Copper Sulphate in Agriculture
Copper Sulphate is widely recognized in modern agriculture for its dual role as a micronutrient vital for plant health and a powerful defense against numerous crop diseases. Essential for plant vitality, copper sulfate facilitates crucial enzymatic functions and promotes efficient photosynthesis, thereby boosting overall plant growth. Beyond its nutritional benefits, it serves as a formidable shield against fungal and bacterial infections prevalent in various crops like vegetables, fruits, and ornamental plants. Common issues such as blight, mildew, and root rot are effectively managed through its application.
Copper Sulphate as Water Treatment
Copper sulphate can be used as an algaecide water treatment to rid ponds and lakes, and swimming pools of excess algae. High amounts of algae can cause other issues in the water and copper sulphate is a safe way to treat the water without compromising ecosystem sustainability.
It is usually not toxic to fish except in koi, goldfish, and trout. The alkalinity of the water should be over 50 ppm when using copper. If the alkalinity is any lower than this, there is a risk of copper poisoning.
Conclusion
Copper sulphate, though effective for many various uses, is toxic to humans and easily absorbed through the skin. This is why proper handling and protective equipment are so important when using copper sulphate. You should avoid any contact with the skin by wearing protective gloves. If copper sulphate does get on your skin, it can cause itching and permanent yellow discolouration.
