Early season cover crop interseeding in corn

Article on MN Crop news from M. Scott Wells, Alex Hard, Eric Ristau, and David Nicolai – UMN Cover Crop Team

As many are aware, cover crops can provide growers with erosion control, reduce offsite movement of nutrients, support the development of soil organic matter, and in some cases provide additional revenue streams (e.g. forages, oilseeds). Even though cover crops offer several opportunities to growers who utilize them, historical, adoption has been marginal. It is estimated that less than 2% of the agricultural land in MN utilizes cover crops at some point in the rotation. There are several reasons for low adoption rates, but the most obvious reason is associated with the shorter growing season when compared to our neighbors in the South. The reduced growing season offers many challenges to successful integration of cover crops; however, there are new technologies that have the potential to overcome these challenges.
