Abstract

Five typical soil profiles under Lower Bhavani Project Command area, representing various physiographic situations were the materials for this study. Soil texture, pH, Electrical conductivity and organic carbon content etc. were influenced by physiographic units. The infiltration rate and hydraulic conductivity were high in Lithic Haplustalf and low in Typic Haplustalf and Typic Chromustert (Black clay loam soil). The study of moisture retension at variation tension indicated that upper terraced to middle terraced soils (Lithic Haplustalf, Typic Ustochrept, Typic stifluvent, Typic Haplustalf) are having low available water content compared to lower physiography Typic Chromustert.

Keywords: Infiltration rate, Hydraulic Conductivity, Moisture retention, LBP area.
