Where is better Manganese sulfate

Where is better Manganese sulfate? For many people this is a strange object, and here's the introduction to it:

Manganese sulfuric acid is a kind of microelement that is needed for the production of fatty acid. Therefore, manganese sulfate can be applied as fertilizer to soil and can increase production. Manganese sulphate added to animal feed, has the effect of fattening. Manganese sulfate is also the raw material and analytical reagent for other manganese salts. Manganese sulfate is also used in industrial production of electrolytic manganese, dye, paper and ceramics.

Because of the deliquescence, the scope of application is limited. Manganese sulfate does not ignite, it is stimulating. Inhalation, ingestion or percutaneous absorption is harmful and stimulating. Prolonged inhalation of the dust can lead to chronic manganese poisoning, with early onset of neurasthenia syndrome and neurological dysfunction, and later tremor paralysis syndrome. Harmful to the environment, the water can cause pollution.
