“And the quantity of nitrogen, phosphoric acid, and potash found in the manure is determined, other things being equal, by the quantity of the nitrogen, phosphoric acid, and potash contained in the food consumed by the animals making the manure.” CHAPTER XII. FOODS WHICH MAKE RICH MANURE. The amount of nitrogen, phosphoric acid, and potash, contained in different foods, has been accurately determined by many able and reliable chemists. The following table was prepared by Dr. J. B. Lawes, of Rothamsted, England, and was first published in this country in the “Genesee Farmer,” for May, 1860. Since then, it has been repeatedly published in nearly all the leading agricultural journals of the world, and has given rise to much discussion. The following is the table, with some recent additions: TD: Total dry matter. TM: Total mineral matter (ash). Ph: Phosphoric acid reckoned as phosphate of lime. P: Potash. N: Nitrogen. V: Value of manure in dollars and cents from 1 ton (2,000 lbs.) of food. -----------------------+----------------------------------+------- | Per Cent. | +------+------+------+------+------+ | TD | TM | Ph | P | N | V -----------------------+------+------+------+------+------+------- 1.
