what is Gypsum ?

Gypsum is composed of calcium sulfate (CaSO4) and water (H2O), i.e. Calcium Sulphate Dihydrate (CaSO4.2H2O).

Gypsum is found in several crystalline forms. It is found in many parts of the world. Gypsum is a sedimentary mineral. It is found in layers that were formed under salt water millions of years ago. The water evaporated and left the mineral. Among the gypsum layers, there is also a limestone or clay stone.

Gypsum has several variety names that are widely used in the mineral trade.

  • Selenite” is the colorless and transparent variety that shows a pearl like luster and has been described as having a moon like glow. The word selenite comes from the greek for Moon and means moon rock.gypsum-Selenitegypsum-Selenite

      • Modifier of soil chemical properties
      • Improve biological soil properties

Regarding the alkalinity of the soil in most agricultural land, gypsum is one of the best and cheapest methods of soil improvement. Reducing soil acidity, reducing soil saltiness, decreasing SAR (sodium adsorption ratio), increasing the Ca / mg ratio, and preventing magnesium poisoning and preventing poisoning are one of the most important uses of gypsum.
