Applications:

1.Used as a fertilizer in agriculture, magnesium is one of the major components of chlorophyll.
2.Often used in potted plants or magnesium deficiency of crops, such as tomatoes, potatoes, rose and so on, the advantage is higher solubility than others.
3.Animal husbandry: magnesium fertilizer, used for pasture can also adding suitable amount of magnesium sulfate in the feed and drinking water, can satisfy the need of cow leather fat growth, and greatly improve the quality and quantity of cow milk.
4.Industrial used for ABS and PVC resin synthetic addition agent, paper making, printing and dyeing, monosodium glutamate, yeast fermentation and mineral water additive, etc.
5.Medicine: have effect such as catharsis, diminishing inflammation, detumescence, detoxification, pain suppression, inhibit central nervous, anticonvulsion, etc.
