Ammonium sulfate is one of the first and most widely used nitrogen (N) fertilizers in agriculture industry. High solubility, equal balancing of nitrogen and sulfur, and controlling pH in all alkaline, salty and calcareous soils are just three of so many advantages of ammonium sulfate among other nitrogen and sulfur fertilizers which provide versatility for a number of agricultural applications.
Ammonium sulfate is used as a rinse or bath in deliming process of leather tanning. Ammonium sulfate is well suited for leather deliming process as the ions of iron and calcium are exchanged on a one to one basis. This facilitates a faster process than other deliming agents, and highly decreases the time and costs of the process.
Cellulose insulation (fire retardant)
Ammonium sulfate along with boric acid is used as an additive to cellulose insulation. By adding ammonium sulfate to the insulation, the fire retardant nature of the insulation is drastically increased. The reason is the fact that ammonium sulfate reduces any release of oxygen from the cellulose material and thereby prohibiting fire growth.
It is used as a dough strengthener and conditioner in bread products.
It is used as an adjuvant in pharmaceutical vaccines.
Water Treatment Industry
It is used with the added chlorine to form chloramines which lead to a longer lasting disinfectant.
It is used as a fixing agent in dyeing and printing processes.
Laminate hardening, persulfate production, metal purification, herbicide/fungicide production
