A nitrification inhibitor temporarily delays the conversion of ammonium to nitrate. It is used to prevent nitrate losses should weather conditions conducive to N loss occur. Therefore, a nitrification inhibitor should be considering a risk management tool, not a yield enhancement tool. Several recent studies in Wisconsin have evaluated the nitrification inhibitor Instinct or Instinct II with spring or fall applied manure.
