This fall, field observations with significant amounts of intensive tillage and residue removal provide an opportunity to rethink such practices by considering research proven practices such as no-tillage (NT) and strip-tillage (ST), which have demonstrated their effectiveness in many parts of the state and across the Midwest. Many studies from the Midwest and elsewhere have documented the economic benefits of NT and ST for both corn and soybean, where the conventional tillage input cost was greater than that of NT and ST by $15-25/acre in a study covering 14 years of tillage and crop rotations in Iowa.
