Four pedons of an irrigated river flood plain under Salandi irrigated command of eastern coastal region were characterized and classified. Gradual increase of clay and development of structure down the depth indicated presence of cambic horizon. Fluctuation of water table and alternate wet and dry condition in an irrigated regime have given rise to formation of Fe, Mn concretions and lime nodules in the subsurface horizons. Soils were imperfectly drained, neutral to alkaline and the pH values increased down the depth. A significant positive correlation was obtained between clays and CEC (r = 0.92**). Soils were of medium fertility. Soils of the higher elevation were classified as Aeric Haplaquepts and thoseoflower elevation as Typic Haplaquepts.
