20 pages. This archival publication may not reflect current scientific knowledge or recommendations. Current information available from the University of Minnesota Extension: https://www.extension.umn.edu.Tillage recommendations for corn and soybeans in south central Minnesota are presented with background research results for tillage systems and associated phosphorus and nitrogen management. Research and recommendations address no-till, strip-till, deep zone-till, ridge-till, spring single-pass (disk or field cultivator), chisel plow, and moldboard plow, as well as rotations among tillage systems. Management factors, including crop rotation, soil characteristics, nutrient management, weed management, and conservation structures are also discussed in relation to tillage systems.The authors sincerely appreciate and thank the Minnesota Pollution Control Agency, Fluid Fertilizer Foundation, Potash and Phosphate Institute – Foundation for Agronomic Research, and John Deere Company for their financial support of the research contained in and production of this bulletin
