Uses of Copper Sulphate

Technical Grade Copper Sulphate produced by NEKK’s chemical complex can be used in agriculture as a defender (fungicide) of fruit trees, berry bushes, vegetables and city green plantations; as an additive for soil fertilizers; for preparation of Bordeaux and Burgundian mixtures.

Long-term experience of using copper sulphate in agriculture proved lack of resistance to it.

Copper sulphate can be used as treatment for grain crop storage and mordant treatment for seeds to control fungus diseases.

Also it is widely used for antiputrefactive dipping of clothes, for preservative of wood materials etc.
