Research results from a study led by Extension specialist Fabian Fernandez at the Rosholt Research Farm in Westport, Minnesota show data from 2016 to 2019 for two cover crop systems: winter rye and Kura clover living mulch. The farm is in the Bonanza Valley and has an irrigation system. Read more in this press release from the University of Minnesota.

Balancing the supply and demand of nitrogen (N) in crop production is challenging. In most cases, application of N fertilizer is needed to ensure that adequate N is available to corn. Nitrogen that is not taken up by plants can be lost from cropping systems as nitrate through leaching or runoff, according to this article from the University of Minnesota Extension.
