Nitrous oxide formation through denitrification is commonly linked to excess water due to soil pores blocked by water leading to anaerobic soil conditions conducive for nitrous oxide formation. However, for soils with poor drainage like high clay soils of the Red River Valley, North Dakota, loss of nitrogen fertilizer through denitrification was observed even under a dry growing season (Fig. 1). In 2012, significant precipitation deficits from May through August resulted in large areas of the Great Plains in drought conditions. Denitrification loss of nitrogen was determined for Urea-N applications with and without addition of the nitrification inhibitor, nitrapyrin, for corn and sugarbeet, prime consumers of nitrogenous fertilizers.
