High-grade Fertilizers








A high-grade fertilizer is not necessarily a
high-priced one. What we want in a fertilizer is a high content of the
plant-food needed, together with desirable availability. If only
phosphoric acid is wanted, a 14 per cent, or 16 per cent, acid
phosphate is high-grade because it contains as many pounds of available
phosphoric acid in a ton as the public can buy in a large way. A 10 per
cent acid phosphate is low-grade. The effort is to escape paying
freight, and other cost of handling, on waste material as far as
possible. Generally speaking, the higher the percentages of plant-food
in a fertilizer, the cheaper per pound is the plant-food. A low-grade
fertilizer rarely fails to be an expensive one because the expense of
handling adds unduly to the price per pound of the small content of
plant-food.
