Brand:aa

Product detail:

             ammonium sulphate fertilizer

 

 

 

·Provides an equal balance of nitrogen and sulphur

·Meet short term sulphur deficits of crops and pastures

·The safest nitrogen fertiliser to mix with non Superphosphate based fertilisers

 

 

Property:

 

It is colorless crystal or white crystalline powder,no smell.It is easily soluble in water,but insoluble in alcohol and acetone. Easy absorption of moisture agglomerate, with strong corrosive and permeability. Has hygroscopic, moisture absorption into pieces after consolidation.It can completely broken down into ammonia and sulphuric acid when heated to 513 °C above. And it release ammonia when it react with alkali. Low poison, stimulating.
