Product performance

Magnesium sulfate heptahydrate, also known as sulfur bitter, bitter salt, epsomite, or Epsom salt, is a magnesium-containing compound.In the air (drying), it is easy to be weathered into powder, and when heated, the crystal water is gradually removed to become anhydrous magnesium sulfate.

Quality index GB/T26568-2011

The scope of application

In agriculture and horticulture, magnesium sulfate is used in soils that are deficient in magnesium (magnesium is one of the nutrient elements necessary for crop growth and the core element of chlorophyll, which plays a very important role in the photosynthesis of plants, Equivalent to the "artificial sun" in vegetable greenhouses) is usually used for potted plants or magnesium-deficient crops, such as tomatoes, potatoes, roses, etc. The advantage over other fertilizers is higher solubility.

Packaging and storage

25kg or 50kg bags, the inner layer of plastic film, the outer layer of woven bags or determined according to user needs, the product is stored in a dry, ventilated and cool place indoors.
