Reducing the intensity of tillage can help improve the soil in many ways. Maintaining more residue on the surface reduces runoff and erosion, while the reduction in soil disturbance allows for earthworm holes and old root channels to rapidly conduct water from intense rainstorms into the soil. There are many choices of reduced tillage systems, and equipment is available to help farmers succeed. Using cover crops along with reduced tillage has been found to be a winning combination, providing surface cover rapidly and helping to control weeds.
