Abstract

                                The study deals with the utility of satellite remote sensing for soil resource studies in Vellamadai village, Coimbatore district, Tamil Nadu, India. IRS 1D LISS III merged PAN data were digitally merged using IHS approach and visually interpreted to prepare soil map after the field and laboratory studies. Based on the morphological, physical, and chemical properties, seven mapping units belonging to four soil series were identified and classified according to Soil Taxonomy. The range of clay was from 10.90 to 55.97 per cent. Soil reaction ranges from slightly acidic to saline. The soils are low in organic carbon content. Surface horizons had CEC values ranging from 13.25 to 56.27 cmol P(+) kg. The soils were grouped under Inceptisol, Vertisol and Entisol.

Key words : Remote sensing, large scale soil map, soil characteristics.
