Used as a source of manganese in agricultural applications, particularly in correcting manganese deficiency in soils and crops. It is applied in liquid fertilizers, often as a foliar spray or soil drench, to support plant growth, especially in cereal grains, citrus, and vegetables where manganese plays a key role in photosynthesis, enzyme activation, root development, and leaf growth. The solution form allows for quick absorption and efficiency.

Also utilized in animal feed supplements to ensure proper nutrition in livestock, promoting bone development, metabolic functions, growth, and reproduction.

In industrial settings, it serves as a precursor in the production of other manganese compounds, such as manganese dioxide, and in electroplating processes. Commonly used in water treatment and as a component in some fungicides.
