Soil solutions expelled by high-speed centrifugation (13900 g) of intact soil sample cores at field moisture froth 30 forest topsoils (A horizons of mainly Dystric and Eutric Cambisols, according to the FAO-Unesco system) low in day, were subjected to, analysis of 60 elements, using ICP-MS and ICP-AES. Concentrations measured were related to soil, and soil solution, properties, assumed to be important for the solubility of elements,using stepwise regression analysis. On an average'tw,o thirds of the variability in soil solution concentration of elements were accounted for by, in particular, organic C concentrations, pH and/or nitrate concentrations of the solutions varying among elements from 19 to 90 %. Concentrations of elements strongly positively, related to, Null Nu Al, Be, Ge, Li, Ni, Pb, and Zn; strongly negatively related to acidity were Ca, Mo, and W. Most positively concentrations in soil solutions were B, Ba, Cd, Mg, Mn, and Sr; negatively were Nb, Ta, and Ti. Concentrations of soil Solutions correlated positively, often quite closely, with most of the other elements studied,, including La, all with Ag, Br, Cr, Fe, Ga, Hf, Hg, In, P,Th, U, Y, and Zr. Soluble organic compounds were apparently 'carriers' of these elements in the soil solution. The concentrations of element of, the soils usually, accounted, for just little variability of their soil solution concentrations.
