Soil erosion is the major factor that has contributed to the reduction of soil fertility in the highlands of Ethiopia. This factor is reduced by soil and water conservation (SWC) practices. Hence, this study evaluated the effects of physical SWC practices and slope gradient on the soil physicochemical properties in the Agemi watershed of northwestern Ethiopia. Farmland treated by SWC such as stone-faced soil bund (SFSB) and soil bund (SB), untreated farmland (control), and slope gradient were identified in the study area. About 27 composite soil samples were collected from the treated farmland and untreated farmland with three slope classes, including lower (5–10%), middle (10–15%), and upper slopes (> 15%). Soil physicochemical properties were analyzed using the SAS 9.4 software following two-way ANOVA procedures. The results of the study showed that the content of sand, clay, total porosity, pH, soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP), cation exchange capacity (CEC), and exchangeable cations (Ca2+, Mg2+, K+) were affected (p < 0.05) by SWC practices and slope gradient. The SWC practices such as SFSB have a higher mean value of soil physicochemical properties than SB and untreated farmland. As a result, farmland treated by SFSB improves soil physicochemical properties by reducing soil erosion. Therefore, SFSB should be implemented on untreated farmland to improve soil fertility in the study area.

“…This might be due to the comparatively low bulk density and high organic matter content [71]. The outcome was also consistent with findings made by Gesesse et al [73], Challa et al [74], and Sirna and Hailu [75] who reported that higher porosity from the exclosure resulted from conservation techniques that decreased runoff. The highest total porosity reported for exclosure land could be attributed to a greater accumulation of fine particles, and organic matter content, favoring improving soil structural stability [76][77][78].…”

Establishing exclosures has become common rehabilitation and restoration of degraded lands in Ethiopia. This study examined the effects of exclosure on identified soil physical and chemical properties, and woody diversity at the Wamole sub-watershed. Representative soil samples were taken from the open grazing land and eight-year-old exclosure. Six transects and 18 plots, with an area of 20 m × 20 m and containing nine from each open grazing ground and nine from the exclosure, were constructed alongside to sample the vegetation. From every plot, by ‘X’ design, composite soil samples were collected for investigation of total nitrogen (TN), available phosphorus, cation exchange capacity (CEC), soil pH and soil organic carbon content (SOC), and the bulk density (BD) of the soil, 18 undisturbed soil samples were taken from 0 to 20 cm deep. 34 and 28 woody species belonging to 25 and 20 families were registered between exclosure and adjacent open grazing land respectively. Significantly (P<0.05) higher Index Shannon-Wiener (3.36) in the exclosure indicated better species diversity in the exclosure than in the open grazing land (3.13). Soil properties such as available phosphorus, pH, OC, TN, and CEC showed significant differences (p< 0.05) across different land uses. Exclosures facilitated to reclaim of degraded lands by re-establishing vegetation and improving soil nutrient status in a comparatively short period. It suggests that further research on socio-economic aspects of exclosures has to bring livelihood improvement in the locality to establish additional degraded open grazing lands in the research sub-watershed.

Soil erosion is the major factor that has contributed to the reduction of soil fertility in the highlands of Ethiopia. This factor was reduced by soil and water conservation (SWC) practices. Hence, the study evaluated the effects of SWC practices and slope gradient on soil physicochemical properties in the Agemi watershed of northwestern Ethiopia. Farmland treated by SWC such as stone-faced soil bund (SFSB) and soil bund (SB), untreated farmland and slope gradient were identified in the study area. About 27 soil samples were collected from the treated farmland and untreated farmland with three slope classes, including lower (5-10%), middle (10-15%) and upper slopes (>15%). The soil physicochemical properties were analyzed by two ways analysis of variance (ANOVA) using SAS 9.2. The results of the study showed that the content of sand, clay, total porosity, pH, soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP), exchangeable cations such as Ca2+, Mg2+, K+ and cation exchange capacity (CEC) were significantly affected (p<0.01) by SWC practices and untreated farmland with slope gradients. However, the content of silt, percent of base saturation (PBS) and exchangeable Na were statistically insignificant (p>0.05). Farmland treated with SFSB confirmed higher mean values of soil physicochemical properties than SB and untreated farmland. Moreover, the lower total porosity (TP) and higher bulk density (BD) were recorded on untreated farmland and upper slopes. This study concludes that farmland treated with SFSB improved soil physicochemical properties than farmland treated with SB followed by untreated farmland. Therefore, SFSB should be implemented on farmland to improve soil fertility in the study area.
