Seasonal and Rotational Influences on Corn Nitrogen Fertilization

Authors: John Sawyer (Iowa State University) , John Lundvall (Iowa State University)

Abstract

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 springapplied, with the intent to measure yield response to N within each rotation on a yearly basis for multiple years at multiple sites across Iowa.
