Vertical-tillage improves planting conditions, preserves conservation

University of Wisconsin's Kevan Klingberg and Dennis Frame, in cooperation with Discovery Farms' Curt Weisenbeck, looked at the impact of shallow vertical-tillage on soil disturbance and crop residue. They found that just one pass with a vertical-tillage tool will leave 70 to 80 percent of previous corn residue in place and 80 percent of last year's corn roots.
