Uses:
Used as filler in paper, paints, nutrient in growing yeast, insecticides.
Treatment of soil particularly those used for leguminous crops and in the culture of groundnuts.
When mixed with manure, it acts to stabilize the volatile and dissolved nitrogenous compound, thus preventing their loss by
  volatilization and leaching. The major use in arid climate is neutralization of black alkali soils by the reaction with alkali carbonates
  that cause this condition.
For manufacture of Plaster of Paris.
