Magnesium Sulfate Heptahydrate

Colorless fine acicular or oblique columnar crystals. Odorless, bitter taste. Soluble in water, slightly soluble in ethanol and glycerin.

Magnesium sulfate fertilizer can be used alone or as a component of compound fertilizer. Sulphur-magnesium fertilizer can be directly used as base fertilizer, topdressing fertilizer and foliar fertilizer; it can be applied not only in traditional agriculture but also in high value-added precision agriculture, flowers and soilless cultivation. Magnesium sulfate fertilizer has the characteristics of easy absorption and does not damage the pH value of the soil.

Magnesium sulfate heptahydrate, commonly known as Epsom salt, is a hydrated inorganic salt widely used in agriculture, healthcare, and industrial applications.
