Land degradation is a serious environmental problem in Ethiopia. To address the problem, soil and water conservation practices were implemented through campaign. This study was conducted at Workamba watershed Debark district, North Ethiopia to assess the effect of campaign soil and water conservation (SWC) practice on selected soil properties. Composite soil samples from 1.5 meters above the soil bunds, at the center and 1.5 meters below the soil bunds between the two consecutive structures were collected. The soil samples were analyzed following standard laboratory procedures. Results showed bulk density (BD), electrical conductivity (EC), calcium (Ca2+), and sodium (Na+) were not significantly affected by slope gradient and terrace position and their interaction. But pH was significantly influenced by the interaction effect. Cation exchange capacity (CEC), exchangeable potassium (K+), and clay content were significantly changed with both slope gradient and terrace position. Whereas, total nitrogen (TN), available phosphorus (Av-P), and magnesium (Mg2+), and soil organic carbon (SOC) were significantly affected with terrace position and slope gradient, respectively. Because of the conservation barrier, most soil properties were better at the bottom terrace position and gentle slope gradient.

Abstract BackgroundLand degradation in the form of soil erosion and fertility depletion is the major environmental problem in Ethiopia. However to curb this problem, Soil and Water conservation (SWC) measures are commonly practiced in many rural parts of Ethiopia. This study was conducted to assess the effects of SWC measures on selected soil quality indicators in Ejersa Lafo District. For this study two peasant associations (kebeles) were selected from the district based on the severity of soil erosion and information on SWC practices. A total of 12 composite soil samples from soil 0 to 20cm depth from two sub watersheds with SWC and without SWC practices at Jamjam laga batu and Koriso Odo guba from three landscape positions (upper slope, middle slope, and bottom) were collected. All the soil samples were analyzed following the standard and recommended procedures in Ambo University chemistry laboratory and subjected to ANOVA using the SPSS computer program. ResultMost of the selected soil physicochemical properties were affected by watershed management intervention. Comparing the two farmlands, the highest bulky density of 1.37gcm-3 was observed from unconserved farmland. The results of the study also showed higher values of Soil electrical conductivity (EC), Total nitrogen (TN), Cation exchange capacity (CEC), Soil Organic matter (SOM), Organic Carbon, Available Phosphorus (Av. P) and Available Potassium (Av. K) in conserved land and those all significantly varied between farm plots. On the other hand, Sandy, pH, SOM, TN, Av. P and Av. K values were significantly affected (p<0.05) by slope and all increased from upper (>30%), middle (15-30%) and lower (8-15%). ConclusionThe contribution of watershed management intervention to improve soil physicochemical properties is significant in the study area as it improved some of the selected soil physicochemical properties of soil. Furthermore, efforts are required to enhance community adoption towards soil and water conservation. Additionally, further research has to be carried out on socio-economic aspects and impacts of the intervention on crop productivity for better understanding of the sustainable use of the land and to make a comprehensive conclusion.

Abstract Background: The Ethiopian highlands are affected by soil loss caused by soil erosion resulted in soil properties deterioration. To reverse this, different soil and water conservation (SWC) measures were spatially practiced; however, the effect of SWC and slope gradient on soil properties is not studied well in the area. Hence, this study was conducted to evaluate the effects of SWC and slope gradient on selected soil physicochemical properties at Dawnt watershed, North-western Ethiopia. The treatments were a combination of four different SWC measures with three slope gradients replicated at three sites. Disturbed and undisturbed soil samples were collected from 0-20cm soil depth and physicochemical properties were determined following standard laboratory procedures. Results: The lab results depict that sand, bulk density, moisture, particle density, porosity, pH, organic carbon (OC), cation exchange capacity (CEC), total nitrogen, and available phosphorus were significantly (P<0.05) affected by SWC measures and slope gradient. High OC (2.44%), CEC (45cmol (+) kg-1), and moisture (19.55%) were obtained from Stone-Faced Soil Bund stabilized with Grass (SFSBG) and high available phosphorus (7.83ppm) from Soil Bund (SB) while lower bulk density (1.13gm/cm3) from SFSBG. Additionally, higher clay (41.67%) and moisture (19.81%) and lower bulk density (1.14g/cm3) were obtained from the lower slope. Higher pH (6.75) and OC (2.89%) were recorded at lower slope under SFSBG and lower pH and OC (6.03 and 1.02%) at the upper slope with non-conserved. Soil chemical properties, except available potassium, were increased down the slope.Conclusion: The interactions of slope position and SWC measures affect soil texture; pH, organic carbon, and available phosphorus but do not affect soil bulk density, moisture content, particle density, total porosity, cation exchange capacity, total nitrogen, and available potassium. In generally, the soil properties were improved through integrating conservation practices with multipurpose grass species across the study watershed. Therefore, in the study watershed and other similar agro-ecologies, farmers should use integrated SWC measures to avert the rainfall-driven soil nutrient loss.

