Molecular formula:(NH4)2SO4
Apperance: White or light yellow granular or crystal
Description：
Ammonium Sulphate Granules fertilizer is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.
Ammonium Sulphate Granules fertilizer, also known as ammonium sulfide, is the earliest nitrogen fertilizer produced and used at home and abroad. It is usually regarded as a standard nitrogen fertilizer, and the nitrogen content is between 20% and 30%. Ammonium sulfate is a strong acid and weak base salt, and its aqueous solution is acidic. Ammonium sulfate is a nitrogen fertilizer and acid fertilizer in the Chemicalbook fertilizer. Long-term single use causes soil acidification and compaction, which needs to be improved. Ammonium sulfate cannot be used to produce organic fertilizer. Moreover, acidic fertilizer can not be used with alkaline fertilizer, and double hydrolysis is easy to lose the fertilizer effect.
Ammonium Sulphate Granules fertilizer is a physiologically acidic quick-acting nitrogen fertilizer, which is generally suitable for wheat, corn, rice, cotton, sweet potato, hemp, fruit trees, vegetables and other crops. For soil, ammonium sulfate is most suitable for neutral soil and alkaline soil, but not suitable for acidic soil. It is also used as an analytical reagent (precipitator, masking agent), supporting electrolyte in electrochemical analysis, microbial medium and ammonium salt preparation.
Application methods:
1. As base fertilizer. When ammonium sulfate is used as the base fertilizer, the soil should be covered deeply to facilitate the absorption of crops.
2. For topdressing. This is the most suitable method of application.There are obvious differences in the application of ammonium sulfate to different crops, such as when it is applied to fruit trees, it can be applied in trenches, rings or holes.
3. More suitable for seed fertilizer. Because ammonium sulfate has no adverse effect on seed germination.
