Ammonium Sulfate White Granular for Agriculture Fertilizer Product Description

Ammonium sulfate (American English; ammonium tetraoxosulfate (VI) is the IUPAC-recommended spelling;[citation needed] and ammonium sulphate in British English), (NH4)2SO4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.

Ammonium Sulfate White Granular for Agriculture Fertilizer Applications:
The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In 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.
It is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.
Other uses of potassium sulfate:
Used as a common method for purifying proteins by selective precipitation in biochemistry; Ammonium sulfate is also listed as an ingredient for many United States vaccines per the Center for Disease Control.
Used as a food additive, ammonium sulfate is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration. It is used as an acidity regulator in flours and breads.
Used on a small scale in the preparation of other ammonium salts, especially ammonium persulfate.
Ammonium sulfate has also been used in flame retardant compositions acting much like diammonium phosphate.
Ammonium sulfate has been used as a wood preservative, but due to its hygroscopic nature, this use has been largely discontinued because of associated problems with metal fastener corrosion, dimensional instability, and finish failures.
