    Nitrogen Fertilization of Corn Grown with a Cover Crop

    Authors: , ,

Abstract

Objectives of this project were to study corn nitrogen (N) fertilization requirement and corn-soybean yield response when grown in a cover crop system. Multiple rates of N fertilizer are applied, with measurement of corn yield response to applied N and soybean yield with and without a fall planted winter rye cover crop. The study is being conducted at several research farms, with the intent for study across multiple years to allow comparison of with and without a cover crop system across varying soil and climatic conditions.
