2017-12-27 back

Product Description

NBPT, N-(N-butyl) thiophosphoric triamide, is a white crystal powder.

As a soil urease inhibitor, NBPT has the effect of inhibiting urea hydrolysis and slow releasing nitrogen. It inhibits the hydrolysis process of urea into ammonia, and increases the use efficiency by at least 30%. The nitrogen availability can be extended from 50 days to nearly 120 days. The product is highly-effective and non-toxic. It can eliminate the toxic effects of ammonia on seed germination and seedling growth, thus it is an excellent soil urease inhibitor. NBPT is used for urea-based nitrogen fertilizers, taking effect in almost the whole crop growth period without top-dressing.
