Inhibitor Urea 46 is designed to inhibit the activity of “urease,” a key enzyme in the metabolic pathway of soil bacteria. When urea granules are deposited on the soil surface, they must be dissolved by water to be absorbed into the soil. If bacteria on the soil surface reach urea before it absorbs into the soil, the bacteria convert urea into ammonia gas which immediately volatilizes into the atmosphere. Inhibitor Urea 46 containing NBPT prevents this process from taking place and enables its uptake as an intact molecule by the plant roots.
Inhibitor Urea 46 maximizes the efficiency of urea by impeding ammonia volatilization, nitrate leaching, and the rapid hydrolysis of urea.
