be droughty, such as Lorenzo soils; and on soils that are moderately eroded, such as Strawn soils. Second, erosion on farmland results in the sedimentation and pollution of streams. Controlling erosion minimizes this pollution and improves the quality of water for municipal and recreational uses and for fish and wildlife. Erosion-control measures provide a protective plant cover, increase the rate of water infiltration, and reduce the runoff rate. A cropping system that keeps plants on the surface for extended periods reduces the hazard of erosion and preserves the productive capacity of the soils. Including forage crops of grasses and legumes in the cropping sequence helps to control erosion in the more sloping areas. It also provides nitrogen and improves tilth for the next crop. Generally, a combination of several practices is needed to control erosion. Conservation tillage, including chisel tillage and no-till farming, is common in McLean County. Contour stripcropping, contour farming, conservation cropping systems, crop residue management, terraces, diversions, buffer strips, riparian areas, and grassed waterways also help to prevent excessive soil loss. Most of the cropland in McLean County can be protected from erosion by a conservation tillage system. Conservation tillage includes any noninversion tillage practice that keeps a protective amount of crop residue on the surface throughout the year. The crop residue increases the rate of water infiltration by improving tilth. It also protects the surface from the beating action of raindrops, helps to prevent surface crusting, and generally provides a more friable seedbed for good germination (fig. 6). Chisel tillage is a common form of conservation tillage used in McLean County. When this system is applied, crop residue covers 20 to 60 percent of the surface. The extent of the coverage depends on the type of chisel plow used, the speed with which the equipment moves through the field, and the kind of crop planted. Chisel tillage often follows stalk chopping in the fall, but it can also be used immediately prior to planting in the spring. No-till farming is being used on an increasing acreage in the county. When this system is applied, a grain crop is planted directly in a cover crop, sod, or Figure 6.—Corn residue on a Catlin soil.The residue will improve tilth and the nutrient-holding capacity of the soil. McLean County, Illinois 145 Figure 7.—No-till wheat planted into corn stubble on the well drained Plano silt loam, 2 to 5 percent slopes. the crop residue of the previous year (fig. 7). A special planter that disturbs only the row area is used. Herbicides are used to control competing vegetation. The nearly complete ground cover protects the soil from the impact of raindrops and helps to control the erosion caused by runoff. Terraces reduce the hazard of erosion by shortening the slopes and by controlling runoff. If a tile outlet terrace is used, the water that collects behind the terrace is removed by tile at a slow, controlled rate. Grassed waterways reduce the hazard of erosion by providing a stable channel for water runoff on sloping land (fig. 8). Conservation buffer strips and riparian areas can help to maintain stream channels and slow runoff. A stream channel without trees will slump, whereas a protected riparian area helps to maintain the stream channel (fig. 9). Contour farming involves conducting tillage or other fieldwork along the contour rather than up and down the slope. This practice helps to control erosion because it results in the formation of small ridges perpendicular to the slope of the land. The ridges greatly reduce the velocity of the water moving down the hills. Stripcropping, although not used widely in McLean County, is an effective erosion-control measure if used in combination with other measures. It involves alternating rows or strips of one crop with rows of another crop that has a different rate of maturity and a different canopy cover. The rows are planted on the contour. The plant cover that results from this practice helps to control erosion by protecting the surface from the impact of raindrops. Erosion-control management through tillage and cropping systems is effective alone or in combination on most of the farmland in the county. The combination used and its effectiveness depend on soil characteristics and topography. Information about the design of erosion-control practices for each kind of soil is provided in the Field Office Technical Guide, which is available in the local office of the Natural Resources Conservation Service. Drainage systems consist of subsurface tile drains, surface inlets, open drainage ditches, or a combination of these. Drainage systems have been installed in most areas of poorly drained and somewhat poorly drained soils in the county (fig. 10). As a result, these soils are adequately drained for the crops commonly grown in the county. Some areas of poorly drained soils require surface tile inlets or shallow surface ditches to remove ponded water. Some areas of somewhat poorly drained soils are wet long enough that in some years productivity is reduced unless a drainage system is installed. Management of drainage in conformance with wetland regulations may require special permits and extra planning. The design of surface and subsurface drainage systems varies with the kind of soil and the availability of drainage outlets. In some areas of poorly drained soils in depressions, a combination of surface drains and tile drains is needed. The tile should be more closely spaced in the more slowly permeable soils than in the more rapidly permeable soils. Manipulating drainage can allow the producer to conserve moisture, manage weeds and insects, and limit leaching of nutrients and chemicals. Further information about drainage systems is provided in the Field Office Technical Guide, which is available in local offices of the Natural Resources Conservation Service. 