Abstract

                                The distribution of total and available copper and their relationship to different soil properties were studied in twenty three soil profiles representing seven major soil series of Namakkal Taluk in Tamil Nadu. The total copper content varied from 12.6 to 105.5 ppm and increased with depth. Laterite soils contained more of total copper than black, alluvial and red soils and the total copper was closely related to available copper, clay, silt, calcium carbonate, fine and coarse sand. The available copper content varied from 0.20 to 1.13 ppm and the content showed an irregular distribution with reference to depth. Alluvial soils contained more of available copper than others.
