　　It is used for industrial sewage treatment in environmental protection.

　　In agriculture, magnesium sulphate is an excellent dual-nutrient fertilizer (containing Mg and S). Sulfur and magnesium are both medium elements of crops. They are the fifth and sixth major nutrient elements of crops. They can not only increase crop yields, but also It can also improve the taste of the fruit. Magnesium is a component of chlorophyll and pigment. It is a metal element in the chlorophyll molecule. Magnesium can promote photosynthesis and promote the formation of carbohydrates, protein and fat.
