Intensive soil mobilization in the conventional tillage system has caused soil structure degradation, soil compaction below the arable layer, and decreased macroporosity. These changes resulted in reduced soil water infiltration rate and increased runoff, soil erosion and sedimentation in rivers and reservoirs. In the no tillage system the water erosion from the soil surface is practically controlled, and the terraces were eliminated by the farmers. Nevertheless, the surface flow is higher than it was in the conventional tillage system. With […]
