AMES, Iowa — Iowa Learning Farms and the Sac Soil and Water Conservation District are hosting a field day on Tuesday, June 5 on the Dean Tiefenthaler farm, rural Breda, beginning at 6 p.m. The field day will focus on strip-tillage as a conservation farming practice. The field day includes a complimentary evening meal served by Leon and Margie Boes. The event is free and the public is invited to attend.
The evening will begin at Dean Tiefenthaler’s farm, located one mile west of Breda, northeast of the intersection of county road E-16 (120th Street) and Falcon Ave. Tiefenthaler will share his experience in adopting strip-tillage and how he is succeeding with this practice. Strip-tillage marries the best aspects of conventional tillage with the benefits of no-till. Before planting (fall post-harvest, or spring pre-plant) a strip-tillage implement creates strips of tilled soil. Surface residue is left undisturbed between the tilled strips. Corn or soybeans are planted into the tilled soil strips, which warm and dry faster than the rest of the field. This practice offers better water infiltration, improved soil structure, and potential for reduced fuel, machinery and other crop input costs.
Attendees then will move to the shelter at Breda City Park for the rest of the event. Following the meal at the shelter, hear about the efforts to improve Black Hawk Lake and reduce the sediment losses from farmland into the lake. Representatives from Schenkelberg Implement Company, Brokaw Supply and Crop Production Services Inc. will be on hand to discuss precision agriculture, strip-till, nutrient management and soil sampling. Breda City Park is located at the corner of Park and N. 2nd Streets in the northeast area of town.
The Lil’ Conservation Station also will be at the event. The Conservation Station is a mobile learning center that travels across the state teaching all Iowans how they can help to improve water quality and keep Iowa’s soils in place—building a Culture of Conservation. The Conservation Station’s rainfall simulator demonstrates the effects of rainfall on different land scenarios. Water runoff and subsurface drainage are collected in clear jars that show what is coming off the land including heavily tilled soil, minimum tillage and pervious pavement.
Iowa Learning Farms takes a grassroots approach, offering innovative ways to help all Iowans have an active role in keeping the state’s natural resources healthy and not take them for granted. A goal of Iowa Learning Farms is to build a culture of conservation, encouraging the adoption of residue management and conservation practices. Farmers, researchers and ILF team members are working together to identify and implement the best in-field management practices that increase water and soil quality while remaining profitable.

Iowa Learning Farms is a partnership of the Iowa Department of Agriculture and Land Stewardship, Iowa State University Extension and Outreach, Leopold Center for Sustainable Agriculture, Iowa Natural Resources Conservation Service and Iowa Department of Natural Resources (USEPA section 319); in cooperation with Conservation Districts of Iowa, the Iowa Farm Bureau and the Iowa Water Center.
