Abstract
This research studies the copper contents in vineyard soils under vineyards
affected by the long-term use of copper-based fungicides and evaluates the extent of
this influence on the super accumulation in the main viniculture growing regions in
North Macedonia. The soil samples were taken from individual vineyards located in
the Tikvesh region, from two depths: 0-30 and 30-60 cm. At the same time, control
samples were collected from each of the visited sites. The control samples were taken
from untreated nearby locations under natural conditions in order to determine the
background concentrations. The available copper (Cu) contents were analysed on
soil samples taken from 100 locations, 50 of which represent vineyard soils (organic
and conventional farming) and 50 control samples from nearby forests and sites. The
main finding is that the average available copper concentrations are significantly
higher in soils under vineyards, compared to the background concentration in control
samples, especially in these with organic farming where the use of coper-based
fungicides is more intensive. A comparison of the copper contents in vineyards to the
background concentrations of control samples clearly confirmed the anthropogenic
influence. A significantly very high level of copper (10.70-18.77 mg/kg) was
measured in the soil samples from organic farming. The control samples
contained a significantly lower concentration of copper, between average 1.39-
1.62 mg/kg (0-30 cm) and 0.68-0.88 mg/kg (30-60 cm). According to the
micronutrient rating as related to a soil test with the DTPA extraction reagent
(Jones, 2001) applied in this study, a significant potential ecological risk has been
noticed in the agricultural soil samples (organic and conventional production).
