The present study was made on physicochemical characteristics of agricultural soil samples at various stations of Tuticorin district were analyzed. Physicochemical parameters like pH, Electrical conductivity (EC), Organic carbon (OC), Organic matter (OM), available Nitrogen (N2), Phosphorus (P), Sodium (Na), Calcium (Ca), Magnesium (Mg) and Calcium carbonate (CaCO3) were analyzed under laboratory conditions. Among these, pH (6.55 to 7.25), EC (0.83 to 0.266 microhoms), OC (0.546 to 1.74%), OM (0.956 to 3.08%), N2 (0.243 to 0.516%), P (0.093 to 0.259%), Na (24.66 to 135.33 ppm), Ca (0.057 to 2.127 mg/g), Mg (0.015 to 0.068 mg/g) and CaCO3 (1.81 to 7.633%) ranges were recorded at all the stations.
