Vineyard soils have been contaminated by long-term applications of copper salts as fungicides against mildew, raising the question of the bioavailability (and toxicity) of such accumulated Cu to cultivated plants which can replace vines. The aim of this study was to assess, in an acidic and a calcareous Cu-contaminated soil, how the extractability and bioavailability of soil Cu was affected by pH changes in the rhizosphere of two plant species (oilseed rape and tomato), in response to various… CONTINUE READING
