Fertilizers. Determination of N-(n-Butyl)thiophosphoric acid triamide (NBPT) and N-(n-Propyl)thiophosphoric acid triamide (NPPT). Method using high-performance liquid chromatography (HPLC) Ingestion-build-181247 for certifications (schemes and bodies)What is BS EN 16651 NBPT and NPPT in fertilizers about? BS EN 16651 is a standard that serves technical specifications for determining NBPT and NPPT in fertilizers, ensuring fertilizer use efficiency and protection against ammonia volatilization in agricultural applications. BS EN 16651 specifies the method for the quantitative determination of the urease inhibitors N (n Butyl) thiophosphoric acid triamide (NBPT, CAS No. 94317 64 3) and N (n Propyl)
