Sufficient supply of nitrogen (N) plays a key role in corn productivity and profitability. Excess nitrogen application wastes farmers’ money, increases the risk of groundwater and surface water contamination, and contributes to greenhouse gas emissions. Evaluating N management is important for farmers to fine tune N management practices to achieve optimum corn yield and environmental sustainability. The end-of-season corn stalk nitrate-nitrogen test and corn yield are well correlated, which provides the basis for post-harvest evaluation of N sufficiency level.
