may result. Ammonium sulfate also provides sulfur and is the most acidifying N fertilizer. On a nitrogen basis, the cost of ammonium sulfate is double that of urea. However, if sulfur is also needed, then ammonium sulfate is an economical source to use. Specialty N sources such as calcium nitrate can be effective, but are many times the cost of urea.
Ammonium Sulfate General12 Ammonium sulfate ([NH4]2SO4) is commonly used as a fertilizer. In 1991, U. S. facilities produced about million megagrams (Mg) (3 million tons) of ammonium sulfate in about 35 plants. Production rates at these plants range from to 360 Mg (2 to 400 tons) per year. Process Description1
The ammonium sulfate produced in the reaction is recovered as white crystals after evaporation of the water present in the reaction mixture. Other methods of preparation are also used. For example, gypsum (CaSO 4 ·2H 2 O) can be treated with ammonia (NH 3 ) and carbon dioxide (CO 2 ) to generate ammonium sulfate.
