Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.

In succinate/ammonium sulfate medium, H(2) was not detected for the first 6h because high ammonium concentration considerably reduced the nitrogenase activity to below 5 nmol/gdcw/h. After 24h, 99% of the ammonium was consumed, and the nitrogenase activity increased to 296 nmol/gdcw/h, accelerating H(2) production.

An experimental study is made of the regular pattern of the effect of such important parameters as the initial ammonia concentration, reaction temperature, liquid solid ratio and ratio of gypsum in excess in the manufacture of potassium sulfate by direct conversion of gypsum and potassium chloride in concentrated ammonia medium, and through linear regressive treatment of the experimental ...
G. Speight, in Environmental Inorganic Chemistry for Engineers, 2017. Ammonium Sulfate. Ammonium sulfate ((NH 4) 2 SO 4) is an inorganic salt with a number of commercial most common use is as a soil fertilizer since the chemical contains 21% .
Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of highmelting (decomposes above 280℃) white solid which is very soluble in water ( g/100 g water at 0℃; g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.
The reactivity of flue gas desulphurization gypsum with ammonium carbonate has been studied in the temperature range (20–50) °C. Mechanism of this reaction was suggested and the kinetics parameters characterizing the reaction were determined. A mathematical model suitable for the prediction of the conversion of gypsum was proposed.
