In agriculture, epsomite salt is used as magnesium fertilizer. Magnesium sulfate is the main variety of magnesium fertilizer. It contains both magnesium and sulfur nutrients, which can significantly improve the yield and quality of crops. At the same time, it can also promote the absorption of silicon and phosphorus in crops.

As base fertilizer or topdressing fertilizer, generally, 13–15 kg of magnesium sulfate are applied per mu. 1-2% epsomite salt solution was the best for topdressing (foliar spraying) at the early stage of crop growth.

For the microorganism industry, magnesium sulphate heptahydrate can be used as the composition of culture medium, the additive for brewing, and the magnesium for brewing water, which is used as the nutrient source of fermentation.
