Abstract
Animal enclosures such as poultry houses generate high amounts of ammonia that adversely affect weight gain and mortality or the animals, particularly among young chicks. The addition of a deliquescent salt, such as calcium chloride, to alum to treat animal waste products rapidly activates the alum to remove ammonia from the atmosphere. The ammonia sulfate by-product is useful as a nitrogen fertilizer.
