Zinc sulfate solution is widely used in agriculture as a fertilizer to correct zinc deficiency in soils, especially in crops like rice, corn, and citrus. It helps improve plant growth, enzyme activity, and overall yield. The solution can be applied directly to the soil or used in foliar sprays for quick absorption by leaves. In animal nutrition, it is added to feed to prevent zinc deficiency in livestock, supporting immune function, skin health, and growth performance. In industry, zinc sulfate solution serves as an electrolyte in galvanization processes and in the manufacture of rayon. It is also used in medicine as a dietary supplement and in oral rehydration therapies to treat zinc deficiency and support recovery from diarrhea, especially in children.
