NBPT, N-(N-BUTYL)THIOPHOSPHORIC TRIAMIDE is the most advanced, the best, the most widely applied and cost-effective urease inhibitor in the world. 

On the one hand, NBPT can effectively slow down the enzymatic hydrolysis process of nitrogen fertilizer decomposition into nitrogen, reduce waste.

At the same time NBPT extend the diffusion time of nitrogen fertilizer at the fertilization point, thereby increasing the effective utilization rate of nitrogen fertilizer by 30-40%, and the fertilizer efficiency can be increased from 50 days to 120 days. 
Almost covers the entire growth period, it is completely possible not to use secondary top dressing.

The half-life of 7-8 days after entering the soil will not affect the next crop. Final catabolite is mainly ammonium, sulfate radical, phosphate radical etc., which has no adverse effects on soil, microorganisms, humans, animals and water. It has been tested by the US Food and Safety Administration (FDA).
