“…As a result, most surface layers have a darker color than sub-surface horizons. Others reported similar results in Ethiopia and China (Abate et al 2014;Ali et al 2010;Beyene 2017;Dinssa and Elias 2021;Liu et al 2016). The sub-surface horizon (<80 cm) colour of the foot slope was dark grey to brown, suggesting that soils comprised fine-textured colluvial and alluvial materials.…”

“…Moreover, the United Nations pledged to achieve sustainable development goals (SDGs) by 2030, and regional land use analyses are essential to achieving these goals. Research findings also highlighted that soil resource information is vital for sound soil use planning and sustainable fertility management (Dinssa and Elias 2021;Elias 2016;Fekadu et al 2018;Gebreselassie et al 2014).…”

Currently, soil characterization and classification are becoming the primary source of information for precision agriculture, land use planning, and management. Thus, this study was focused on perusing the landscape-scale spatial variation of soils in data-scarce areas using toposequence-based ground sampling to characterize and classify the soils. Six typical profiles representing major landforms were opened and studied for their morphological characteristics and physical and chemical properties. Results indicated that the soils were shallow to very deep in depth, moderately acidic to moderately alkaline in soil reaction, non-saline, and clay to sandy loam in texture. The soils were found to be very low to low in organic carbon, very low to medium in total nitrogen , low to medium in available P, very low in available S, very low to low in available B, high to very high in CEC and very low to very high in base saturation. The soils were found to tbe deficient in Zn but sufficient in Fe, Cu, and Mn. Following the field survey and soil analytical results, five main reference soil groups, mollic Leptosols (Eutric), Prothovertio Luvisols (Clayic, Aric, Escalic), Skeletic Fluvisols (Arenic, Densic), Haplic Leptosols (Skeletic), Haplic Vertisols (Endocalcaric, Ochric), and Haplic Cambisols (Arenic, Aric) were identified in the different parts of the topographic positions. Pedon - 2, 3, 5, and 6 were classified in I to IV land capability class (LCC) and grouped as arable land with some limitations. They were in suitable to a marginally suitable range. The severe constraints to crop cultivation in the area were low fertility, erosion hazard, and climate for all soil units. Therefore, application of manure and compost alongwith chemical fertilizer, reducing complete crop residue removal, and soil and water conservation measures are essential to overcome these common and other limitations.

“…The variation in soil color matrix noticed within and amongst the pro les might be attributed to the soil's difference in mineralogy and chemical composition, organic matter and clay contents, type of aggregates (form). The robust structure formed in the subsurface horizons is due to the overlying layers, reduction in organic matter, high clay accumulation, and reduction in plant root abundance, as was also discussed by a previous study(Dinssa and Elias, 2021). From A-horizon down to the bedrock Rhorizon the structure changes from massive to crumbly structure with depth.…”

“…S and B contents of the studied soil pro les decreased with pro le depth and were found in very low and very low to low, respectively (EthioSIS, 2014). Similarly,Dinssa and Elias (2021) reported very low to low B distribution in the Bako Tribe of western Ethiopia. The pH is retained as the main factor affecting B adsorption in agricultural soils (Santos et al, 2019), as well as soil texture, soil moisture, parent material, clay nature and content, Al and Fe (hydr)oxides, clay minerals, calcium carbonate, and organic matter and interrelationship with other elements affect the B concentration in soil(Ahmad et al, 2012;Arora and Chahal, 2010).…”

The severe constraints to crop cultivation in the area are generally low fertility, erosion hazard, and climate for all soil units. Therefore, continuous manure and compost integration with chemical fertilizer, reducing complete crop residue removal, and soil and water conservation measures are essential to overcome these common and other production limitations.
