“…Terefore, following the feld survey and soil analytical results, fve main reference soil groups of the World Soil Resource Base-Leptosols, Luvisols, Fluvisols, Vertisols, and Cambisols-were identifed and mapped (Table 8). Tese soil sources showed that parent material, climate, geography, biotic, and land use/land cover changes determine regional and local soil kinds and characteristics [64]. Previous study by Gebremeskel et al [65] also reported that prominent soils in the area are Cambisols, Fluvisols, Leptosols, Vertisols, and Regosols.…”

The characterization of soil landscapes is becoming increasingly important for making decisions regarding site-specific agriculture systems and soil management. This study was initiated for the purpose of identifying landscape-scale spatial soil variation using a toposequence model so that site-specific fertilization could be achieved. According to the finding, the soils were shallow to very deep in depth, moderately acidic to moderately alkaline in soil reaction, nonsaline in salinity, and clay to sandy loam in texture. The soils were found very low to low levels in most soil nutrients, very low to very high levels of base saturation, and deficient in zinc but have adequate levels of iron, copper, and manganese. The soil exchange complex was mainly dominated by Ca and Mg where the order of occurrence was Ca > mg > K > Na. The CEC values were in high to very high range. Following the field survey and soil analytical results, five main reference soil groups of the World Soil Resource Base—Leptosols (56%), Luvisols (8.5%), Fluvisols (14.4%), Vertisols (13%), and Cambisol (8.2%)—were identified and mapped. Leptosols cover the largest landmass of the watershed and mostly found at the summit and hill back slopes. On the other hand, Luvisols, Fluvisols, Vertisols, and Cambisols were found on the middle and foot slopes. According to the findings, the variation in soil source indicating that topography is the primary pedogenic element in the formation of the soil in the watershed that was under research. Therefore, having local-scale-specific soil information can assist the site-specific application of soil nutrients and amendments based on spatial variability which is tailored to the soil requirements.

This study examined the influence of land use types and soil depth on soil’s physicochemical properties in the Sugar Estate of Arjo‐Dhidhessa, western Ethiopia. This study aimed to provide baseline data for future investigations in the study area by exploring significant soil quality indicators across various land use types and soil depths. Fifteen composite soil samples were collected from selected land use types, including fallow land, cropland, irrigated land, forest land, and shrubland, at three different soil depths (0–30, 30–60, and 60–90 cm). Particle size distribution; bulk density (ρb); total porosity (Tp); pH; organic soil matter; and available texture and phosphorus. The exchangeable acidity (EA), cation exchange capacity, and exchangeable bases (EBs) were found to be influenced by land use changes and soil depth. The results revealed that the bulk density (1.43 g/cm2) is highest in the cropland subsurface, whereas forest lands tend to have a relatively high clay content (67%), moisture content (25.74%), and Tp (54.28%). While the pH of irrigated land was 5.17, that of fallow land, cropland, and forest land varied from 5.47 to 5.84. Compared with the other land uses, the forest and shrubland areas presented higher levels of soil organic matter (SOM) (2.49%) and total nitrogen (TN) (0.126%). Forest land presented relatively high SOM (2.45%), TN (0.126%), available phosphorus (AvP) (1.36%), and exchangeable calcium (Ca2+) levels (16.82 cmol/kg), whereas irrigated land had presented the lowest amounts (5.22 mg/kg), Ca2+ (3.97 cmol/kg), and exchangeable magnesium (Mg2+) (0.99 cmol/kg). In contrast, agricultural activities were found to significantly reduce soil quality, as evidenced by higher bulk densities in cropland and irrigated land as well as lower levels of nutrients, including AvP and EBs, primarily due to erosion and crop harvesting. To maintain and improve soil pH and AvP levels, it is essential to adopt sustainable land management practices that contribute to maintaining higher phosphorus levels and improving overall soil fertility.