146 Soil Survey of Figure 8.—A grassed waterway in an area of Saybrook silt loam, 5 to 10 percent slopes, eroded. Limitations and Hazards Affecting Cropland The main concerns in managing cropland in McLean County are crusting, excess lime, excessive permeability, flooding, limited available water capacity, ponding, poor tilth, restricted permeability, a root- restrictive layer, water erosion, and wetness. Table 6 lists the limitations and hazards affecting cropland on the soils in the county that are in capability classes of 1 through 4. Crusting occurs when the average content of organic matter in the surface layer is 2.5 percent or less and the content of clay is more than 20 percent and less than or equal to 35 percent. Crusting occurs when flowing water or raindrops break down soil structural units, moving clay downward and leaving a concentration of sand and silt particles on the soil surface. Crusts can reduce the rate of water infiltration, increase the runoff rate, inhibit seedling emergence and growth, and reduce oxygen diffusion to seedlings. Generally, the structure of the surface layer is weak, and a crust forms on the surface during periods of heavy rainfall. Camden, Fincastle, Miami, and Strawn are examples of soils that are subject to crusting because they have a surface layer with a low content of organic matter. Measures that control surface crusting and improve tilth are those that protect the surface from the impact of raindrops and flowing water. Incorporating green manure crops, manure, or crop residue into the soil and applying a system of conservation tillage improve tilth. Excess lime is a limitation where the calcium carbonate equivalent is 15 percent or more within 16 inches of the surface. The high content of carbonates affects the availability of many plant nutrients and influences the effectiveness of herbicides. Excess lime is a management concern in areas of Harpster soils. This limitation can be overcome by incorporating green manure crops, manure, or crop residue into the soil; applying a system of conservation tillage; and using conservation cropping systems. Frequent applications of a small amount of fertilizer are needed to correct nutrient imbalances. Crops may respond well to additions of phosphate fertilizer. Applications of McLean County, Illinois 147 Figure 9.—An area of Sawmill and Lawson soils where a permanent cover of grasses, forbs, shrubs, or trees reduces the hazard of bank erosion along the rain-swollen Mackinaw River. herbicide should be adjusted as the level of alkalinity increases. Excessive permeability is a limitation where the lower limit of the permeability rate is 6.0 inches or more per hour within the top 60 inches of the soil and the slope is 25 percent or less. Excessive permeability can occur in soils that have high amounts of sand or gravel or that have many large-diameter pores. The capacity of the soils to retain moisture for plant use is limited. Deep leaching of nutrients and pesticides can increase the risk of ground-water pollution. Fox, Lorenzo, and Warsaw are examples of soils that may exhibit excessive permeability. Irrigation can supply the moisture needed for crops. Frequent applications of a small amount of fertilizer are needed. One application of a large amount can result in excessive loss of plant nutrients through leaching. Flooding is a hazard where the soil is commonly, occasionally, frequently, or very frequently flooded. Flooding occurs in unprotected areas along the major rivers and their tributaries. Dikes or diversions reduce the extent of the crop damage caused by floodwater. Flooding is a hazard on approximately 35,600 acres in McLean County. Most of the affected soils are occasionally flooded by stream overflow. In these areas flooding is expected infrequently under normal weather conditions, or about 5 to 50 times in 100 years. Damage to crops, particularly winter small grain crops, occurs in some years. Aetna, Huntsville, Lawson, Radford, Ross, and Sawmill are examples of soils that are subject to occasional flooding for brief periods. Some areas of the poorly drained Sawmill soils are frequently flooded for brief periods. Dikes, levees, and floodwater diversions can protect the adjacent soils and help to prevent crop damage. Surface drainage ditches can help to remove floodwater where suitable outlets are available. Management of drainage in conformance with regulations influencing wetlands may require special permits and extra planning. The flood-prone soils are better suited to crop varieties that require a relatively short growing season than to other varieties. Planting crops that are adapted to a shorter growing season 148 Soil Survey of Figure 10.