Giovani Preza Fontes - Cereal Rye Ahead of Corn: Impacts on Yield and N Losses

Giovani Preza Fontes is an Assistant Professor and Extension Field Crop Specialist with the University of Illinois. In this presentation, Preza Fontes discusses a three-year study on reducing nitrate leaching using in-season split nitrogen application and cereal rye cover crops. The study finds that these practices significantly reduce nitrate leaching without negatively impacting corn yields when managed properly.
