In addition to preparing the soil for planting, tillage can be an effective strategy for weed management. During a field trial, blue chalk was applied to the soil surface in areas where a tillage pass was made with a vertical tillage (VT) tool at a 3 degree, 5 degree and 9 degree gang angle setting.
