Detailed pedological and agrochemical analyses were conducted for the purpose of soil characterisation in the wine region of Šumadija, in order to obtain the designation of origin of wine (geographical indication). In total, 158 soil samples were collected from two depths (0-30 and 30-60 cm) at 10 localities, throughout the area of 44 ha. At each locality, one sample was taken from two depths and used as control. All of the tested vineyard plots were georeferenced, and the data represent real-world surfaces. The collected samples were tested for total content (destruction with HNO3/ H2O2), and accessible content (EDTA) of Cu, Mn, Zn, As, Cd, Cr, Ni, and Pb. Content of Hg was obtained by the direct solid sample method. MAC levels prescribed for Zn, As, Cd, Pb, and Hg were not exceeded in any of the tested samples. Accessible content of Zn was relatively low, ranging between 0.5-5.8 mg/kg. Copper content was increased in one quarter of the area of exploited vineyards, exceeding the critical concentration of 60 mg/kg. The area with Cu concentrations exceeding the prescribed MAC levels was very small, and none of the surfaces exhibited phytotoxic levels of copper (50 mg/kg for accessible content). The prescribed MAC level for nickel and chromium which have geochemical origin was exceeded in a significant number of samples. Content of nickel exceeded the prescribed MAC level on nearly 30% of the tested locations. Accessible content of nickel was low. Content of chromium exceeded the prescribed MAC level in 10% of the tested locations. Maximum value obtained in the research was 108.7 mg/kg, close to the prescribed MAC level. Accessible chromium content was below the level of detection (0.5 mg/kg) in all of the analysed samples. The tested soils exhibit high quality, and suitability for the production of health-certified grapes and wine.
