Conversion of copper from different copper fungicides in potato cultivation

Copper fungicides are still frequently used in organic farming to control plant diseases. However, the use of copper fungicides can lead to increased copper contamination in agricultural soils. Soil properties such as pH, texture and organic matter content can influence the conversion and binding of copper. Four different copper fungicides are used in organic farming: copper sulphate (CuSO4); copper oxychloride (Cu(OH)3Cl); copper hydroxide (Cu(OH)2) and copper oxychloride hydroxide (CuCl2(OH)3). The aim of this work is to answer the question of how copper is transformed from different copper-containing fungicides in the soil-plant system, using potato as an example.
