Description:
Ammonium sulfate[ NH4)2SO4] was one of the first and most widely used nitrogen(N) fertilizers for crop production. It is now less commonly used,, but especially valuable where both N and sulfur (S) are required. Its high solubility provides versatility for a number of agricultural applications.
Pure chemicals of ammonium sulfate are colorless rhombic crystals.Industrial products are white color, light grey or light yellow or yellowish-brown color crystal because of different impurities
Features:
Industrial ammonium sulphate is white or light grey crystal. It is hydroscopic,and apt to dissolve in water(not in alcohol or acetone),and it will become solid blocks when absorbing moisture. The aqueous solution is alkalinous. It reacts with alkali to release ammonia gas.
Ammonium Sulphate is suitable for general crops and soils,but there’re still some points to note.
1. Cannot be contacted/mixed with alkaline substances
2. Cannot be applied on the same farmland for a long time
3. Not suitable for use on acidic soils
