NBPT is an advanced urease inhibitor with excellent effect, wide application and high cost performance in the world. At present, it is widely used in the United States, Brazil, Germany and other countries. The half-life after entering the soil is 7-8 days, which will not affect the next crop. The final decomposition products are mainly ammonium, sulfate, phosphate, etc., which have no negative effects on soil, microorganisms, people and animals, water bodies, etc., and have passed the full detection of the US Food Safety Administration (FDA).
Efficacy: NBPT can inhibit urease activity in soil, effectively slow down the process of urea hydrolysis to ammonia, reduce nitrogen volatilization, improve the utilization rate of nitrogen fertilizer, prolong fertilizer efficiency, and reduce the toxicity of high concentration nitrogen to crop seeds and seedlings. Application: added to urea or urea-containing fertilizer to produce stable urea, stable mixed fertilizer, water-soluble fertilizer, etc. Addition amount: NBPT (in pure form) is added at 0.09%-0.2% of amide nitrogen content in fertilizer or at 4/10000 to 9/10000 of urea.
