Modeling the economic and environmental effects of corn nitrogen management strategies in Illinois
Field Crops Research(2021)
Abstract
•Eco-efficient use of Nitrogen in corn involves improving Management Strategies.•Crop models can compare nitrogen management strategies in corn farming scenarios.•Information sources, prediction models, and fertilizer application were compared.•Strategies that use data from regional trials achieved the highest eco-efficiency.•Such a strategy would reduce the mean N-leaching by 12.7% without changing profits.
