Abstract: A survey was conducted to investigate the levels of metals viz., Fe, Mn, Zn, Cu, Cd, Pb, Ni and As in soils in areas under vineyard comparing the agricultural crop lands. Five locations (vineyard - 4 and agricultural crop land - 1) were selected in each village for collecting soil sample (surface and sub-surface) with the coverage of five villages. All the vineyard soil samples recorded higher concentration of DTPA extractable Cd, Cu, Fe and Pb. The Cd concentration was found to be below critical limits in agricultural crop lands. Overall DTPA extractable Cd, Cu and Pb concentration followed the order of Kamayagoundanpalli > Surilipatti > Rayappanpatti > Anamalayanpatti > Narayanathevanpatti. The DTPA extractable Zn followed the sequence of Kamayagoundanpalli > Anamalayanpatti > Surilipatti > Rayappanpatti > Narayanathevanpatti whereas the DTPA extractable Cr, Mn and Ni concentration followed the order of Surilipatti > Kamayagoundanpalli > Rayappanpatti > Anamalayanpatti > Narayanathevanpatti.
