Francis Thicke and Kathleen Delate
Friday Session II
Tillage has been the go-to to manage weeds in organic row crops. Yet tillage can negatively impact soil health. We’ll talk about ways to offset the negative effects of tillage and methods that greatly lessen the need for tillage. We’ll also share the latest research on planning, planting and managing rolled or mowed rye or other cover crops that improve soil health, lessen erosion and even provide some pest and disease protection for the cash crop.
Francis Thicke has a Ph.D. in soil fertility and has served as National Program Leader for Soil Science for the USDA-Extension Service in Washington, D.C. He and his wife own and operate an 80-cow, grass-based, organic dairy near Fairfield, Iowa.
Kathleen Delate is an Iowa State University professor in the departments of Horticulture and Agronomy, where she is responsible for research, extension, and teaching in organic agriculture. She was awarded the first faculty position in organic agriculture at a U.S. Land Grant University in 1997.
