N-(n-butyl)-thiophosphoricTriamide(NBPT) Urease inhibitors can inhibit the activity ofsoil urease, which can inhibit and slownitrogen release. The use of soil ureaseinhibitors can effectively slow down theprocess of urea decomposition intoammonia, reduce the concentration ofNH4+ and NH3 in the soil, reduce waste,and at the same time Extend the diffusiontime of nitrogen fertilizer at thefertilization point, so that the fertilizersupply of the soil and the fertilizerdemand of the crop are synchronizedThereby increasing the effective utilizationrate of nitrogen fertilizer by 30%-40%.
