The advantage of magnesium sulphate over other magnesium soil amendments is its high solubility.
(2)It is used as magnesium fertilizer in agriculture and also used as feed additives.
(3) used as the weight additive for cotton, silk, filling for wood products, and also for the manufacture of porcelain paint and material of fireproof.
(4) In microbial industry, it is used as the components of growth media, additives of brewing to be the nutrition sources of fermentation. It is used to enhance the heat endurability as the filling agent in tanning industry.
(5) In light industry, it is used in production of the fresh yeast MSG and the stabilizer of the calcium hydrogen phosphate for the toothpaste production and the congealing agents for cement, as well as used in pulp and textile industry, and other industries.
