Ammonium Sulphate Fertilizer

L Features:
Ammonium sulfate (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 as ammonium cations, and 24% sulfur as sulfate anions.

L Fertilizer uses
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 , 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.
Ammonium Sulphate will meet short term sulphur deficits of crops and pastures, crop quality requirements, or the maintenance sulphur requirements of pasture.
Ammonium Sulphate Granular is reccommended for arable and cropping situations, silo fills and drrilling seed. It is used in Cropmaster, Ammo 31 and Ammo 36 blends.
Ammonium Sulphate Standard is recommended for pastoral blends and broadcasting.

Laboratory use
In biochemistry, ammonium sulfate precipitation is a common method for purifying proteins by selective precipitation; Ammonium sulfate is extremely soluble in water and so can make very concentrated solutions, which can "salt out" proteins, causing their precipitation at particular concentrations. This provides a convenient and simple means to fractionate complex protein mixtures. As such, ammonium sulfate is also listed as an ingredient for many United States vaccines per the Center for Disease Control.
Food additive
As a food additive, ammonium sulfate is considered generally recognized as safe (GRAS) by the U. S. Food and Drug Administration, and in the European Union it is designated by the E number E517. It is used as an acidity regulator in flours and breads.
Other uses
Ammonium sulfate is used on a small scale in the preparation of other ammonium salts, especially ammonium persulfate.
A saturated solution of ammonium sulfate in heavy water (2H2O) is used as an external standard in sulfur (33S) NMR spectroscopy with shift value of 0 ppm.
Ammonium sulfate has also been used in flame retardant compositions acting much like diammonium phosphate. As a flame retardant, it lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char. Its flame retardant efficacy can be enhanced by blending it with ammonium sulfamate.
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.
Application rates and advice

Actual spreading rates will vary according to farm type, climate, productivity and soil type. Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate. Call our Customer Centre for information.

Volatilisation of ammonia from Ammonium Sulphate is very low compared to Urea, therefore the timing of the applications is flexible.
