  Gypsum and its role in trapping ammonia gas

  Aug 01, 2014#0183;#32;In a moist environment, gypsum disassociates (separates) into its individual salt components, calcium and sulfate. When gypsum is blended into a compost windrow or mixed in a manure pile, the sulfate salt naturally attaches to the ammonia molecules, forming ammonium sulfate effectively trapping it in another stable form and preventing ammonia volatilization.
