功效 / Functions

正丁基硫代磷酰三胺（NBPT）是目前世界上最有效的土壤脲酶抑制剂之一。

N-(n-Butyl)thiophosphoric Triamide (NBPT) is one of the most effective soil urease inhibitors in the world. Nitrogen fertilizer is the most widely used and important type of fertilizer in modern agriculture, of which urea accounts for more than 2/3 of the total nitrogen fertilizer. However, urea is quickly decomposed by soil urease, which is ubiquitous in the environment, resulting in a large waste of nitrogen fertilizer resources, thereby increasing the cost of crop production and bringing about a series of problems such as soil compaction and environmental pollution. Adding urease inhibitors to nitrogen fertilizer is a modern agricultural technology developed and promoted internationally in recent years. For example, adding NBPT to urea can make a stable fertilizer. NBPT can inhibit urease activity, slow down the rate of urea hydrolysis, produce a slow-release effect of nitrogen fertilizer, effectively reduce the waste of nitrogen fertilizer, synchronize soil fertilizer supply and crop fertilizer demand, thereby greatly improving the effective utilization rate of nitrogen fertilizer, increasing crop yield and protein content, reducing secondary topdressing, and reducing air pollution and nitrogen leaching caused by ammonia volatilization. At the same time, NBPT itself is non-toxic and has no side effects on the soil. It is naturally degraded into ammonia and phosphorus in the soil and can also be absorbed by crop roots as a fertilizer.

应用 / Applications

尿激酶活性抑制剂, 氮肥增效剂，硝化抑制剂，肥料添加剂。

Urokinase activity inhibitor, nitrogen fertilizer synergist, nitrification inhibitor, fertilizer additive.

N-(n-Butyl)thiophosphoric triamide (NBPT) is a potent soil urease inhibitor. As a soil urease inhibitor, n-butyl triamine thiophosphate is highly efficient, non-toxic, has no side effects on soil, and is naturally decomposed into ammonia and ammonium phosphate in soil.
