Copper sulphate, a common copper salt, has been available from us in high purity. This chemical compound has a chemical formula of CuSO4 and exists as a series, thus differing in hydration. Gardeners and commercial farmers commonly use it to prevent problems with fungus. The copper statue of the soil, together with the frequency of application and quantity of copper sulfate applied, will determine the effects of copper sulfate on plants.
When soil is copper-deficient, young plants may develop chlorosis, which leaves yellow due to lack of chlorophyll. Copper-deficient soil is likely to cause wilting, a lack of blossoms, and a reduction in fruit harvest. Copper sulfate prevents these problems.
