The paper contains the results of the investigations of exchangeably adsorbed cation content in various subtypes of calcareous black soils from the area of Rajac, a north-east branch of the mountain Suvobor (Serbia, Serbia&Montenegro). A series of 17 representative samples of soil collected from four subtypes of calcareous black soil (organogenic, organo-mineral, brownized and loessivized black soil) has been analysed. On the basis of the obtained results, it may be clearly seen that there occurred changes of exchangeably adsorbed cation content (especially of Ca2+ and Mg2+) through various evolution stages of the investigated calcareous black soil.
