Their insertion in agricultural practice reduces soil degradation phenomena, avoids the implementation of an intensive management and reduces production costs. It is normally designed to reduce soil strength, cover plant materials and rearrange aggregates. 2. It increases available soil water, reduces heat and drought stress, and builds up soil health in the longer term. Sowing operations are difficult with ordinary equipment. One type of minimum tillage consists in seeding small grain in sod that has been relatively undisturbed. No-tillage, direct sowing, direct drilling and conservation tillage all aim to achieve conservation agriculture.
