Ag Engineering/Agronomy, Central Iowa and BioCentury Research Farms
Farmers in central and north central Iowa are often criticized for low adoption of no-tillage. No-tillage is often faulted with cooler, wetter soils and subsequently reduced yields. An alternative to conventional tillage and no-tillage systems is strip tillage where the benefits of both may be combined.
