The aim of the laboratory experiment was to determine properties of humic acids developed during decomposition of post-harvest residues of wheat, lucerne and corn in soil. Humic acids were extracted prior, and after 30 and 360 days of incubation according to the IHSS method. It was found that application of post-harvest plant residues to soil significantly modified properties of humic acids. These findings have indicated the necessity of considering crop rotation scheme in determining properties of soil humic substances.