—A 10-inch main tile outlet into a surface drainage ditch in an area of Drummer and El Paso silty clay loams, 0 to 2 percent slopes. and wetter conditions reduces the risk of crop damage caused by floodwater. Controlling runoff from the higher areas within the watershed reduces the frequency and severity of flooding. Changing land use from cropland to pasture or forestland minimizes economic damage. Limited available water capacity is a limitation where the slope is 25 percent or less and the amount of plant-available water to a depth of 60 inches or to a limiting layer above 60 inches is less than 6 inches. Available water capacity is the volume of water that is be available to plants when the soil is at field capacity. It is important in developing water budgets, predicting droughtiness, designing irrigation systems, protecting water resources, and predicting yields. Fox, Lorenzo, and Warsaw are examples of soils with limited available water capacity. Increasing the content of organic matter in the surface soil, selecting plant species that are tolerant of drought, applying a system of conservation tillage, using conservation cropping systems, and incorporating green manure crops, manure, or crop residue into the soil can help overcome this limitation. Ponding is a limitation in areas where the seasonal high water table is above the surface. It occurs for very brief, brief, long, or very long periods. The standing water is removed only by deep percolation or evaporation. Ponding decreases aeration and increases nutrient losses. Ashkum, Drummer, Peotone, and Sawmill soils are subject to ponding. Land grading helps to control ponding. Surface ditches and surface inlet tile also can help to remove the excess water if suitable outlets are available. Management of drainage in conformance with wetland regulations may require special permits and extra planning. Poor tilth is a limitation where the content of clay in the surface layer is 27 percent to less than 35 percent and the content of organic matter is less than 4 percent or where the content of clay is 35 percent or more. Poor tilth can occur in areas where the surface soil has been thinned by erosion. In these areas part of the subsoil is incorporated into the plow layer. The incorporation of subsoil material into the plow layer decreases the amount of organic matter and increases the content of clay in the surface soil. During periods of heavy rainfall, a crust commonly forms on the surface. Poor tilth also occurs in poorly drained soils with a high content of clay, regardless of the content of organic matter, and in soils that have been excessively tilled. Soils with poor tilth generally have a surface layer that is sticky when wet and hard and cloddy when dry. They can be tilled only within a narrow range of moisture content. As a result of the cloddiness, seedbed preparation is difficult. Poor tilth and surface crusting inhibit seedling germination and emergence, increase the runoff rate and the hazard of erosion, and reduce the rate of water infiltration. Sloping fields commonly have clayey spots where the subsoil is exposed. Preparing a good seedbed and tilling are difficult in these spots because the original friable surface layer has been lost through erosion. Soils that have good tilth are granular and porous and have a high content of organic matter in the surface layer. Plano, Osco, and Clare are examples of soils that are characterized by good tilth. Soils that have poor tilth generally have more clay, a lower content of organic matter, and weaker soil structure in the surface layer. Ashkum and Peotone soils have a surface layer of silty clay loam with more than 35 percent clay. If these soils are plowed when too wet, they become cloddy. Measures that minimize surface crusting and improve tilth are those that protect the surface from the impact of raindrops and flowing water. Incorporating green manure crops, manure, or crop residue into the soil, regularly adding other organic McLean County, Illinois 149 material, minimizing tillage, using a system of conservation tillage in which the field is tilled at nearly optimal soil moisture conditions improve tilth. Surface cloddiness can be controlled by avoiding tillage when the soil is too wet or by no-till farming. Restricted permeability is a limitation where the soil has a very slowly permeable or slowly permeable layer within 40 inches of the surface. The permeability rate is less than 0.2 inch per hour. Permeability is the quality that enables water or air to move through the soil. It affects irrigation and drainage systems, conservation management structures, and plantings. Soils that have slowly permeable or very slowly permeable layers, such as Varna, Elliott, and Swygert soils, have a higher potential for surface runoff and drain more slowly than more permeable soils. Soils with slow or very slow permeability require tile spacing of 50 to 70 feet and may require surface ditches for adequate subsurface drainage. A root-restrictive layer is a limitation where dense material, a natric horizon, bedrock, or a fragipan is within 40 inches of the surface. A root-restrictive layer can increase the susceptibility of the soil to erosion and limit the effectiveness of drainage systems. Root- restrictive layers affect plant growth by limiting the amount of plant nutrients and available water. Dana, Miami, Swygert, and Varna are examples of soils that have dense material within 40 inches of the surface. A combination of conservation measures, including special tillage practices, incorporation of organic matter into the soil, and suitable crop selection, can help to overcome this limitation. Water erosion is a hazard where the Kw factor multiplied by the slope is more than 0.8 and the slope is 3 percent or more. Erosion can occur when the surface soil is not protected against the impact of raindrops. Erosion reduces soil aggregate stability and thus reduces the rate of water infiltration and increases the rate of surface runoff (Brady, 1984). Soils on long or steep slopes are more susceptible to water erosion than soils on short or gentle slopes. Sheet or rill erosion is a hazard in areas where slopes are more than 2 percent or in areas where slopes are longer or are subject to concentrated flow. Excessive runoff decreases the quality of surface