Description

Increases in nitrogen prices and environmental pressures have caused many corn producers to reevaluate nitrogen (N) management to determine if they can improve use efficiency. One potential avenue of improving N use efficiency is to allow applied N the ability to avoid volatilization losses when utilizing urea-based fertilizers and to lengthen the amount of time ammonium is present since it is much less susceptible to loss than nitrate. This obviously means considering either a urease inhibitor or a nitrification inhibitor. The goal of this proceedings article is to discuss various urease and nitrification inhibitors, examine modes of action, and evaluate agronomic utility.
