Magnesium Sulfate has a variety of contents and classifications, which can be divided into industrial grade and agricultural grade according to its use; According to the state, it can be divided into magnesium sulfate heptahydrate, magnesium sulfate, anhydrous magnesium sulfate, etc; Magnesium sulfate is easily soluble in water. It is unstable in the air, magnesium sulfate heptahydrate is easy to dehydrate in the air, and anhydrous magnesium sulfate is easy to absorb water.

In agriculture: sulfur and magnesium can provide rich nutrition for crops, which is conducive to crop growth and yield improvement. Magnesium, as an important part of chlorophyll, absorbs sunlight, and uses light energy to provide nutrients for crop growth, so as to promote crop growth and increase yield. It can be widely used in flushing fertilizer, water-soluble fertilizer, water-soluble fertilizer, foliar fertilizer and compound fertilizer.
