Abstract

All cropping systems require fertilizer inputs to maintain crop yields. However, excess fertilizer, especially nitrogen (N) and phosphorus (P), can increase problems with water quality. Micronutrients are required for all crops. Starter fertilizer has been shown to occasionally increase corn yields, but is a lesser tested practice in soybean. 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 and practices on crop yield.
