Impact of 4R Management on Crop Production on Tile Drainage Plots

Authors: ,


Corn belt corn and soybean producers increasingly are challenged to maximize crop production while addressing the contributions farm practices make to Gulf hypoxia. Based on the need for nitrate-N reductions in surface water systems to meet water quality goals, new management practices are needed to reduce nitrate-N losses at minimal cost and maximum economic benefits. This 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. Due to the dry conditions in 2021 and 2022 there were few water samples.
