Abstract: Total and DTPA-extractable contents of Fe, Mn, Zn and Cu were
determined in eleven soil profiles representing four subgroups soil.
Total Fe, Mn, Zn and Cu varies from 2730 to 42700; 20 to 450 ; 20 to 190; and 10 to 50 ppm, respectively. The soils. of Cambic Gypsiorthids and Typic Calciorthids are characterized by relatively high content. of trace elements rather than the soils of Typic Torriorthents. and Typic Torripsamments. .
The statistical measure, i.e. weighted mean, trend and specific range of these, elements were computed and interpreted in terms of soil genesis and formation.
DTPA-extractable Fe, Mn, Zn and Cu range from 45 to 220; 3.5 to 85 ; 2 to 35 and 4 to 10 ppm, respectively. Generally, DTPA-extractable micronutrients are in adequate amounts in all the studied surface samples.
For the factors affecting total and DTPA-extractabl-microputrients in the studied soils, the correlation coefficient and direct and joint effects were ca1cuiated
