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

Authors: Matthew J. Helmers (Iowa State University) , Carl Pederson (Iowa State University)

Abstract

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.
