Question
It is advised to add gypsum to manure in the cattle
shed. Reason behind it is?Solution
Gypsum (calcium sulfate) is added to manure primarily as a preventative measure against nitrogen loss. It reacts with ammonium carbonate, an intermediate formed during urine decomposition, to create ammonium sulfate, which holds nitrogen in a stable form, preventing it from volatilizing as ammonia and being lost to the atmosphere.Â
