EFFECT OF CHEMICAL INHIBITION OF NITRIFICATION ON PHOSPHORUS ABSORPTION BY WHEAT

Abstract

Wheat was grown in a loam soil that had been treated with N serve, a nitrification inhibitor, and dressed with N and P fertilizers.With the inhibitor, NH₄-N accumulated in the soil but NO₃-N accumulated where none was used. Uptake of N was less when nitrification was inhibited but uptake of P was greater.
