Abstract
A detailed cadastral level survey of land resources occurring in Sivagangai block of Tamil Nadu state, India, covering an area of about 44,600 ha, was carried out during the period 2006−2007. Based on this, 18 soil series were identified and 103 phases mapped at 1:12,500 scale. The study revealed severe sheet erosion on the uplands, heavy siltation of tanks and development of salinity/sodicity at the lowlands as major causes for the drastic decline in productivity. The study warrants systematic and timely efforts to arrest soil erosion on the uplands, proper maintenance of tanks to increase the storage capacity and recharge of the aquifers and providing drainage facilities to reclaim the lowlands and prevent the development of salinity/sodicity in the study area.
