Authors: Camila Martins (Iowa State University) , John Lundvall (Iowa State University) , John E. Sawyer (Iowa State University)

Abstract

This study was designed to investigate nitrogen (N) response in cereal rye seed production, influence of a red clover cover crop on corn N fertilization requirement, and the overall integrated-production system on soil nitrate-N. The study was conducted at two locations. This report summarizes the two-year (2019-20) corn crop results.