water through sedimentation and contamination by agricultural chemicals attached to soil particles in the sediment. The sediment enters streams, rivers, water impoundments, and road ditches. Water erosion is a hazard on about 37 percent of the total land area in the county. Camden, Catlin, Dana, Miami, and Wyanet are examples of soils that are subject to water erosion. Erosion can be controlled by a conservation tillage system that leaves crop residue on the surface after planting or by a cropping sequence that includes grasses and legumes. On soils with long, uniform slopes, contour farming and/or terraces in combination with a conservation tillage system can help to control erosion. Control of sedimentation is needed in order to maintain proper drainage. Removal of the sediments is expensive. Management measures that control water erosion help to reduce the extent of sedimentation and improve the quality of water available for rural, municipal, and recreational uses and for fish and wildlife. Wetness is a limitation where the seasonal high water table is at a depth of 1.5 feet or less. It is a management concern on much of the acreage used for crops in McLean County. Some soils are naturally so wet that the production of crops generally is not possible unless a drainage system is installed. The poorly drained Ashkum, Drummer, Edgington, Elpaso, Harpster, Hartsburg, Peotone, Sable, and Sawmill soils are examples of soils that are limited by wetness. Seasonal wetness in areas of somewhat poorly drained soils, such as Ipava, Flanagan, Lawson, Aetna, and Radford soils, can delay planting in wet years. Most of the soils in the county that require drainage are already drained by tile, but many drainage systems are old and should be replaced if maximum efficiency is to be achieved. Subsurface drains can help to lower the seasonal high water table if suitable outlets are available. In soils with a high content of clay and restricted permeability, subsurface drainage may not be practical. In these soils surface ditches may help to reduce the wetness. Management of drainage in conformance with regulations influencing wetlands may require special permits and extra planning. Limitations and Hazards Affecting Pasture Growing legumes, cool-season grasses, and warm- season grasses that are suited to the soils and climate of the county helps to maintain productive pastures. Suitable pasture and hay plants include several legumes, cool-season grasses, and native warm- season grasses. The legumes commonly grown in the county are alfalfa, red clover, alsike clover, and ladino clover. Alfalfa grows best on well drained soils, such as Proctor and Plano soils, and on moderately well drained soils, such as Catlin and Clare soils. It also is suitable on some of the somewhat poorly drained soils, such as Atterberry, Flanagan, and Raub soils, but wetness can be a limitation. Other legumes, such as alsike clover, red clover, and ladino clover, are more tolerant of the wetter conditions. 150 Soil Survey of The cool-season grasses commonly grown in the county include smooth bromegrass, orchardgrass, and tall fescue. These grasses can be grown alone or in mixtures with legumes. Native warm-season grasses, such as indiangrass, big bluestem, and switchgrass, grow very well in the summer. The management required for warm-season grasses differs from the management required for cool-season grasses. Proper grazing management is essential for the production of high-quality forage, stand survival, and erosion control. This management helps the plants to maintain sufficient and generally vigorous top growth during the growing season (fig. 11). Brush control is essential in many areas, and weed control is generally needed. Rotational grazing, deferred grazing when the soil is wet, and applications of lime and fertilizer according to the results of soil tests also are important management practices. The main concerns in managing pasture in McLean County are an equipment limitation, excess lime, flooding, frost heave, limited available water capacity, low pH, ponding, poor tilth, a root-restrictive layer, water erosion, and wetness. Table 6 lists the limitations and hazards affecting pastures on the soils in the county that are in capability classes 1 through 6. An equipment limitation occurs where the slope is more than 18 percent. This limitation can cause rapid wear of equipment. Also, it can hinder fertilization, harvest, pasture renovation, and seedbed preparation. The use of equipment is limited by the slope of the moderately steep and steep Miami, Hennepin, and Strawn soils. Excess lime is a limitation where the calcium carbonate equivalent is 15 percent or more within 16 inches of the surface. The high content of carbonates affects the availability of many plant nutrients and influences the effectiveness of herbicides. Excess lime is a management concern in areas of Harpster soils. Frequent applications of a small amount of fertilizer are needed to correct nutrient imbalances. Pasture plants may respond well to additions of phosphate fertilizer. Applications of herbicide should be adjusted as the level of alkalinity increases. Flooding is a hazard where the soil is occasionally or frequently flooded. Flooding occurs in unprotected areas along the major rivers and their tributaries. Surface drainage ditches can help to remove floodwater where suitable outlets are available. Flooding may damage pasture plants in some years. Aetna, Huntsville, Lawson, Radford, Ross, and Sawmill soils are subject to flooding. Figure 11.