In order to test the effect of soil physical and chemical properties on the content and availability of trace elements (TEs), total of 52 soil samples from 26 representative vineyards were analysed (from depths 0-30 cm and 30-60 cm), which belong to Srem, Subotica and South Banat wine sub regions. Collected samples were analysed for pH, CaCO3 content, organic matter (OM), total organic carbon (TOC), granulometric fractions, pseudo total content TET (soil degradation with HNO3 and H2O2): As, Co, Cr, Cu, Fe, Ni, Pb, Zn and available content TEEDTA: Cu, Fe, Mn, Pb (extraction in EDTA). Pollution and potential pollution of the land with copper was determined due to intensive and long-term application of copper-based fungicides. Based on determined statistically significant correlations, if was found that pH increase affects content reduction and availability of TET and TEEDTA, except in case of AsT. Content reduction of AsT, FeT, NiT and ZnT was determined, with increased OM content in soil layer 0-30 cm. OM content affects the increase of available PbEDTA. Contents of AsT, CrT, FeT, MnT, NiT, PbT, ZnT increase with the increment of clay and silt content, and simultaneously reduce with the increment of fine and coarse sand content, in both soil depths. Available FeEDTA, MnEDTA and PbEDTA, as well as their total content, are affected by the particle size. Availability of CuEDTA that is of anthropogenic origin, increases with the content of coarse sand in both soil layers, but reduces with the content of fine sand in topsoil layer.
