minimum tillage

Minimum tillage is an agricultural technique that involves disturbing the soil as little as possible. This contrasts with conventional tillage, which uses plowing and cultivating to prepare the soil for planting and manage weeds. Minimum tillage methods aim to preserve soil structure, reduce erosion, and improve water retention.12

Techniques include seeding directly into undisturbed sod or planting in narrow slits or holes where seeds are placed. Crop residues from previous harvests are left on the surface to protect the soil and act as mulch, which helps retain moisture and suppress weeds. While conventional no-till often relies on herbicides to manage weeds, organic no-till practices may use crop rotation and cover crops. Benefits include reduced equipment, fuel, and fertilizer needs, as well as potential for carbon sequestration.12
