Cover crops incorporated into a continuous no-till field crop rotation can produce enough nitrogen to complement, or in some cases, replace corn nitrogen fertilizer applications, according to long-term Ohio State University Extension research.


Seven years of research at Ohio State University's South Centers at Piketon have found that cover crops such as cow pea or winter pea worked into a corn/soybean/wheat rotation can produce enough nitrogen to support at least 150 bushels of corn per acre.


The findings indicate farmers can save money on spring nitrogen fertilizer applications while reaping the environmental benefits of cover crops.
