Nitrous oxide emissions following split fertilizer application on winter wheat grown on Mollisols of Southern Alberta, Canada

Synthetic fertilizer-induced nitrous oxide (N2O) emissions contribute to climate change. Enhanced efficiency fertilizers (EEFs) may reduce soil N2O emissions compared to conventional fertilizers like urea-ammonium-nitrate (“UAN”) and urea by better matching fertilizer N supply with plant N demand. This study tested whether three liquid EEFs (a nitrification inhibitor, “NI”, a urease inhibitor, “UI”, and a urease and nitrification inhibitor, “UI...
