2 CONNECnCUT AGRICULTURAL STATION, BULL. 120. 
 
 Notice as to Bulletins. 
 
 The Bulletins of this Station are mailed free to citizens of 
 Connecticut who apply for them, and to others, as far as the 
 limited editions permit. 
 
 Applications should be renewed annually before January 1st. 
 
 The matter of all the Bulletins of this Station, in so far as it 
 is new and of permanent value, will be made j^art of the Annual 
 Report. 
 
 B^^AU Bulletins earlier than No. 71 and alsoNos. 83, 93, 100, 
 101, 102, 106, 111 and 118, are exhausted and cannot be supplied. 
 
 Notice as to Supplt of Station Reports. 
 
 The Annual Report of this Station, printed at State expense, is 
 by law limited to an edition of 12,000 copies, of which 5,000 
 copies are bound with the Annual Report of the Connecticut 
 State Board of Agriculture, and distributed by the Secretary of 
 the Board, T. S. Gold, West Cornwall, Conn. 
 
 After exchanging with other Experiment Stations and Agricul- 
 tural Journals, the RejDorts remaining at the disposal of the Sta- 
 tion will be sent to citizens of Connecticut who shall seasonably 
 apply for them, and to others as long as the supply lasts. 
 
 I^^The Station has no supply of its Annual Rejaorts for the years 
 1877, 1878, 1879, 1880, 1881, 1883, 1887, 1891, and 1893, but 
 some of them may be obtained from Secretary T. S. Gold. 
 
 Notice Regarding the Fertilizer Law. 
 
 Persons who mix fertilizers, whether on a farm or in a factory, 
 and sell these mixtures within the State of Connecticut, must, 
 under the terms of the Fertilizer Law, pay analysis fees on such 
 mixtures and meet the other legal requirements. 
 
 Purchasers may club together to buy fertilizers, making one per- 
 son their agent for the purpose, or may pay one person for mixing 
 and bagging goods which they severally own, without limitation 
 by the law, but the sale of either fertilizer-chemicals, factory- 
 mixed or home-mixed fertilizers within this State, subjects the sel- 
 ler to the requirements and penalties of the law. 
 
FERTILIZEES. 
 
 TRADE-VALUES OF FERTILIZER INGREDIENTS IN 
 RAW MATERIALS AND CHEMICALS, FOR 1895. 
 
 The following schedule for the valuation of fertilizers in 1895 
 has been adopted by the Massachusetts, Rhode Island, New Jer- 
 sey and Connecticut Stations.

 In Mixed Fertilizers, organic nitrogen is reckoned at 16^ cents 
 per pound, the price of nitrogen in raw materials of the best 
 quality; insoluble phosphoric aeidis reckoned at 2 cents: 2^otash is, 
 rated at 4^ cents, if sufficient chlorine be present in the fertilizer 
 to combine with it to make muriate; if there is more potash 
 present than will combine with the chlorine, then this excess of 
 potash is reckoned at 5^ cents per pound, 
 
 * Dissolved from 2 grams of the unground phosphate previously extracted with 
 pure water, by 100 c. c. neutral solution of ammonium citrate, sp. gr. 1.09, in 30 
 minutes, at 65° C, with agitation once in five minutes. Commonly called " re- 
 verted" or "backgone" Phosphoric Acid.

 ANALYSES OF FERTILIZERS. 
 Reported by E, H. Jenkins. 
 
 On the following pages will be found analyses of most of the 
 fertilizers which have been examined at this station since making 
 up the Annual Report for 1894. 
 
 These fertilizers are raw materials, such as are used by manu- 
 facturers or for home-mixing, or are applied to land unmixed. 
 All the analyses here given were made by Messrs. Winton and 
 Ogden, chemists of the Station. 
 
 Nitrate of Soda. 
 
 4:489. Sold by National Fertilizer Co. Bridgeport. Sent by 
 T, J. Stroud, Shaker Station. 
 
 4:511. Sold by National Fertilizer Co. Bridgeport. Sent by 
 S. E. Curtiss, Stratford. 
 
 These samples contain 16.24 and 10.37 per cent, of nitrogen 
 respectively. The regular retail price was $50.00 per ton. At 
 this price the nitrogen cost 15.4 and 15.2 cents per pound 
 respectively, which is a little less than the average cost in this 
 State, because the two samples contained more nitrogen than is 
 usually found in this article. 
 
 Dry Fish. 
 
 4548. Sold by L. Sanderson, New Haven. From a lot bought 
 by the Station for experiment. 
 
 4514. Sold by G. W. Miles, Milford. Sent by W. L. and 
 S. T. Merwin, Milford.

FERTILIZERS. 5 
 
 The per cent, of nitrogen in the sample of fish from L, Sander- 
 son, 4548^ is exceptionally high. Eight per cent, is the average 
 amount. With 8 per cent, of nitrogen the cost per pound of 
 nitrogen would have been about 16 cents. 
 
 Dried Blood. 
 
 454-4. Sold by L. Sanderson. Sample from lot sold to this 
 Station for experiment. 
 
 It contained 13.40 per cent, of nitrogen and 1.54 of phosphoric 
 acid. Allowing 5 cents per pound for phosphoric acid the nitro- 
 gen costs 14.4 cents per pound. 
 
 CoTTOK Seed Meal. 
 
 On the next page are given the analyses of Cotton Seed Meal 
 recently made at this Station. 
 
 For "valuation" of cotton seed meal the pound of nitrogen is 
 reckoned at 12 cents, of phosphoric acid at 5 cents and of potash 
 at 5^ cents. Since phosphoric acid and potash are present in 
 small proportion it is not needful to determine their exact amount 
 in every sample, but the valuation is made sufficiently exact by 
 using the average quantities in which they occur. 
 
 The retail cost of organic nitrogen in 12 lots of meal has ranged 
 from 9.9 cents to 13.4 cents per pound or on the average 11.9 
 cents. 
 
 The price of cotton seed meal is this year lower than ever, and 
 there is nothing which supplies available organic nitrogen for fer- 
 tilizers so cheaply. This material has long been used on tobacco 
 with success and is now employed extensively as a fertilizer for 
 other crops. 
 
 There is in some quarters a belief that the nitrogen of cotton 
 seed meal is not as readily available as that from animal matter, 
 fish, tankage, bone, etc. 
 
 Our knowledge regarding the relative availability of the various 
 forms of organic nitrogen is scanty, but there are facts which 
 indicate that cotton seed meal, castor pomace, linseed meal and 
 the like, are equal if not superior to many forms of animal matter 
 as sources of nitrogen for crops. 
 
 Thus cotton seed meal or castor pomace is used exclusively by 
 many of the most successful tobacco growers as a nitrogen supply 
 for tobacco, a crop which makes large demands on the soil-nitro- 
 gen and, occupying the land less than three months, requires plant

FERTILIZEES. 7 
 
 food ill quickly available forms. Were the nitrogen of cotton 
 seed meal not quickly available it could hardly meet the needs of 
 this crop. The fact, however, that tobacco growers use quanti- 
 ties of meal presumably much in excess of the crop requirements, 
 somewhat weakens the argument. 
 
 In the Eighteenth Report of this Station, pp. 99, 100, are given 
 the results of three years' exact experiments made by Wagner 
 on small plots of soil, in which he tested the relative value of 
 various forms of organic nitrogen on a rotation consisting of sum- 
 mer rye, flax, summer Avheat and carrots. Castor pomace was 
 thus compared with nitrate of soda, dried blood, fish, steamed 
 bone and other materials. 
 
 If the availability of the nitrogen of nitrate of soda is called 
 100 then in the first year the relative availability of the nitrogen 
 of blood was 67, of castor pomace 62, while that of fish and ' 
 bone meal was 51 and 42 respectively. 
 
 The average of two years tests on the same soil was 67 and 65 
 for blood and castor pomace, 59 and 53 for fish and bone meal. 
 
 The average of three years tests on the same soil was 69 and 
 67 for blood aud castor pomace, 64 and 61 for fish and bone. 
 Experiments in pots gave results not essentially difl^erent from 
 these. 
 
 Experiments of the same kind made at this Station in 1894, 
 18th Report, p. 96, in which corn was grown in pots with the dif- 
 ferent fertilizers showed " that under the conditions of this experi- 
 ment, of the organic forms of nitrogen, castor pomace B was the 
 most available, 85 per cent., wben nitrate of soda equals 100 per 
 cent. Somewhat less available was the nitrogen of linseed meal, 
 80, and of blood, 77 per cent. Next came cotton seed meal, 76, 
 castor pomace A, 74, and horn and hoof 72 per cent. Last came 
 dry fish, 70, and tankage 68 per cent." 
 
 These exact experiments indicate that the nitrogen of vegeta- 
 ble matters like those named, is as readily available to crops as 
 that of most forms of animal matter. Even if the vegetable nitro- 
 gen were somewhat inferior, the lower price might still make it 
 the more economical to use. 
 
 Farmers should specify in ordering, bright^ hulled or decorti- 
 cated meal, with not less than 6.6 per cent, of nitrogen. The low- 
 priced, dark, unhulled meal which contains between three and 
 four per cent, of nitrogen is uneconomical to use at current mar- 
 ket rates. The nitrogen of the hulls (cortex) is comparatively 
 worthless.

