Ammonium Sulfate With CAS 7783-20-2
Ammonium sulfate, also known as ammonium sulfate, is the earliest nitrogen fertilizer produced and used at home and abroad. It is usually regarded as a standard nitrogen fertilizer with a nitrogen content between 20% and 30%. Ammonium sulfate is a salt of strong acid and weak base, and its aqueous solution is acidic. Ammonium sulfate is a nitrogen fertilizer and an acid fertilizer in inorganic fertilizers. It is used alone for a long time, which makes the soil acidified and hardened and needs to be improved. Ammonium sulfate cannot be used to produce organic fertilizers. Moreover, acid fertilizers cannot be used together with alkaline fertilizers, and double hydrolysis can easily cause the fertilizer effect to be lost.
