Abstract
This project is designed to study the nitrogen (N) fertilization needs in continuous corn (C-C) and corn rotated with soybeans(C-S) as influenced by location and climate. Multiple rates of N fertilizer are spring applied, with the intent to measure the yield response to N fertilization within each rotation on a yearly basis at multiple sites across Iowa. This allows the determination of N requirements for each rotation practice, differences that exist between the two rotations, responses to N applied across different soils and climatic conditions, and evaluation of tools used to adjust the N application.
