Research

Research is focused on identifying and understanding agronomic practices that increase crop productivity, profitability, and sustainability of corn‐based cropping systems. This is done through field research conducted at university research and outreach centers and on working farms, which serves as the foundation for educational programs for agricultural professionals and farmers.
