Sarah Moore, M. Samantha Wells, Melissa Wilson, Russ Gesch, and Roger Becker Pennycress at physiological maturity Overview: Thirty-seven percent of sweetcorn in the US is produced in the upper Midwest. In order to meet quality standards, sweetcorn requires high nitrogen fertilization. It is also harvested as a fresh vegetable rather than a grain, meaning there is a large quantity of nitrogen in the residue that is left on the field after harvest. As a result, sweetcorn systems are particularly susceptible to nitrogen loss. Planting a cover crop after sweetcorn can help to keep this nitrogen in the field and out of waterways. Additionally, sweetcorn is harvested earlier than grain corn, allowing more time in the fall for a cover crop to establish and grow. However, cover crop adoption is low in the upper Midwest due to a lack of incentives. Outside of forages, such opportunities for cover crop profits are limited.
