 ABSTRACT

The study was carried out in bengal gram growing soils of Brahmanakotkur watershed in Kurnool district of Andhra Pradesh viz., plains and uplands originated from limestone parent material under varying land uses were studied for their morphological characteristics, physical and physico-chemical properties and soil genesis. These soils were moderately alkaline to strongly alkaline (8.11 to 8.72) in reaction, non-saline (0.19 to 0.56 dSm-1), very deep in depth and had isohyperthermic temperature and ustic soil moisture regime. The texture, organic carbon (OC), cation exchange capacity (CEC) and base saturation were ranged from clay loam to clay, 0.06 to 0.49 per cent, 34.18 to 52.04 cmol(p+)kg-1 and 86.57 to 98.67 per cent, respectively. Pedons 1 and 2 were classified under Vertsiol due to presence of more than 30 percent clay   in all the horizons, slickensides and wedge shaped aggregates in sub-surface horizons and cracks in surface horizons and were classified as Typic Haplustert and Sodic Haplustert.

Key words: Characterization, Classification, Bengal gram, watershed, Cambic horizon, slickensides, Typic Haplustert, Solic Haplustert and Vertisol.
