Analyses of Various Chemical Fertilizer and Related Materials Dissolved Bone-Black

This material is a superphosphate prepared by treating refuse bone-black from sugar refineries with oil of vitriol, which renders nearly all the phosphoric acid soluble in water.

Sulfate of Ammonia

This article, now manufactured on a large scale as a by-product of gas-works, usually contains over 20 per cent of nitrogen, the equivalent of from 94 to 97 per cent of sulfate of ammonia. The rest is chiefly moisture. Nitrogen........20.02 Equivalent ammonia .... 24.30

Sulfate of Potash. (Two samples)

The double sulfate of potash and magnesia is usually sold as "sulfate of potash."

Sulfate of Magnesia

Moisture at 100° C.....29.01 Sulfuric acid .......30.35

Magnesium oxide.....15.87 Insoluble matter.....6.29

Nitrate of Soda

Nitrate of soda is mined in Chile and purified there before shipment. It usually contains about 16 per cent of nitrogen, equivalent to 97 per cent of pure nitrate of soda. It contains, besides, a little salt and some moisture.

Moisture........0.35 Sulfate of soda......0.21

Salt (sodium chloride) .... 0.23 Pure nitrate of soda .... 99.21

Muriate of Potash. (Two samples)

Commercial muriate of potash consists of about 80 per cent of muriate of potash (potassium chloride) ; 15 per cent or more of common salt (sodium chloride), and 4 per cent or more of water.
