The World War stimulated research on the production of synthetic nitrogenous compounds and after the war, this activity was transferred to the production of synthetic nitrogenous fertilizers. Today these fertilizers are rapidly coming into practical use and a knowledge of their effects on soil conditions is essential to a proper determination of their agricultural value and economic significance.
