Seasonal and Rotational Influences on Corn Nitrogen Fertilization

Authors: ,


This project was designed to study the nitrogen (N) fertilization needs in continuous corn (CC) and corn rotated with soybean (CS) as influenced by location and climate. Multiple rates of N fertilizer were spring-applied, with the intent to measure yield response to N within each rotation on a yearly basis for multiple years at multiple sites across Iowa.
