| description | The use of exclosure for ecological restoration has become an increasingly vital approach to reversing degraded lands. Its effectiveness in restoring degraded lands could be varied with differences in climate, vegetation type and soil properties. Thus, the objective of this study was to determine the effect of exclosure on the selected physical and chemical properties of the soil. A six-year-old exclosure and adjacent open land with the same history of land-use types were selected. Soil samples were randomly collected from 0–20 and 20–40 cm depths of each land-use type and measured for texture, soil moisture content (SMC), bulk density (BD), soil organic carbon (SOC), available phosphorus (Av.P), cation exchange capacity (CEC), electrical conductivity (EC) and pH contents. The highest SMC, SOC and Av.P and the lowest BD values were measured from the exclosure. SMC, SOC and Av.P increased by 73, 51 and 55%, respectively, while BD decreased by 31% as compared to the open land. CEC, EC and pH were also influenced positively compared with the adjacent open land. The funding indicates exclosure had a positive effect on the restoration of soil nutrients, which are essential to promote vegetation growth and thereby minimize soil erosion. |
