“…Surface layer showed higher amount of available sulphur than the sub surface in all the series due to the presence of higher amounts of organic matter in surface layers than in subsurface layers. DTPA extractable Zn, Fe, Cu, and Mn ranged from (SWA) 0.27 to 0.57, 1.50 to 4.65, 0.75 to 1.36 and 2.36 to 3.42 ppm, indicating that soils were deficient (<0.6 ppm) in Zn and Fe (<4.5 ppm) in all the soil series, which might be due to the presence of high pH and calcareous nature of soil as observed by Kumarnaik et al (2020) 6). The available boron content at surface horizon was higher than sub surface horizon in all the soil series and it decreased with depth, which might be due to the accumulation of higher amount of organic residues in the surface horizons (Geetha and Naidu, 2013).…”

Aim: To evaluate the soils of Malli-1 micro watershed situated in the North-Eastern Dry Zone (Zone-2) of Karnataka for sustainable crop development. Methodology: Eight soil profiles covering all soil types occurred in the study area were selected and studied for their detailed morphological, physical and chemical properties using standard soil testing procedures. Results: Soils of Malli-1 microwatershed varied from clay to clay loam in texture, moderately to strongly alkaline in reaction with low salt content and low to medium in per cent organic carbon content. Calcium and magnesium were the prevailing cations followed by sodium and potassium. Soils were classified upto the series level as per revisions in Soil Taxonomy by utilizing soil characteristics. Majority of soils in study area represents the Vertisols, Inceptisols and Entisols order. Interpretation: These results indicate that soils were less fertile due to deficit in soil nutrients. Recommended doses of organic bio-fertilizer and inorganic fertilizer should be practiced for reclamation of soil status.
