• Gypsum and its role in trapping ammonia gas

    Aug 01, 2014· Gypsum has more sulfate available so it can trap more ammonium than superphosphate. The more product blended in the soil, the more ammonia was trapped. The key is to predict the amount of nitrogen per ton of material that will volatilize and then apply enough gypsum to capture that ammonia into a stable ammonium sulfate form.