Land degradation in the form of soil erosion and fertility depletion is the major environmental problem in Ethiopia. However, to curb this problem, soil and water conservation (SWC) structures are commonly practiced in many rural parts of Ethiopia. This study was conducted to assess the effects of SWC structures on selected soil physicochemical properties in Ejersa Lafo district. For this study, two kebeles (peasant associations) were selected purposively from the district based on the severity of soil erosion and information on SWC practices. The research design employed in this study was systematic, randomized, complete block design. A total of 12 composite soil samples were collected from the depth of 0 to 20 cm at two subwatersheds, namely, Jamjam laga batu and Koriso Odo guba with SWC and without SWC structures at three landscape positions. All the soil samples were analyzed following the standard and recommended procedures. The effect of independent variables (SWC practices and landscape positions) on the dependent variables (soil properties) was statistically tested using the SPSS computer program 21. In this study, most of the selected soil physicochemical properties were affected by watershed management intervention (SWC) structures. Soil moisture content (SMC), clay, pH, electrical conductivity (EC), total N (TN), available (AP), available K (AK), and organic carbon (OC) were higher in the subwatershed treated with SWC structures (conserved), whereas bulk density, silt, and sand were higher in the subwatershed without SWC structures (nonconserved). Most of the selected soil chemical properties were significantly varied ( p < 0.05 ) between conserved and nonconserved farm land except EC. All the selected soil physicochemical properties did not show any significant variation ( p < 0.05 ) at landscape positions except sandy soil. The physicochemical soil properties of selected parameters were in good conditions in the conserved areas with higher N and OM and lower BD, indicating fertility of the soil compared with the nonconserved land. The implementation of SWC structures improved some of the physicochemical properties of soil, such as SMC, clay particle, pH, EC, total N, AP, AK, and OC in the study area. Furthermore, efforts are required to enhance community adoption towards soil and water conservation. Additionally, further research has to be carried out on socioeconomic aspects and impacts of the intervention on crop productivity for better understanding of the sustainable use of the land.

Present research work was carried out on soil erosion and crop productivity loss in Palghar and Thane districts. The study also describes tolerable soil loss and relationship between top-soil loss and yield loss. The estimated average annual soil loss was 40.45 t ha-1yr-1 before adoption of the soil and water conservation measures (by USLE method) and estimated average tolerable soil loss was 9.36 t ha-1 yr-1, for Palghar district. Similarly, for Thane district the estimated average annual soil loss and tolerable soil loss were found to be 35.89 t ha-1 yr-1 and 9.61 t ha-1 yr-1, respectively for Thane district. The estimated average conservation practice factor (P) factors were obtained as 0.32 for Palghar district and 0.30 for Thane district to bring the soil loss below the tolerable limit. After adoption of soil and water conservation measures, the estimated soil loss were 9.02 t ha-1 yr-1 and 9.38 t ha-1 yr-1 for Palghar and Thane districts, respectively.

This study aimed to evaluate the effects of soil and water conservation (soil bund with desho grass and soil bund only) at different landscape positions on selected soil properties and farmers’ perception in the Hobicheka sub-watershed (with an area of 400 ha) of Kechabira District. Composite soil samples were taken from soil bunds with desho grass and soil bunds only at three landscape positions with three replications, whereas 117 respondents were identified using simple random sampling. The result revealed that the clay, soil moisture content, soil pH, OC, TN, Av.P, and CEC were higher in soil bund with desho grass as compared to adjacent soil bund only, whereas, bulk density, silt, and sand contents were higher in adjacent soil bund only compared to soil bund with desho grass. About 83.5% of the respondents were users of soil and water conservation measures and among them, 40.19% perceived that soil bund with desho grass has an effect on soil properties, while 25.35% perceived that soil bund only had better soil and water conservation practices. Respondents’ years of experience, education level, and access to soil and water conservation extension services significantly ( p ≤ 0.1 ) affected their perception of the use of soil bunds with desho grass. Therefore, soil bund with desho grass at appropriate landscape positions by considering farmer perception improves the soil’s physicochemical properties.
