The contents of adsorbed Ca and Mg and their ratio (Ca/Mg) were researched in the serpentinite rankers of Serbia. The samples were taken from seven wider locations (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor and Bubanj Potok) in the altitudinal belt between 100 and 1700 m. Altogether 32 soil profiles were opened and 47 soil samples were analyzed. The percentages of adsorbed Ca and Mg were determined by the method of the Atomic Absorption Spectrophotometry, after extraction with NH4-acetate. The study results show that the content of adsorbed Mg-ions in almost all analyzed samples was higher than the percentage of adsorbed Ca-ions, so their ratio (Ca/Mg) is less than 1. This Ca/Mg ratio has an unfavorable impact on the plant development and it was concluded that this is one of the basic reasons of the low productive capacity of the serpentinite rankers in Serbia.
U radu su prikazani rezultati istraživanja sadržaja adsorbovanog Ca i Mg kao i njihovog odnosa (Ca/Mg) u serpentinitskim rankerima Srbije. Uzorci su uzeti iz sedam širih lokacija (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor i Bubanj Potok) u visinskom pojasu između 100 i 1700 m nad.visine. Ukupno su otvorena 32 pedološka profila i analizirano je 47 uzoraka zemljišta. Sadržaj apsorbovanog Ča i Mg određen je metodom atomske aprsorpcione spektrofotometrije, posle ekstrakcije sa NH4-acetatom. Rezultati istraživanja su pokazali da je skoro u svim ispitanim uzorcima sadržaj apsorbovanog Mg-jona veći od sadržaja apsorbovanog Ca-jona, te je i njihov odnos (Ca/Mg) manji od jedinice. Ovakav odnos Ca/Mg se nepovoljno odražava na uspevanje biljaka i smatramo da je jedan od osnovnih uzroka niske produktivne sposobnosti serpentinitskih rankera Srbije.
