Use of NBPT and associated technologies in corn

In the corn culture, the use of urease inhibitors such as NBPT (N (n butyl) thiophosphoric triamide) and other associated technologies are gaining ground as a strategy to improve the efficiency of nitrogen fertilization and reduce Nitrogen (N) losses. Nitrogen is a key nutrient for the yield of corn crops, and its losses — through volatilization, leaching, or denitrification — compromise the efficiency of the investment and increase the environmental impact. Technologies that allow reducing these losses and ensuring that more applied N is effectively absorbed by the plant can generate significant gains in productivity and sustainability. Functioning of NBPT and technological basis NBPT acts by inhibiting the soil urease enzyme, which catalyzes the hydrolysis of urea applied to ammonia (NH3) — the initial step that leads to volatilization when the fertilizer remains on the soil surface without incorporation. Studies indicate that “the application of urea with urease inhibitor ...
