Used as a source of manganese in agricultural and horticultural applications to correct manganese deficiency in soils and prevent crop yield loss. Applied in liquid fertilizers for foliar feeding or soil drenching, especially in crops like citrus, soybeans, and cereals. Also utilized in the preparation of animal feed supplements to ensure proper nutritional balance in livestock. In industrial settings, serves as a precursor in the production of dry manganese sulfate and other manganese-based compounds. Commonly used in electroplating baths to deposit manganese coatings for corrosion resistance and wear protection. Employed in some chemical synthesis processes as a catalyst or reagent due to its solubility and ionic properties.
