Abstract: Eight representative pedon from different physiographic unit of Beed district were characterized and classified. The cotton growing soils of Beed district are shallow to deep, black (10 YR 2.5/1) to light yellowish brown (10 YR 6/4) in colour, granular to angular blocky in structure, loam to clay in texture. The bulk density of these soils varied from 1.24 to 1.97 Mgm-3, PAWC varied from 82.25 to 301.71 mm and saturated hydraulic conductivity varied from 1.30 to 22.7 cm hr-1. The soils are slightly to moderately alkaline in nature (7.2 to 7.8), the electrical conductivity varied from 0.1 to 0.5 dSm-1. Low to high in organic carbon (0.4 to 0.9) whereas low to very high in calcium carbonate content (4.56 to 23.19 %) and high in cation exchange capacity (36.07 to 80.57 cmol (P+) kg-1). The calcium was the dominant cation fallowed by magnesium, sodium and potassium. The base saturation percent was 78.82 to 97.79 percent. The fertility status of cotton growing soils of Beed district was low to high. Taxonomically these soils were classified as Typic Ustorthents, Typic Haplustepts and Typic Haplusterts and Calcic Haplusterts. The soil-site suitability indicated that the Typic Ustorthents soils were marginally suitable were as Typic Haplustepts were moderately suitable and Typic Haplusterts soils were highly suitable for cotton crop.
