Manganese sulfate monohydrate is a hydrate that is the monohydrate form of manganese sulfate. It has a role as a nutraceutical. It is a hydrate, a manganese molecular entity and a metal sulfate. Manganese sulfate usually refers to the inorganic compound with the formula MnSO4·H2O. This pale pink deliquescent solid is a commercially significant manganese salt. Approximately 260,000 tonnes of manganese sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds. Manganese-deficient soil is remediated with this salt. 
Manganese(II) sulfate usually refers to the inorganic compound with the formula MnSO4·H2O. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260,000 tonnes of manganese(II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds. Manganese-deficient soil is remediated with this salt.

Manganese sulfate (MnSO4) is a chemical compound that has several industrial, agricultural, and medical applications due to its unique properties and the essential role of manganese in various biological processes. Here are some of its key applications:
