Used as a source of manganese in agricultural applications, particularly in correcting manganese deficiency in soils and crops. It is applied in liquid fertilizers to support plant growth, especially in crops like soybeans, wheat, and potatoes where manganese plays a key role in photosynthesis, enzyme activation, and nitrogen metabolism. Also utilized in animal feed supplements to ensure adequate manganese intake for proper bone development and metabolic functions in livestock. In industrial settings, it serves as a precursor in the production of other manganese compounds and in electroplating processes. Additionally, it finds use in wastewater treatment to remove sulfur compounds and in the manufacturing of dry cell batteries.
