N-(n-Butyl)thiophosphoric triamide Cas 94317-64-3
It is currently one of the most effective soil urease inhibitors. As a soil nitrogen fertilizer inhibitor, NBPT is highly efficient, non-toxic, has no side effects on soil, and naturally degrades into ammonia and phosphorus in the soil. It can also be absorbed as fertilizer by crop roots and reduces the toxicity of ammonia to seed germination and seedling growth. The effect is an excellent soil nitrogen fertilizer enzyme inhibitor.
