主 题：Land degradation Soil and water conservation Soil properties Middle Silluh Valley Ethiopia
摘 要：Community-based Soil and Water Conservation(SWC)practices have been adopted in the Tigray region since 1991 for restoration of the degraded *** effects of those conservation measures on physico-chemical properties of soil were limitedly ***,this study evaluated the effects of SWC on selected soil properties in the Middle Silluh Valley,Tigray region,Northern *** study considered conserved landscapes(terraced hillside,terraced farmland and exclosure area)and non-conserved landscapes(non-terraced hillside,non-terraced farmland and open grazing land)for comparison using a one-way analysis of variance(ANOVA).A total of 24 samples were collected from each landscape at a depth of 10–30 *** results indicated that mean bulk density(BD)was low on terraced hillside,non-terraced hillside and exclosure *** and clay content were significantly different at P0.05 for the six landscape *** mean organic matter was observed in the conserved landscape,as compared with the corresponding non-conserved *** s correlation between Soil Organic Matter(SOM)and clay content,SOM and Total Nitrogen(TN)showed strong positive ***,the results show that SWC had significantly positive effects on soil s physical and chemical properties in the study area.
