  7. Conservation Tillage • Conservation-tillage farming: method of soil cultivation that leaves the previous year's crop residue on fields before & after planting the next crop • No-till: involve planting crops directly into residue that either hasn't been tilled at all • Minimum tillage: some residue has been removed, but at least 30 to 70% remains

  8. No Till & Minimum Tillage • Planting into corn residue (no till) • Soybeans grown in striped rows between corn residue (minimum tillage)

  9. Benefits of Conservation Tillage • Environmental benefits • Reduces soil erosion by 60%-90% from rain & wind • Improvessoil and water quality by adding organic matter as crop residue decomposes • Conserves water by reducingevaporation • Conserves energy due to fewer tractor trips • Reduces air pollution from dust and diesel • Crop residue provides food and cover for wildlife

  10. Benefits of Conservation Tillage • Practical benefits • Fewer trips across the fields saves time and money (lowers fuel, labor and machinery maintenance costs) and reduces soil compaction that can reduce yields • Optimizes soil moisture, enhancing crop growth in dry periods or on droughty soils
