Abstract

                                Two field experiments were conducted in the Typic Haplustalls and Typic Ustor thents soils of Tamil Nadu to determine the effect of continuous cropping and ferti- lization on the changes in micronutrient availability. There was a greater rate of depletion of micronutrients in Typic Haplustalfs than the Typic Ustarthents soils. Rate of depletion of micronutrient was highest for zinc followed by copper, manga- nese and iron in both these soils indicating the need for proper micronutrient fertilization in Typic Haplustaffs.
