The goal of this project is to evaluate the optimal time to inter-seed cover crops while simultaneously applying nitrogen. While this practice has become more popular, very little field-scale research has been conducted to determine how early we can inter-seed cover crops to maximize their benefit while still maintaining yield. This project will evaluate how different inter-seeding dates can affect weed control, cover crop production and corn yield. Identifying these things can improve farmer’s efficiency as well as maximize cover crop production. Increased cover crop production has been proven to reduce potential nitrate leaching, prevent erosion, increase organic matter and bring overall greater soil heath and sustainability to our agriculture system.
