Ammonium sulfate granular N20.5%

1) Content: Ammonium sulfate, abbreviated as ammonium sulphate, is an early applied variety of solid nitrogen

fertilizer, commonly referred to as standard nitrogen fertilizer; Containing 20% to 21% nitrogen.

(2) Property: ① The pure product is white crystal, with a slight yellow color when there are a small amount

of impurities. ② Good physical properties, no moisture absorption or agglomeration. However, if too much

sulfuric acid is added to the manufacturing process or the environmental humidity is high, it will absorb moisture

and clump Easily soluble in water, fertilizer aqueous solution exhibits acidic reactions Stable chemical properties,

non volatile and non decomposing at room temperature and pressure. ⑤ Under alkaline conditions, ammonia

volatilization occurs and nitrogen is lost. Therefore, ammonium sulfate cannot be mixed with alkaline substances

for storage and application.

⑥ It belongs to physiological acidic fertilizers, and long-term application can enhance soil acidity. The application

of ammonium sulfate in acidic soil can enhance the acidity of the soil, so lime should be added, but it should be

noted that lime and it should be applied separately; Calcareous soil contains a large amount of

Ca-CO3, and the application has little effect on soil acidity, but it can cause ammonia

volatilization loss, so it should be applied deeply.

Ammonium sulfate has excellent solubility and can form a high salt environment, preparing for protein precipitation

and subsequent high salt purification. There is a significant difference in the solubility  between zero and 25 degrees

Celsius at room temperature.

Storage precautions: Store in a cool and ventilated warehouse. Keep away from sparks and heat sources. It should be

stored separately from acids and alkalis, and mixed storage should be avoided. The storage area should be equipped

with suitable materials to contain leaks. It is a better N fertilier and with cheaper price than urea.
