Abstract

Physical degradation of the soil could be said to mean the loss of soil’s structural quality. It is observed both on the surface where thin crust may be seen and also below th e surface in or below the ploughed horizon where compacted layers may be formed, particularly in conditions of excess moisture. The experiment assessed the influence of the weight of tractor passage on soil failure and compaction. The study of resistance to penetration is produced on three worked soils; unploughed, single ploughed and double ploughed at 0-30 and 30-60 cm depths. This study showed that the number of passage of the tractor affects resistance to penetration by 44 % compared to the initial state (passage 0) and the second pass makes accentuation of 11% relative to the first pass; which shows that the first pass performs compaction most important and most severe. Thus, after sometimes, it was noticed that there's a decrease compaction at 30-60cm depth which shows that the ground based of the ploughed soil experienced a decreasing compaction function..
