Abstract
Corn belt corn and soybean producers are increasingly challenged to maximize crop production while addressing the contributions farm practices make to the Gulf of Mexico hypoxia. Based on the need for nitrate-nitrogen (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 ongoing field research and demonstration project is evaluating various promising N management methods and technologies by documenting the nitrate-N export and crop yield from various systems. This is a summary of four years of crop yield data.
