硫酸锰在自然界中以多种矿物形式存在，例如，阔锰矿，五水辉石，方石英和绿矾。 在各种超氧化物歧化酶中发现了锰。硫酸锰具有多种工业应用，例如染色，瓷釉以及肥料和沸腾油的制造。 MnSO4在生物学研究（例如地衣芽孢杆菌的培养和植物染色体异常的诱导）中用作锰离子的来源。 MnSO4已被用于研究人骨骼肌中内源糖蛋白的酶依赖性糖基化。
Manganese sulfate is present in nature as numerous mineral forms such as, jokokuite, pentahydrite, szmikite, and mallardite. Manganese is found in various superoxide dismutases.
Manganese (II) sulfate monohydrate has been used as a micronutrient for preparation of nutritive medium for growth of sugarcane plantlets. It has also been used as a trace element in the preparation of N6 complete nutrient liquid medium for growing mycelia of H. cylindrosporum.
硫酸锰（II）一水合物经过植物细胞培养试验（0.6μg/ ml），适用于植物细胞培养实验。硫酸锰（II）是几种植物细胞培养基的组分，包括：Chu's N6;DKW/核桃；Murashige和Skoog；和Gamborg的B-5培养基。

Manganese sulfate has various industrial applications such as dyeing, porcelain glazing, and the manufacture of fertilizers and boiling oils. MnSO4 is used as a source of manganese ion in biological research, such as in culturing of Bacillus licheniformis and the induction of chromosomal abnormalities in plants. MnSO4 has been utilized to investigate the enzyme dependent glycosylation of endogenous glycoproteins in human skeletal muscle.
