Nitrogen Fertilization of Corn Grown with a Cover CropIowa State Research Farm Progress Reports
FarmNortheast Research and Demonstration Farm
Extension NumberRFR A1064
AbstractObjectives of this project were to study corn nitrogen (N) fertilization requirement and corn-soybean yield response when grown in a rye cover cropping 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 multiple research farms, with the intent for comparison of with and without a cover crop system across varying soil and climatic conditions in Iowa.
