| dc.description.abstract | Soil erosion problems are among the factors that have contributed to the reduction of soil fertility in Ethiopia. This initiated the Government and foreign partners to emphasize on soil and water conservation measure in severely eroded areas. However, the performances of soil and water conservation measures vary in their effectiveness in conserving soil and water resources thereby affecting soil physicochemical properties. The study was conducted in Dega Damot District, Agemi watershed, North West, Ethiopia with the objective of evaluating effects of soil and water conservation practices on selected soil physicochemical properties. A total of 27 soil samples collected from the top 20 cm soil depth were prepared and analyzed in the laboratory following standard procedures. The mean difference of soil physiochemical properties were tested by two ways analysis of variance. The Results of the study revealed that sand and Clay content, total porosity, PH, OM, TN, Av.P, Ca2+, Mg2+, K+ and CEC were significantly different (p < 0. 05 or p <0.01) on farmland treated with stone faced soil bund and soil bund compared to the unconserved plots as well as between three slope class. In contrast silt content, percent of base saturation and exchangeable sodium were not significantly (p > 0. 05) affected by conservation practice. Conserved farmland as well as lower slope class demonstrated higher mean values on those most soil chemical properties than upper slope class and untreated farmland. Whereas lowest mean value of clay content, total porosity as well as most chemical properties of soil and higher mean value of bulk density and clay content were observed on untreated farm land and upper slope class than treated one. From this study it was possible lo conclude that stone faced soil bund and soil bund improve soil physicochemical properties. Therefore Soil conservation activities should be scaled up in the study area and implemented in to untreated land and other areas of the district to improve soil fertility status Key words: Conservation practice, Cultivated land, Land degradation , Soil properties. | en_US |
