| Abstract | ||||
| Erosion and degradation-related soil properties were investigated in this study. The investigation was carried out on three different sites. Top soil samples were collected from two areas at each site (represent erosion and deposition areas). Particle size distribution, bulk density, soil organic matter, EC, exchangeable and soluble ions were determined in soil samples of both erosion and deposition areas in order to assess the impact of soil erosion on those areas. Data obtained indicated that soil erosion has affected several soil properties. Clay content was increased significantly in the deposition areas, while silt and sand contents were significantly greater in the eroded areas. Remarkable decline were observed in soil depth caused by soil erosion which led to further soil deposition. Exchangeable Ca and Mg contents through soil profiles in the eroded areas were also decreased. In spite of the limitation of this study, the results could emphasize the role of soil erosion in soil degradation process and productivity. This is certainly evident within such fragile ecosystem that is characterized by shallow soils, disturbed vegetation and limited moisture content. | ||||
