N-(n-Butyl)thiophosphoric triamide (NBPT) is the organophosphorus compound with the formula SP(NH₂)₂(NHC₄H₉). A white solid, NBPT is an "enhanced efficiency fertilizer", intended to limit the release of nitrogen-containing gases following fertilization.^[1] Regarding its chemical structure, the molecule features tetrahedral phosphorus bonded to sulfur and three amido groups.

Use

NBPT functions as an inhibitor of the enzyme urease.^[2] Urease, pervasive in soil microorganisms, converts urea into ammonia, which is susceptible to volatilization if produced faster than it can be utilized by plants. Approximately 0.5% by weight NBPT is mixed with the urea.^[3]