—Pasture in an area of sloping Strawn and La Rose soils. Proper grazing management improves the vigor and reproduction of desirable plants. McLean County, Illinois 151 Dikes and diversions minimize the extent of the damage caused by floodwater. Selecting forage and hay varieties adapted to shorter growing seasons and wetter conditions reduces the extent of flood damage. Restricted use during wet periods helps to keep the pasture in good condition. Management of drainage in conformance with regulations may require special permits and extra planning. Frost heave is a limitation where the potential for frost action is moderate or high and the soil is poorly drained or very poorly drained. Frost heave occurs in soils when ice lenses or bands develop into or push an ice wedge between two layers of soil near the surface layer. The ice wedges heave the overlying soil layer upward, snapping the roots. Soils with a low content of sand have small pores that hold water and enable ice lenses to form. Ashkum, Drummer, and Selma are among the soils that are susceptible to frost heave. Selecting adapted forage and hay varieties reduces the effects of frost heave. Timely rotation of grazing maintains a surface cover that insulates the soil and thus minimizes frost heave. Leaving stubble, 4 to 6 inches high, on a pasture in winter and planting grass- legume mixtures also minimize frost heave. Limited available water capacity is a limitation where the slope is 25 percent or less and the amount of plant-available water to a depth of 60 inches or to a limiting layer above 60 inches is less than 6 inches. Available water capacity is the volume of water that is be available to plants when the soil is at field capacity. Fox, Lorenzo, and Warsaw are examples of soils with a limited available water capacity. Increasing the content of organic matter in the surface layer and selecting plant species that are tolerant of drought can improve the pasture in areas of soils with a limited available water capacity. Low pH is a limitation where the pH is 5.5 or less within a depth of 40 inches. This limitation can cause toxicity or decrease the availability of plant nutrients, either of which affects the health and vigor of the plants. Many soils in McLean County have low pH. Camden, Keomah, and Osco soils are examples. Selecting adapted forage and hay varieties and applying lime according to the results of soil tests help to overcome this limitation. Planting species that are more tolerant of acidic conditions, such as red clover and alsike clover, can increase the quantity and improve the quality of livestock forage. Ponding is a limitation in areas where the seasonal high water table is above the surface. Ponding decreases aeration and increases nutrient losses. Ashkum, Drummer, Peotone, and Sawmill soils are subject to ponding. Land grading helps to control ponding. Surface ditches and surface inlet tile also can help to remove the excess water if suitable outlets are available. Management of drainage in conformance with wetland regulations may require special permits and extra planning. Selecting forage and hay varieties adapted to wet conditions improves forage production. Restricted use during wet periods helps to keep the pasture in good condition. Poor tilth is a limitation in areas where the surface layer has 27 to 35 percent clay and less than 4 percent organic matter or where it has a clay content of 35 percent or more. Poor tilth can occur in soils when part of the subsoil is incorporated into the plow layer because of erosion. Incorporation of subsoil material decreases the amount of organic matter and increases the content of clay in the surface soil. Heavy rainfall often causes surface crusting. Poor tilth also occurs in poorly drained soils with a high content of clay, regardless of the content of organic matter, and in soils that have been excessively tilled. Poor tilth decreases the rate of water infiltration and increases the runoff rate and the susceptibility to erosion on the more sloping soils. Soils with poor tilth generally have a surface layer that is sticky when wet and hard and cloddy when dry. They can be tilled only within a narrow range of moisture content. As a result, seedbed preparation is difficult. When pastures are established or renovated, minimizing tillage and applying conservation tillage operations during periods when soil moisture conditions are optimal or nearly optimal can improve tilth. A root-restrictive layer is a limitation where dense material, a natric horizon, bedrock, or a fragipan is within 40 inches of the surface. A root-restrictive layer can increase the susceptibility of the soil to erosion and limit the effectiveness of drainage systems. Root- restrictive layers affect plant growth by limiting the amount of plant nutrients and available water. Dana, Miami, Swygert, and Varna are examples of soils that have dense material within 40 inches of the surface. A combination of conservation measures, including special tillage practices, incorporation of organic matter into the soil, and selection of adapted forage and hay varieties, can help to overcome this limitation. Water erosion is a hazard where the Kw factor multiplied by the slope is more than 1.0 and the slope is 3 percent or more. Erosion can occur in overgrazed areas or during pasture establishment and renovation when the surface soil is not protected against the impact of raindrops. The impact of raindrops causes 152 Soil Survey of poor tilth, which reduces the rate of water infiltration and increases the runoff rate. Water erosion reduces the productivity of the soil. Also, the eroding sediments, livestock manure, and added nutrients enter streams, rivers, water impoundments, and road ditches. Camden, Catlin, Dana, Miami, and