    Solution

    Excessive soil tillage is associated with soil degradation processes such as compaction, a decrease in soil stability and structure, and increased soil erosion. Soil pores are closed, imposing severe limitations on infiltration and increasing runoff. Soils with high permeability will allow more infiltration and less runoff.
