AB This study investigated changes in copper accumulation and fractionation based on the depth of soils obtainedfrom active and abandoned vineyards. Soil samples were collected at different depths in three areas with activeand abandoned vineyards, and the concentrations of total copper and copper fractions were measured in thesesoil samples. Results revealed that in active vineyards, total copper accumulation was the highest in the firstlayer of soil (depth = 0–2 cm), with concentrations (193–892 mg kg−1) considerably higher than those in thedeepest soil layer (depth = 40–50 cm; concentration = 63–71 mg kg−1). This accumulation was significantlycorrelated with the total carbon concentration in the soil. However, the total copper concentration in abandonedvineyards (84–374 mg kg−1) was the highest in the subsurface layers (depth = 10–15 cm) and was not significantlycorrelated with the total carbon content. Moreover, the percentage of available copper was lower inabandoned vineyards than in active vineyards. In terms of copper fractionation, the main fraction in activevineyard soil was copper bound to organic matter, whereas the main fraction in abandoned vineyard soil wasresidual copper. Therefore, vineyard abandonment and its transformation into forest changed the distributionand fractionation of copper based on soil depth, thus decreasing the amount of available copper and improvingthe soil quality, which could enable new ecosystems.
