On-Farm Corn and Soybean Fertilizer Trials

By Jim Fawcett, Josh Sievers, Joel DeJong and Jim Rogers

Abstract

All cropping systems require fertilizer inputs to maintain crop yields. However, excess fertilizer, especially nitrogen (N) and phosphorus, can increase problems with water quality. It is important for farmers to use the appropriate rates and methods of fertilizer application to optimize yields and minimize the impact on the environment. The purpose of these trials was to investigate the effect of various fertilizer practices on crop yield
