Abstract
The data on soil copper accumulation and slope migration due to long-term use of copper-containing pesticides in vineyards over 200 years old with different management systems in the conditions of the Fruska Gora region of the Autonomous Province of Vojvodina, Republic of Serbia are discussed. The study focused on brown forest residual carbonate soils found in sloping landscapes with different length, steepness and exposure. The total copper content in the soil on a permanently vegetated slope with a 10º steepness was 2-4 times higher on the farm with an archaic management system compared to the farm with a traditional management system on a 5º steep slope. The copper content variation ranged from 84.5-136.6, 72.3-189.4, and 41.0-247.5 mg/kg in horizons 0-5, 5-15, and 15-30 cm respectively. Copper migration down the slope was observed in both vineyards, although with different intensities. The coefficient of lateral differentiation for farms with lower slope steepness was between 0.90 and 1.45, while for those with higher steepness, it ranged from 0.96 to 5.57. The highest values of the coefficient were observed in the transaccumulative facies at a depth of 15-30 cm. The total copper content in the topsoil of the transit site of the ampelocenosis slope with archaic cultivation system exceeded by 21-47% the maximum permissible value in the Republic of Serbia, while in the lower part of the slope, in the horizons 5-15 and 15-30 cm, it was 2-3 times higher than the normative value.
