The part played by water-soluble organic substances in mobilization and migration of calcium in the process of transformation of a number of chemical meliorants (phosphogypsum, phosphorite and dolomite) in soils of podzolic type is discussed on the basis of experimental data. In the investigation the method of sorption lysimeters was used, Al2O3 and cationite KU-2 in H+-form serving as sorbents. It has been that mobilization of Ca2+ ions from meliorants is most active in eluvial horizon because here components of specific nature (fulvocompounds) markedly prevail in the structure of water-soluble organic substances