 Castor pomace should be mentioned among the sources of 
 organic nitrogen. No samples have yet been analyzed during the 
 present season. It is bought chiefly in the tobacco growing dis- 
 tricts and its use will probably not extend to other sections while 
 the prices of nitrogenous matters hold as they are now.

 The sales of 4493 and 4507 were in car lots for spot cash and 
 the price paid made the cost of available phosphoric acid less 
 than three cents per pound. 
 
 Available phosphoric acid can be bought in dissolved rock 
 phosphate very considerably cheaper than in dissolved bone black, 
 which has hitherto been almost the only source of soluble phos- 
 phoric acid for those who mix their own fertilizers. 
 
 Dissolved rock phosphate has been chiefly U'sed hitherto by 
 manufacturers of mixed fertilizers, and two objections have been 
 urged against its use for home-mixtures. 
 
 It has been claimed, in the first place, that the phosphoric acid 
 of dissolved rock is not as available to crops as that of the more 
 expensive dissolved bone black. This claim is absolutely without 
 foundation. G-round rock phosphate is usually extremely slow in 
 its action on crops. The same is true of waste bone black, as it 
 is of bone ash. But when phosphoric acid has been brought into 
 
 * Regular retail rate. 
 
FERTILIZEES. 9 
 
 solution in water, this soluble phosphoric acid is, in general, of 
 the same value whatever the source from which it came. 
 
 In the second place, dissolved rock phosphate is likely to cake 
 or set when stored for some time and hence to require screening 
 or milling before it can be used. If it is mixed with a large pro- 
 portion of muriate or sulphate of potash or nitrate of soda, it will 
 sometimes cake together even harder than when unmixed. 
 
 If, however, enough animal or vegetable matter is present no 
 such inconvenience need be feared. 
 
 To illustrate : Mr. J. N. Barnes, of Yalesville, made two mix- 
 tures in the spring of 1894. One contained 1200 pounds of tank- 
 age, 300 of dissolved rock phosphate, 350 of nitrate of soda, and 
 150 of muriate of potash. 
 
 The other consisted of 100 pounds of fine bone, 600 of nitrate 
 of soda, 325 of muriate of potash and 975 of dissolved rock 
 phosphate. A portion of each lay in bags in the barn till Octo- 
 ber. At that time the mixtures were in excellent condition. 
 There were no lumps which did not fall apart on emptying the 
 bags. 
 
 Odorless Mineral Guano. 
 
 This material, — wholly distinct from " Odorless Phosphate," 
 which is a basic slag pi-oduced in the manufacture of steel — is 
 ofiered by The Forest City Wood Ash Co., of Boston. It is the 
 soft phosphate of Florida and claimed to be the " best fertilizer 
 on the market." 
 
 A sample 4499 received from T. J. Stroud, of Shaker Station, 
 contained 20.52 per cent, of phosphoric acid, of which 1.'79 per 
 cent, was soluble in ammonium citrate and in that sense " avail- 
 able." 
 
 At reasonable prices this material may be profitably used on 
 soils which are known to be specially deficient in available phos- 
 phates and hence likely to be benefited by a heavy application 
 of some phosphate which will furnish phosphoric acid to the crop 
 year after year. 
 
 Muriate of Potash. 
 
 This is at present the cheapest source of available potash in our 
 market. It is quite constant in composition and is sold under 
 guarantee of 50 per cent, actual potash, though some lots contain 
 one per cent, less than this. 
 
10 CONNECTICUT AGRICULTURAL STATION, BULL. 120. 
 
 The retail price is at present from $42.50 to $45.00 per ton, 
 making the cost of actual potash from 4.2 to 4.45 cents per 
 pound. 
 
 4506. Was bought in N. Y. City by S. D. Woodrufi & Sons, 
 of Orange. 
 
 4512. Was bought by S. E. Curtiss, of Stratford. 
 
 The samples contained respectively 49.77 and 50.73 percent, of 
 potash. Both parties bought for cash^ for -141.60 and $41 per 
 ton, delivered in lots of several tons, but less than car lots, at 
 their freight station. 
 
 The cost of actual potash was therefore 4.2 cents and 4.0 cents 
 per pound respectively.

 The analyses show the usual variations. 4523 has about the 
 composition of domestic hard-wood ashes. 4485 and 4515 are 
 of very poor quality. 
 
 4515. Was bought on guarantee of five per cent, of potash 
 soluble in water, and the purchaser secured a rebate on the 
 amount paid for them. 
 
 The potash in these samples of wood ashes costs from 5.2 to 
 14.8 cents per pound, and on the average 9.8 cents, if we assume 
 that their value consists wholly in the potash and phosphoric

 acid which they contain, and reckon the latter at 5 cents per 
 pound. 
 
