Prosperity Brand Ground Tankage Prosperity Brand Market Garden Prosperity Brand Potato and Vegetable Fertilizer INSPECTION OF 1924. During the year, Mr. Churchill, the sampling agent of the Station, has visited ninety-six towns and villages in the State and has taken 592 official samples of fertilizers which number includes all the registered brands which were found on sale. These together with samples submitted by purchasers or others interested may be classified as follows: CLASSIFICATION OF FERTILIZERS ANALYZED. I. Containing Nitrogen as the chief active ingredient: Nitrate of Soda.. Sulphate of Ammonia Castor Pomace.. Cottonseed Meal. Linseed Meal... Raw Rock Phosphate.. Precipitated Bone Phosphate. II. Containing Phosphoric Acid as the chief active ingredient: Dissolved Rock Phosphate or Acid Phosphate III. Containing Potash as the chief ingredient: Carbonate of Potash. Muriate of Potash. Sulphate of Potash. Double Sulphate of Potash and Magnesia... IV. Containing Nitrogen and Potash: Nitrate of Potash... Nitrate of Potash and Soda. V. Containing Nitrogen and Phosphoric Acid: Tankage.. Ground Bone. 40 VI. Mixed Fertilizers: Containing Phosphoric Acid and Potash.... Special and Home Mixtures. 23 299 8888 VII. Miscellaneous fertilizers, amendments, waste products, etc.: I. RAW MATERIALS CHIEFLY VALUABLE FOR NITROGEN. NITRATE OF SODA. Pure nitrate of soda contains 16.47 per cent of nitrogen. Commercial grades of this salt generally contain from 15 to 16 per cent of nitrogen which is equivalent to from 18.2 to 19.5 ammonia or 91 to 97 per cent nitrate of soda. Twenty-three samples were examined and the results are given in Table I. Sample 23039 was considerably under guaranty and a second sample, 23306, from the same lot was also deficient. Sample 23013 was found to be deficient but a second sample of the same brand taken from a different source was well over the guaranty. Two samples, Nos. 23204 and 23205, submitted by purchasers, were found to be considerably under the guaranty of 15 per cent nitrogen. The salt was red-brown in color and contained much insoluble matter. The Apothecaries Hall Company, who distributed this chemical, sold in original bags as received by them. They investigated and found that the low grade product constituted but a small part of their entire stock; they were allowed a rebate by the importers from whom they bought and reimbursed their customers accordingly. Nitrogen from this source has cost from 20.6 to 28.9 cents per pound, the average being about 23.3 cents. Ton prices have ranged from $62.50 to $75.00. We are uncertain about the guaranties on samples 21899, 21900, 21901 and 21902. The jobbers claim the goods were guaranteed 15 per cent nitrogen, while the information submitted by the purchasers is that the salt was supposed to analyze 95 per cent nitrate of soda, which is about 15.60 per cent nitrogen. We have no information as to whether any adjustment was made or asked for. 23067 F. S.

Ten samples were examined and the results are given in Table II. Pure ammonium sulphate contains 21.2 per cent of nitrogen, but the commercial grades usually contain about 20.5 per cent, which is equivalent to about 25 per cent of ammonia or about 97 per cent of ammonium sulphate. As sold in the State this year this salt has contained from 20.2 to 20.9 per cent of nitrogen. Sample 23240 was a second sample drawn as a check on sample 23146; both were substantially up to the guaranty. Sample 161 was a check on 23011 and exceeded the guaranty, whereas the first sample was slightly low. Sample 23395 showed a shortage of 0.33 per cent nitrogen. This was a small lot and was not resampled. According to prices quoted, the cost per pound of nitrogen has ranged from 9.8 to 19.3 cents, the average being 16.6 cents; this is $3.32 per unit of nitrogen, or $2.78 per unit of ammonia. prices have ranged from $40.00 to $79.00.
