Southeast Research and Demonstration Farm
This project at the Southeast Research and Demonstration Farm was a four-year project designed to study the yield effects of vertical tillage systems compared with conventional and no-till systems in corn and soybeans. There has been increasing interest in vertical tillage systems in recent years, so the goal of this project was to compile information on these various cropping systems.