 The value of ashes, however, does not consist wholly in these 
 two ingredients. There are soils on \yhich the carbonate of lime 
 of which the ashes should contain sixty to seventy per cent., is 
 worth more than the potash itself. 
 
 Lime is not abundant in most of our Connecticut soils, and 
 the continued use of saline fertilizers, like potash salts, depletes 
 the soil supply of it. But a moderate quantity of carbonate of 
 lime in the soil is necessary in order to get the full effect of nitro- 
 genous fertilizers. 
 
 Instead of using "unleached" hard-wood ashes, which do not 
 contain more than St]- to 4 per cent, of soluble potash, it will pay 
 to use air-slacked lime with muriate of potash or cotton hull 
 ashes.

 In the table on page 12, the valuation is made by reckoning 
 potash, soluble, reverted and insoluble phosphoric acid at 5^, 
 6, 5|-, and 2 cents per pound respectively. The cost of water- 
 soluble potash is calculated by subtracting the valuation of the 
 phosphoric acid from the cost price and dividing the remainder 
 •by the number of pounds of potash contained in a ton. 
 
 All of the samples thus far examined this year, with one excep- 
 tion, have been of good quality. The cost per pound of potash 
 has ranged from 4.5 to 6.6 cents j)er pound, and has averaged 5.4 
 cents. There is no better form of potash known for the tobacco 
 crop. It is the general opinion of the best growers that the high 
 grade sulphate of potash is not well adapted for tobacco, the

FERTILIZERS. 13- 
 
 muriate as a rule cannot be used on smoking tobacco and 
 the choice therefore lies between the double sulphate of potash 
 and magnesia, and either wood ashes or cotton hull ashes. The 
 latter kind of ashes are much more economical when from 100 ta 
 150 or even 200 pounds of actual potash per acre are required 
 annually. 
 
 Cotton hull ashes, at present prices, are worth the attention of 
 fruit growers. One ton of cotton hull ashes will supply as much 
 potash as five tons of unleached wood ashes of average quality 
 and costs from $10 to $15 less. The quantity of lime however 
 would be very much less in the cotton hull ashes than in the 
 wood ashes. 
 
 High grade sulphate of potash, containing from 48 to 51 per 
 cent, of actual potash and the double sulphate of potash and mag- 
 nesia, often called " low-grade sulphate of potash," containing 
 from 25 to 27 per cent, of potash, are also in our market though 
 no samples have been analyzed during the present season. 
 
 The cost of potash per pound in these goods ranges from 5^ to 
 6 cents per pound, being usually a trifle higher in the double sul- 
 phate than in the high grade sulphate. 
 
 Summary. 
 
 1. Nitrogen is bought at the present time in Connecticut for 
 about the following prices at retail. 
 
 In nitrate of soda 15-i^ cents per pound. 
 
 Indried blood 14^ " " 
 
 In dried fish 13^-14^ " " 
 
 In cotton seed meal. 9.9-13| " " " 
 
 The nitrogen of cotton seed meal is as readily available as 
 that of most animal matter, fish, tankage, bone and the like. 
 
 2. So-called "available phosphoric acid" {i. e. soluble and 
 reverted taken together) costs at present, 2-|-3 cents less, per 
 pound, in " dissolved rock phosphate " than in " dissolved bone 
 black." 
 
 Soluble, (water-soluble) phosphoric acid is of equal value to 
 crops whether obtained from rock or bone. Reverted (citrate- 
 soluble) jDhosphoric acid probably works equally well, whatever 
 its source may be. When milled with nitrogenous animal or 
 vegetable matters in suitable quantity, dissolved rock phosphate 
 does not cake in the pile or in bags. 
 
14 CONNECTICUT AGETCULTURAL STATION, BULL. 120. 
 
 3. Muriate of potash is the cheapest source of potash which, in 
 this form, costs from 4|^ to 4^ cents per pound. 
 
 4. Canada ashes are so variable and commonly so poor in quality, 
 that they cannot serve economically as a source of potash. Their 
 fertilizing value however does not consist alone in the potash and 
 phosphoric acid they contain, but somewhat depends on the car- 
 bonate of lime which is their chief ingredient. 
 
 6, Cotton hull ashes, this spring, have been of good quality and 
 furnish potash for 5-| cents a poxmd on the average. They are 
 well worth the attention of orchardists as a substitute for Canada 
 ashes.

 found by the factor 6.25. 
 
 All the preparations appear to consist chiefly of meat and bone 
 having about the composition of " bone tankage " which is used

 They are quite alike in composition excepting that Breck's

 lime than either of the others and correspondingly more moisture 
 and mineral matters which consist in part of carbonate of lime.