Wyanet are examples of soils that are subject to water erosion. Soils on long or steep slopes are also more susceptible to water erosion than soils on short or gentle slopes. Rotation grazing, which prevents overgrazing and thus prevents surface compaction and excessive runoff, helps to control erosion. Tilling on the contour, using a no-till system of seeding when a seedbed is prepared or the pasture is renovated, and selecting adapted forage and hay varieties also help to control erosion. Wetness is a limitation where the seasonal high water table is at a depth of 1.5 feet or less. It is a management concern on much of the acreage used for pasture in McLean County. The poorly drained Ashkum, Drummer, Edgington, El Paso, Harpster, Hartsburg, Peotone, Sable, and Sawmill soils are examples of soils that are limited by wetness. Most of the soils needing drainage are already drained by tile, but many drainage systems are old and should be replaced for maximum efficiency. Subsurface drains can help to lower the seasonal high water table if suitable outlets are available. In soils with a high content of clay and restricted permeability, subsurface drainage may not be practical. In these soils surface ditches may help to reduce the wetness. Management of drainage in conformance with regulations influencing wetlands may require special permits and extra planning Yields per Acre The average yields per acre that can be expected of the principal crops under a high level of management are shown in table 7. In any given year, yields may be higher or lower than those indicated in the table because of variations in rainfall and other climatic factors. The land capability classification of map units in the survey area also is shown in the table. The yields are based mainly on the experience and records of farmers, conservationists, and extension agents (Fehrenbacher et al., 1978). Available yield data from nearby counties and results of field trials and demonstrations also are considered. The management needed to obtain the indicated yields of the various crops depends on the kind of soil and the crop. Management can include drainage, erosion control, and protection from flooding; the proper planting and seeding rates; suitable high- yielding crop varieties; appropriate and timely tillage; control of weeds, plant diseases, and harmful insects; favorable soil reaction and optimum levels of nitrogen, phosphorus, potassium, and trace elements for each crop; effective use of crop residue, barnyard manure, and green manure crops; and harvesting that ensures the smallest possible loss. The estimated yields reflect the productive capacity of each soil for each of the principal crops. Yields are likely to increase as new production technology is developed. The productivity of a given soil compared with that of other soils, however, is not likely to change. Crops other than those shown in table 7 are grown in the survey area, but estimated yields are not listed because the acreage of such crops is small. The local office of the Natural Resources Conservation Service or of the Cooperative Extension Service can provide information about the management and productivity of the soils for those crops. Land Capability Classification Land capability classification shows, in a general way, the suitability of soils for most kinds of field crops. Crops that require special management are excluded. The soils are grouped according to their limitations for field crops, the risk of damage if they are used for crops, and the way they respond to management. The criteria used in grouping the soils do not include major and generally expensive landforming that would change slope, depth, or other characteristics of the soils, nor do they include possible but unlikely major reclamation projects. Capability classification is not a substitute for interpretations designed to show suitability and limitations of groups of soils for rangeland, for forestland, or for engineering purposes. In the capability system, soils are generally grouped at three levels—capability class, subclass, and unit (USDA, 1961). Only capability class and subclass are used in this survey. Capability classes, the broadest groups, are designated by the numbers 1 through 8. The numbers indicate progressively greater limitations and narrower choices for practical use. The classes are defined as follows: Class 1 soils have slight limitations that restrict their use. Class 2 soils have moderate limitations that restrict the choice of plants or that require moderate conservation practices. McLean County, Illinois 153 Class 3 soils have severe limitations that restrict the choice of plants or that require special conservation practices, or both. Class 4 soils have very severe limitations that restrict the choice of plants or that require very careful management, or both. Class 5 soils are subject to little or no erosion but have other limitations, impractical to remove, that restrict their use mainly to pasture, rangeland, forestland, or wildlife habitat. Class 6 soils have severe limitations that make them generally unsuitable for cultivation and that restrict their use mainly to pasture, rangeland, forestland, or wildlife habitat. Class 7 soils have very severe limitations that make them unsuitable for cultivation and that restrict their use mainly to grazing, forestland, or wildlife habitat. Class 8 soils and miscellaneous areas have limitations that preclude commercial plant production and that restrict their use to recreational purposes, wildlife habitat, watershed, or esthetic purposes. Capability subclasses are soil groups within one class. They are