Micronutrients or ‘tracer elements’ are essential in small quantities for the growth of plants. Fe, Mn, Zn, Cu, B, Mo, Co and Cl2 are considered as micronutirents. These micronutrients may produce synergetic and antagonistic effects if they are present in excess or in deficiency level. In this study, an attempt has been made to assess the micronutrient status of Fe, Mn, Zn and Cu in Nagapattinam District of Tamil Nadu State by using Atomic Absorption Spectrophotometer. The results revealed that the order of mean status of available micronutrients was found to be Fe (6.40 mg. kg-1) > Mn (3.27mg.kg-1) > Cu (1.71 mg. kg-1)> Zn (0.97 mg. kg-1). On an average basis 56.41, 50.46, 54.85 and 79.96 percent soils were found to be deficient in Fe, Mn, Cu and Zn respectively.
