Abstract

Nitrogen is one of the major elements essential for plant growth. It is the element most prone to depletion by cultivation and is usually found deficient in soils. In successful farming the problem of nitrogen supply is of special importance because plants need it in large amounts, it is fairly expensive to supply, and it is easily lost from the soil.