designated by adding a small letter, e, w, s, or c, to the class numeral, for example, 2e. The letter e shows that the main hazard is the risk of erosion unless close-growing plant cover is maintained; w shows that water in or on the soil interferes with plant growth or cultivation (in some soils the wetness can be partly corrected by artificial drainage); s shows that the soil is limited mainly because it is shallow, droughty, or stony; and c, used in only some parts of the United States, shows that the chief limitation is climate that is very cold or very dry. In class 1 there are no subclasses because the soils of this class have few limitations. Class 5 contains only the subclasses indicated by w, s, or c because the soils in class 5 are subject to little or no erosion. They have other limitations that restrict their use to pasture, rangeland, forestland, wildlife habitat, or recreation. The capability classification of the soils in this survey area is given in the section “Soil Series and Detailed Soil Map Units” and in the yields table. Prime Farmland Prime farmland is one of several kinds of important farmland defined by the U.S. Department of Agriculture. It is of major importance in meeting the Nation’s short- and long-range needs for food and fiber. Because the supply of high-quality farmland is limited, the U.S. Department of Agriculture recognizes that responsible levels of government, as well as individuals, should encourage and facilitate the wise use of our Nation’s prime farmland. Prime farmland, as defined by the U.S. Department of Agriculture, is land that has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops and is available for these uses. It could be cultivated land, pastureland, forestland, or other land, but it is not urban or built-up land or water areas. The soil qualities, growing season, and moisture supply are those needed for the soil to economically produce sustained high yields of crops when proper management, including water management, and acceptable farming methods are applied. In general, prime farmland has an adequate and dependable supply of moisture from precipitation or irrigation, a favorable temperature and growing season, acceptable acidity or alkalinity, an acceptable salt and sodium content, and few or no rocks. It is permeable to water and air. It is not excessively erodible or saturated with water for long periods, and it either is not frequently flooded during the growing season or is protected from flooding. Slope ranges mainly from 0 to 6 percent. More detailed information about the criteria for prime farmland is available at the local office of the Natural Resources Conservation Service. Potentially, 704,736 acres in the survey area, or approximately 93 percent of the total acreage, meets the soil requirements for prime farmland. Some of this acreage is prime farmland only where certain conditions are met. Areas of this land are throughout the county. A recent trend in land use in some parts of the survey area has been the loss of some prime farmland to industrial and urban uses. The loss of prime farmland to other uses puts pressure on marginal lands, which generally are more erodible, droughty, and less productive and cannot be easily cultivated. The map units in the survey area that are considered prime farmland are listed in table 8. This list does not constitute a recommendation for a particular land use. On some soils included in the list, measures that overcome a hazard or limitation, such as flooding or wetness, are needed. Onsite evaluation is needed to determine whether or not the hazard or limitation has been overcome by corrective measures. The extent of each listed map unit is shown in table 5. The location is shown on the detailed soil maps. The soil qualities that affect use and management are described in the section “Soil Series and Detailed Soil Map Units.” 154 Soil Survey of Hydric Soils In this section, hydric soils are defined and described and the hydric soils in the survey area are listed. The three essential characteristics of wetlands are hydrophytic vegetation, hydric soils, and wetland hydrology (Cowardin et al., 1979; U.S. Army Corps of Engineers, 1987; National Research Council, 1995; Tiner, 1985). Criteria for each of the characteristics must be met for areas to be identified as wetlands. Undrained hydric soils that have natural vegetation should support a dominant population of ecological wetland plant species. Hydric soils that have been converted to other uses should be capable of being restored to wetlands. Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS) as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994). These soils are either saturated or inundated long enough during the growing season to support the growth and reproduction of hydrophytic vegetation. The NTCHS definition identifies general soil properties that are associated with wetness. In order to determine whether a specific soil is a hydric soil or nonhydric soil, however, more specific information, such as information about the depth and duration of the water table, is needed. Thus, criteria that identify those estimated soil properties unique to hydric soils have been established (Federal Register, 1995). These criteria are used to identify a phase of a soil series that normally is associated with wetlands. The criteria used are selected estimated soil properties that are described in “Soil Taxonomy” (Soil Survey Staff, 1999) and “Keys to Soil Taxonomy” (Soil Survey Staff, 1998) and in the “Soil Survey Manual” (Soil Survey Division Staff, 1993). If soils are wet enough for a long enough period to be considered hydric, they