Abstract

Corn belt corn and soybean producers increasingly are challenged to maximize crop production while addressing the contributions farm practices make to the Gulf of Mexico hypoxia. Based on the need for nitrate-N reductions to meet water quality goals, new management practices are needed to reduce nitrate-N losses at minimal cost and maximum economic benefits. This three-year field research and demonstration project evaluates various promising N management methods and technologies by documenting the nitrate-N export and crop yield.
