Title: Dual purpose urease and nitrification inhibitors

Patent ·
OSTI ID:6645219

This patent describes a method for inhibiting the nitrification of ammonium nitrogen resulting from the inclusion of ammonia or ammonium-containing fertilizers to nitrite and nitrate at a situs, the situs including soil systems. It comprises: exposing soil containing nitrifying organisms at the situs to relatively small predetermined amounts of thiophosphoryl triamide. The method is characterized by the fact that loss from the situs of fertilizer nitrogen values by leaching and denitrification therefrom and the resulting potential for groundwater pollution by the leaching and atmospheric pollution by the denitrification is eliminated or substantially reduced.
