RULE FOR CALCULATING VALUATION OF FERTILIZERS. The commercial valuation will be accurate enough as a means of comparison if the following rule is adopted: Multiply 3.5 by the percentage of nitrogen. Multiply 0.8 by the percentage of available phosphoric acid. Multiply 0.4 by the percentage of insoluble phosphoric acid. Multiply 1.0 by the percentage of potash. The sum of these four products will be the commercial valuation per ton on the basis taken. Illustration. The table of analyses shows a certain fertilizer to have the following composition: Nitrogen 2.00 per cent; Available phosphoric acid 8.50 per cent; Insoluble phosphoric acid 3.50 per cent; Potash 3.25 per cent. The valuation in this case will be computed thus: Nitrogen, 3.5 X 2.00, $7 00 680 Available phosphoric acid, .8 X 8.50, 0.4 X 3.50, I 40 Valuation per ton, $18 45 Since this rule assumes all the nitrogen to be organic and all the potash to be in the form of the sulphate, it is evident that the valuations thus calculated must not be taken as the only guide in the choice of a fertilizer. At best the valuations can only serve to show the approximate cost of the several ingredients contained in the fertilizer in question. In every case the farmer should consider the needs of his soil before he begins to consider the cost. In many instances a little careful experimenting will show him that materials containing either nitrogen, potash, or phosphoric acid alone will serve his purpose as fully as a “complete fertilizer," in which he must pay for all three constituents, whether needed or not. |
