Fertilizers

Categories: THE COWPEA

The light soils of Maryland, New Jersey, and the southern

states are not naturally rich in phosphoric acid or potash. The cowpea

can draw its nitrogen from the air, but on all thin land it pays to use

200 to 300 pounds of acid phosphate and 50 pounds of muriate of potash

per acre for this crop which should have a luxuriant growth for the

soil's benefit. Such use of fertilizers is more profitable than their

use on the crop which follows.
