Attempts were made to evaluate correlations of total trace elements with various soil characters in the hope that such correlations would allow prediction of the trace element status of paddy soils in Tropical Asia. Among the 11 trace elements studied, Ni and Cr showed by far the highest correlation, followed by the pairs of V and Zn, Ni and Zn, and Cr and Zn. High positive correlations of trace elements with soil characters were found for the following pairs : total Fe_2O_3 and V and Zn, total K_2O and Rb, total CaO and Sr, total TiO_2 and V, total Al_2O_3 and Zn, 10Å clay content and Rb, clay and V, and sand and Zr. Among the negative correlations, the highest was between total SiO_2 and V, followed by those between total SiO_2 and Zn and sand and Zn. Soil material classes and inherent potentiality ratings previously established were found to have some value for the prediction of the status of certain trace elements in soil.
