Forms of Zinc and Their Distribution in Some Soil Profiles of Tamil Nadu

Abstract

The distribution of total and available zinc and their relationship to different soil properties were studied in twenty three soil profiles representing seven major soil series of Namakkal Taluk of Tamil Nadu. Total zinc content varied from 12.6 to 391,3 ppm and the content generally increased with dopth in red soila whilo irregular pattern of distribution was observed in black, alluvial and laterite soils. Alluvial soils contained higher amounts of total zinc followed by laterite, black and red solls, Total zinc content was found to be associated positively with clay and silt content.The available sinc content varied from 0.16. τα 5.14 μμπm. Ne consistent pattern was obser ved in the distribution of evitable zinc in the soil profiles of all the soil series. The available zine was maximum in laterite soils followed by red, alluvial and black soils Significent positive correlation were established between available zinc and organic matter, pH and calcium carbo-nate were negatively correlated with available zinc.
