Is interseeding of cover crops into corn a viable management practice?

For farmers interested in planting cover crops for erosion, nutrient, and soil health benefits, getting cover crops established in the corn or soybean phases of their crop rotation can be difficult. Drill seeding cover crops when corn is in the mid-vegetive growth stages has been proposed as a management practice. Concerns arise around the competition of water and nutrients – essentially, is the cover crop acting like a weed. Research conducted at the Arlington Agricultural Research Station in 2014 showed that planting cover crops did not reduce corn yield. Full details on the research can be found here. Findings from the 2015 field trial will be presented at the 2015 Soil, Water, and Nutrient Management Meetings.
