“…Organic matter reduces oxidation and precipitation loss, and its chelating agents, depending on their solubility potential, increase micronutrient availability. Prior studies also indicated the highest micronutrient concentration in the top soil, decreasing down the profle [134][135][136][137][138][139]. Tese scientists found that surface soil organic matter closely correlates with accessible micronutrients.…”

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.

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 revealed that the soils were shallow to very deep in depth, moderately acidic to moderately alkaline in soil reaction, non-saline in salinity, 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 TN, low to medium in av. P, very low in av. S, very low to low in av. B, high to very high in CEC and very low to very high in base saturation. The soils were also found deficient in Zn and 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. Profile − 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 also in a suitable to a marginally suitable range. 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.
