Ammonium sulfate
Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas The heat of reaction evaporates all water present in the system, forming a powdery salt Approximately 6000M tons were produced in 1981 Ammonium sulfate also is manufactured from gypsum (CaSO 4 2H 2 O)...
What is FGD Gypsum
Not all FGD gypsum will be acceptable for agricultural use because of high chloride content and potential perception issues associated with heavy metals Many FGD gypsum sources will not be located in areas where the cost/benefit of using FGD gypsum for soil amendment will justify the cost of transporting and handling the material...
How Do Ammonium Sulfate and Gypsum Differ?
Ammonium Sulfate, (NH4)2SO4 Ammonium sulfate is a non-hazardous, nitrogen-rich fertilizer that also helps lower soil pH The nitrogen in ammonium sulfate tends to be stable, so it is available throughout the growing season This reduces the need for repeated applications...
