 3.Application

 

 

1.)In agriculture, used for nitrogen fertilizer. It is a kind of action fertilizer,which can make crops thrive and improve fruit quality and yield and strengthen resistance to disaster, can be used for common soil and plant in basic fertilizer, additional fertilizer and seed manure. It can be suitable specially for soil with lack of sulfer, but for acid soil, ammonium sulfate needs to be applied with lime.

2.) Raw material of making compound fertilizer.

3.)In chemical industry, it is used for raw material in making oxydol, ammonia-alum and ammonium chloride;

4.) In Welding Industry, used for welding agent;

5.) In textile industry, ued for fire retardant of textile fabrics;

6.) In electroplating industry, used for electrobath additive;

 

 

 4.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.

 

5.Attention

 

 

 

• Try to not use ammonium sulphate in paddy fields.
• 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.
