3).Packing:

 

25kg or 50kg pp bags ,pallet available,depend on custmer requirement

 

4).Application:

 

Mainly used as fertilizer, applicable to all kinds of soil and crop. Can also be used in textile, leather, medicine, etc.

 

5).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.

 

6).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.
