Basic Copper Sulphate(WSDTY) can dissociate or dissolve in the environment releasing copper ions. This process is affected by its solubility, which in turn is affected by pH, redox potential, dissolved organic carbon, and ligands present in the soil. Copper in soil may originate from natural sources, pesticides, and other anthropogenic sources such as mining, industry, architectural material, and motor vehicles.
Copper accumulates mainly at the surface of soils and it can persist because it has a tendency to bind to organic matter, minerals, and some metal oxides. It may leach from acidic or sandy soil.
The more acidic the soil, less binding occurs. Researchers observed that 30% of copper was bound at pH 3.9 and 99% of copper was bound at pH 6.6.
Researchers applied the equivalent of 18 kg/ha/yr of copper sulfate in irrigation water to experimental soil columns to measure copper buildup in the soil. Soil types were not specified. Nearly all of the applied copper remained in the top 3 cm of soil. The researchers concluded that irrigation water treated with copper sulfate as an algaecide could lead to soil levels that could damage crops.
A study that evaluated leaching of copper from sandy soil to water revealed lower mobility at pH 5-7. Any pH outside of this range was correlated with higher mobility. The researchers reported that the presence of calcium ions decreased leaching of copper, increasing its binding capacity. The presence of sodium ions had the opposite effect and caused more copper to leach.
Researchers spiked samples of sandy loam soil from a barley field with 0, 100, 200, 400, and 800 μmol/kg of copper. Copper became less bioavailable over the 220 days of the experiment. Soils that remained moist retained the most copper.
