WATER RETENTION CHARACTERISTICS OF SOME IMPORTANT SOIL GROUPS OF KAMARAJAR DISTRICT, TAMIL NADU

Abstract

                                Water retention characteristics of soils representing soil subgroups Typic Chromusterts, Typic Ustropept, Udic Haplustalf, Typic Haplustalf, Vertic Haplustalf and Typic Ustorthent in Kamarajar district of Tamil Nadu were evaluated and the influence of clay, total porosity. exchangeable sodium percentage, CEC, organic carbon, electrical conductivity and aggregate stability were studied. The results indicated that clay content in the soil is the major contributing factor to variations in water retention characteristics, to the extent of 83 to 91 per cent.

Key words : Water retention characteristics, soil subgroups
