Join these farming neighbors to learn about their goals for cover cropping, which include soil improvement, grazing forage, primary crop health and yield, and weed control. Alison Robertson, a professor of plant pathology and microbiology at ISU, will also be on hand to discuss her lab team’s research on the implications for crop disease management when using cover crops. See planter set-up for no-till planting into cover crops and live cover crop seeding demos.
