Ammonium Sulfate
1.Ammonium Sulphate
Main active ingredients are 21% nitrogen and 24% sulfur, so it can bedescribed as NPK 21-0-0 24S. Generally, it is a by-product from chemical(cyanuric acid, capro, acrylonitrile, sodium cyanide, monosodium glutamate -MSG, methyl methacrylate - MMA, etc.) or steel plant.
2.Ammonium Sulphate Appearance
1).Steel Grade (also call Coke-ovens Grade) is fine white powder, after processing it can be white granular or flake.
2).Caprolactam Grade is colorless (achromatic) crystalline or yellowish crystals.

4.Application:
In AgricultureIt is one of the most common use and most typical inorganic nitrogen fertilizer. It is the best fast release, quick acting fertilizer, can be directly used for a variety of soil and crops, can be used as kinds of seed fertilizers, base fertilizer and additional fertilizer.
In Industrial
1) .In chemical industry, as the raw materials of hydrogen peroxide, ammonium alum and ammonium chloride; theminor ingredient of ammonium persulfate, lysine.
2). In welding industry, as a welding agent.
3). In textile industry, as a flame retardant.
4).In electroplating industry,as a plating bath additive.
5).In dyeing industry, as a dyeing auxiliaries of acid dyes.
6).In leather industry, as a deliming agent.
7) In food industry, as a dough conditioning agent (fermentation medium), a catalyst of sauce food.
8).In pharmaceutical industry, as a salting-out agent, it can purifying proteins by precipitation
9). In pesticide industry, as a adjuvant agent. Add in water soluble insecticides, herbicides, and fungicides, such as 2,4-D Amine Salt, glyphosate, and glufosinate herbicides.
5.Packing:
N.W.20/25/50KG PP woven bag with PE linner bag. Shrink-wrapped with pallet is available.
6.Storage:
Kept in dry and ventilating place, avoid moisture, water, rain and fire. Avoid shipment with acid, alkali class, edible orange mix of chemicals. Common transportation tools.
7.Attention:
1) Try to not use ammonium sulphate in paddy fields.
2) Ammonium sulphate are acidic fertilizers. It can increase the acidity of the soil, Therefore should pay attention to use in acidic soils with alkaline fertilizer, such as plant ash, phosphate rock powder or calcium magnesium phosphate and so on. Use in neutral and alkaline soil alkaline soils, in order to prevent calcium ion combined with sulfate ion to insoluble calcium sulfate (gypsum), caused by soil hardened, and should apply with organic fertilizer.
