Sažetak
Nowadays the importance of organic farming and products of it are gaining more and more interest due to the growing awareness of healthy lifestyle. Whereas organic farming excludes or strictly limits the use of synthetic fertilizers and synthetic pesticides, and genetically modified organisms the composition of the soil plays only a minor role. Not only in industrial areas, but also in remote regions there is a not negligible impact of metals released by industry on the environment and arable land. Thus the amounts of extractable metals, especially heavy metals, from soil of an organic farming apple orchard in middle Croatia were determined in order to see the potential impact on apple trees and further on the collected fruits and their products. The investigated soil has the following mineral composition: quartz, dolomite, illite, chlorite, chlorite-smectite and kaolinite and organic matter ranging between 5 and 9%. Sequential extraction was used for the fractionation of trace metal content in the studied soils, using acetic acid, hydroxylamine hydrochloride, hydrogen peroxide, and ammonium acetate as extraction reagents. The obtained extraction solutions were analyzed by inductively coupled plasma – atomic emission spectroscopy (ICP-AES) for Ag, Al, Ba, Cd, Co, Cr, Cu, Fe, K, Mn, Na, Ni, Pb, Sr and Zn. The results of the extractable amounts were compared to the total amount of metal in soil determined by XRF to calculate the extractable amount of each element. Furthermore the mobilizability was determined through the extraction yields of the four steps.