should exhibit certain properties that can be easily observed in the field. These visible properties are indicators of hydric soils. The indicators used to make onsite determinations of hydric soils in this survey area are specified in “Field Indicators of Hydric Soils in the United States” (Hurt et al., 1998). Hydric soils are identified by examining and describing the soil to a depth of about 20 inches. This depth may be greater if determination of an appropriate indicator so requires. It is always recommended that soils be excavated and described to the depth necessary for an understanding of the redoximorphic processes. Then, using the completed soil descriptions, soil scientists can compare the soil features required by each indicator and specify which indicators have been matched with the conditions observed in the soil. The soil can be identified as a hydric soil if at least one of the approved indicators is present (National Research Council, 1995; Hurt et al., 1998). Map units that are made up of hydric soils may have small areas, or inclusions, of nonhydric soils in the higher positions on the landform, and map units made up of nonhydric soils may have inclusions of hydric soils in the lower positions on the landform. Table 9 indicates the hydric and nonhydric soils identified in the names of the detailed map units in the county. The table also identifies the included soils that are considered hydric. Onsite investigation is recommended to determine whether hydric soils occur and the location of the included hydric soils. Windbreaks and Environmental Plantings Windbreaks are needed in some areas in McLean County where the soils are subject to wind erosion. Wind erosion is a moderate hazard on some soils in the county where the surface is not protected. These soils have a surface layer of very fine sandy loam or sandy loam or have a high content of finely divided calcium carbonate or a high content of clay in the surface layer. Harpster soils have a high content of calcium carbonate in the surface layer. Ashkum and Peotone soils have a high content of clay in the surface layer. Windbreaks protect livestock, buildings, yards, fruit trees, gardens, and cropland from wind and snow; help to keep snow on fields; and provide food and cover for wildlife. Field windbreaks are narrow plantings made at right angles to the prevailing wind and at specific intervals across the field. The interval depends on the erodibility of the soil. Environmental plantings help to beautify and screen houses and other buildings and to abate noise. The plants, mostly evergreen shrubs and trees, are closely spaced. To ensure plant survival, a healthy planting stock of suitable species should be planted properly on a well prepared site and maintained in good condition. Table 10 shows the height that locally grown trees and shrubs are expected to reach in 20 years on various soils. The estimates in table 10 are based on measurements and observation of established plantings that have been given adequate care. They can be used as a guide in planning windbreaks and McLean County, Illinois 155 screens. Additional information on planning windbreaks and screens and planting and caring for trees and shrubs can be obtained from the local office of the Natural Resources Conservation Service or of the Cooperative Extension Service or from a commercial nursery. Woodland In the early 1800s, forests covered about 10.9 percent of the land in McLean County (Iverson et al., 1989). Since then, most of the trees have been cleared from the areas best suited to cultivation. By 1997, only 7,803 acres, or about 1 percent of the total acreage of the county, remained as woodland (fig. 12; USDA, 1997). Most of the woodland is privately owned. The most common trees in the uplands are white oak, black oak, northern red oak, shagbark hickory, white ash, green ash, sugar maple, silver maple, boxelder, black walnut, black cherry, and American elm. The most common trees on flood plains are cottonwood, sycamore, willow, bur oak, pin oak, swamp white oak, hackberry, and silver maple. The remaining woodland is dominantly in areas that are too steep, too wet, or too isolated for cultivation. Most of these areas are along the drainageways of the Mackinaw and Sangamon Rivers and Kickapoo and Sugar Creeks. If properly managed, the soils in these forested areas are generally well suited to high-quality trees (fig. 13). The productivity of many of the remaining forest stands could be improved by proper management. Exclusion of livestock, protection from fire, insects, and diseases, proper logging methods, and proven silvicultural methods that enhance growth and regeneration are needed in these areas. Forest Productivity Table 11 can help woodland owners or managers plan the use of soils for wood crops. In this table, the potential productivity of merchantable or common trees on a soil is expressed as a site index and as a [Tp Bjfo mi pi It y P&jl 4 j VM rjt: 35 1 1 American Blackhaw, cockspur Austrian pine. 1 1 1 Norway spruce. 1 I 1 Carolina poplar. 1 cranberrybush, hawthorn, common Douglas fir. 1 blackgum, common 1 eastern cottonwood. 1 Canada yew, black pawpaw, common arborvitae, blue 1 hackberry, green 1 pin oak I chokeberry, common serviceberry. spruce, common 1 ash, red maple. 1 1 elderberry, common prairie crabapple. persimmon, eastern 1 swamp white oak. 1 1 juniper, common roughleaf dogwood. redcedar, green 1 sweetgum 1 1 ninebark, common rusty blackhaw. hawthorn. 1 1 1 winterberry. southern arrowwood. nannyberry, pecan. 1 1 1 northern spicebush, 1 redosier dogwood, 1 silky dogwood witchhazel shingle oak 1 1 1 1 1 1 1 1 1 I 1 American hazelnut.
