N-(N-butyl)-thiophosphoric Triamide(NBPT) is currently one of the most effective urease inhibitors in the world. Nitrogen fertilizer is the most widely and important fertilizer in modern agriculture, and urea accounts for more than 2/3 of the total nitrogen fertilizer. Under normal circumstances, urea is quickly decomposed by urease in the soil, the utilization rate of urea is usually only 30%-40%, so the fertilizer effect period is short. This not only a wastes of nitrogen fertilizer resources, increases planting costs, but also brings a series of problems such as soil knots and environmental pollution.
Urease inhibitors can inhibit the activity of soil urease, which can inhibit and slow nitrogen release. The use of soil urease inhibitors can effectively slow down the process of urea decomposition into ammonia, reduce the concentration of NH4+ and NH3 in the soil, reduce waste. and at the same time extend the diffusion time of nitrogen fertilizer at the fertilization point. So that the fertilizer supply of the soil and the fertilizer demand of the crop are synchronized. Thereby increasing the effective utilization rate of nitrogen fertilizer by 30%-40%.
