Abstract: By sequeatial extraction for three kinds of heavy metals, the influence of humus and its various components on the activity of Cu, Pb and Cd in black soil is discussed. Most of the Cu in soil are in organic state and insoluble residues, only a few in exchangeable stato and carbonate-combined state. The content of available Cd in soil is obviously exceeded that of Cu and Pb with increasing content of humic acid.
