Is Nitrogen Fixation Oversold with Legume Cover Crops?

December 16, 2016

One expected benefit of using legumes as a cover crop is to provide a source of nitrogen (N) to the cropping system. However, when legumes are included in mixtures with grasses and broadleaves for a relatively short growing period, the amount of actual fixed N may be relatively low.
