Impacts of Land Use Types on Selected Soil Properties: The Case of Dire Enchini District, West Showa Zone, Oromia Regional Sate

摘要

The objective of this study was to assess and explore the effect of land use types on selected soilproperty of Dire Enchini District. Three composite of representative soil samples from depth of (0-25cm) werecollected randomly from (Cultivated, grazing and forest) lands which were adjacent to each other and subjectedto laboratory analysis. Physicochemical results was analyzed by One way ANOVA (P0.05) was employed tocompare the mean of soil parameter. The textural classes of present study area were clayey dominated. As thedepth increase bulk density increase in all selected land uses due to soil organic matter decrease andcompactness by field traffic. However, the total porosity of present study result by two depths indicated as thedepth increase the mean value of total porosity decrease. Generally the values show that the overall soilcondition in the present study area appropriate condition in forest and cultivated lands than grazing land.Because of grazing land has the least concentration of soil chemical properties except physical properties, claytextural particle which suggests an increasing degradation rate in soils of grazing land. Therefore, strategiesto conserve soil properties versus the expanding population in the area have to seek a sustainable solutionthat better addresses society awareness creation on appropriate management practice of land resource andwisely uses.
