University of Wisconsin looks at strip tillage for soybeans
A University of Wisconsin study is gathering data about strip tillage in soybeans.
Graduate student Derek Potratz with the UW Madison agronomy team tells Brownfield there is a lot of data on strip tillage for corn, but not much information on using strip tillage for soybeans, so that’s where his focus has been. He tells Brownfield the study, “is to determine where interactions might be occurring between strip tillage and different management uses like row spacing or fertilizer placement as well as fungicide use.”
Potratz says he thinks of strip tillage much like an insurance policy. “In adverse conditions and in poorer years, you’re going to see a benefit out of strip tillage however in an average year, an everyday year, a good year even, you’re not going to see a yield drag from strip tillage, so I think it’s a good way to go if you need to have some type of tillage in your system.”
He says their studies compared strip tillage to no-till, and he says producers won’t see as large of an effect in lighter soils because of less aggregate stability and different soil warming characteristics.
