Abstract
The paper presents the study results of the content of mobile Ni in serpentine rankers of Serbia. The samples were taken from seven wider locations (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor and Bubanj Potok) in the altitudinal zone between 100 and 1700 m. Extraction of mobile Ni was conducted with 1.0 N HC1, and its contents were determined by the method of atomic absorption spectrophotometry. The results of analysis show that around 70% of the tested samples contain 200 - 600 mg/kg of mobile Ni, which is far above the admissible quantities for the total Ni in the soil. Therefore, the serpentine rankers of Serbia contain phytotoxic concentrations of mobile Ni, which is one of the main reasons of poor growth of plants on these rankers.
U radu su prikazani rezultati istraživanja sadržaja mobilnog Ni u serpentintskim rankerima Srbije. Uzorci su uzeti sa sedam širih lokacija (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor i Bubanj Potok) u visinskom pojasu između 100 i 1700 m nad.visine. Ekstrakcija mobilnog Ni izvršena je sa 1.0 N HCl, a njegov sadržaj određen metodom atomske apsorpcione spektrofotometrije. Rezultati analiza pokazuju da oko 70% ispitanih uzoraka sadrži 200 - 600 mg/kg mobilnog Ni, što je mnogo vise od dozvoljenih količina koje se daju za ukupni Ni u zemljištu. Prema tome, serpentintski rankeri Srbije sadrže fitotoksične koncentracije mobilnog Ni, što je jedan od bitnih razloga lošeg uspevanja biljaka na njima.
