“…However, focusing only on agricultural lands, soil pH might change slightly for different slope classes ( Table 2). The highest pH value was obtained on agricultural land, similar to the results reported by Bewket and Stroosnijder (2003).…”

Addis H., Klik A., Oweis T., Strohmeier S. (2016): Linking selected soil properties to land use and hillslope -A watershed case study in the Ethiopian Highlands. Soil & Water Res., 11: 163−171.Deforestation of native forests for crop production in the Gumara-Maksegnit watershed, located in the Lake Tana basin, Ethiopia, dramatically increases the vulnerability of the soil for rainfall driven erosion. Hence, the central task of the study is to investigate general links of land-use and topography related to selected soil properties. The 53.7 km 2 watershed was divided into a 500 × 500 m square grid to sample bulk density (ρd), pH, soil organic carbon (SOC), total nitrogen (TN), available phosphorus (AP), and texture of topsoil. Such properties were investigated with respect to the two main land-uses, forest and agriculture, and three different slope steepness classes, 0-10%, 10-30%, > 30%. Descriptive statistics and correlation analyses were undertaken to explore potential dependencies of the obtained soil parameters according to land-use and slope steepness. The study indicates higher SOC, TN, silt and sand content in forest soils compared to agricultural soils, while solely ρd is lower in the forest soil. Overall increases of SOC, TN, silt, and sand content from the gentle to the steep slopes have been observed for both land-uses. In contrast, clay content and ρd seem to increase from steep to gentle slopes on agricultural areas, which might be due to accumulation of particularly fine soil particles eroded from the steep areas. Basic correlations valid for all land-uses and slope steepness classes have not been detected. Nevertheless, the study suggests slope steepness as a tool to assess the potential drivers of soil depletion in the Ethiopian Highlands.

“…The amount, rate and intensity of land use changes are mainly considerable in developing countries (Rao and Pant, 2001).The outcomes of these changes are deterioration of soil physicochemical properties, increased soil erosion or soil compaction (Rao and Pant, 2001) and land degradation (Woldeamlak Bewket and Stroosnijder, 2003;Khresat et al, 2008). As a result, cultivated soils in different parts of the tropics are now below their potential levels.…”

Assessing the impacts of different land uses on soil physicochemical properties is a fundamental step towards sustainable land management. This study was conducted in Agedit watershed, northwest Ethiopia with the objective of determining the effects of land use and soil depth on soil physicochemical properties. Three major land use types: natural forest, grazing and cultivated lands were selected while soil samples were collected in the 0-20 and 20-40cm depths. Standard soil analytical procedures were followed in carrying out soil analysis. Statistical analysis revealed notable variations due to differences in land use type and soil depth. Sand and clay particles, bulk density, total porosity, pH, organic matter, total nitrogen, available phosphorus, cation exchange capacity and exchangeable K and Na were significantly affected (p ≤ 0.05 and/or p ≤ 0.01) by land use. In contrast, silt, particle density, carbon to nitrogen ratios, exchangeable Ca, and Mg and PBS were not significantly (p > 0.05) affected. With soil depth, higher mean values of total nitrogen, organic matter, exchangeable K and pH were recorded in the 0-20 cm than in the 20-40 cm depth. A shift from forest to other land use types caused a significant decline on soil fertility parameters which contributed to low agricultural productivity. The study area, therefore, needs immediate intervention to protect the remnant forests and to replenish the degraded soil properties for sustainable agricultural productivity.

“…The higher range of the available phosphorus (P) in all the soils of this zone could be ascribed to inorganic sources of P from mineral weathering which have considerable importance in their contribution to soil available P as intensified human practices increase the rate of weathering and encourage decomposition (Bewket and Steroosnijder, 2003). According to Sharma and Kanwar (2012), the availability of phosphorus in soil is highly pH dependent with maximum availability near neutral soil pH, which corroborated the higher content of available phosphorus in the soils of dry temperate zone of Himachal Pradesh.…”
