50KG bag N 21 Ammonium Sulphate exporter High quality Nitrogen fertilizer CAS 7783-20-2
Ammonium sulfate, commonly known as standard nitrogen fertilizer; Nitrogen 20% ~ 21%.
Properties: 1. Pure product is white crystal, with a small amount of impurities is a little yellow.
2. Good physical properties, no moisture absorption, no caking. However, if the manufacturing process to add too much sulfuric
acid or environmental humidity, will be hygroscopicity agglomerate.
3. Easily soluble in water, fertilizer aqueous solution is acidic reaction.
4. Stable chemical properties, no volatilization and decomposition under normal temperature and pressure.
5. Under alkaline conditions, volatilization of ammonia and loss of nitrogen occur. Therefore, ammonium sulfate should not be
mixed with alkaline materials for storage and application.
