Thirty one representative surface soil samples collected from 11 villages of Yerpedu mandal were analyzed for physico-chemical properties. Soils were slightly to strongly alkaline in reaction and non saline to strongly saline. Texturally soils were classified as loamy sand, sandy loam, sandy clay loam, sandy clay, clay loam and clay. The soils were low in organic carbon (0.28%), calcareous (7.53% CaCO3) and cation exchange capacity varied from 36.28 to 69.22 c mol (p+) kg-1 soil. The soil organic carbon per cent was low (0.28%), soils were calcareous (7.53% CaCO3), cation exchange capacity (CEC) ranged from 36.28 to 69.22 c mol (p+) kg-1 and ESP varied from 7.03 to 37.83 with a mean value of 19.75.
