High Quality Ammonium Sulfate Fertilizer White Nitrogen 21 Granular Ammonium Sulphate
Ammonium sulfate [(NH4)2SO4] 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 21%. Pure ammonium sulfate is a white crystal, with yellowish or gray by-products, low hygroscopicity and not easy to agglomerate, so it is easier to store and more soluble in water. Ammonium sulfate is a physiological acid quick-acting nitrogen fertilizer, which is generally suitable for crops such as wheat, corn, rice, cotton, sweet potato, hemp, fruit trees, and vegetables. For soils, ammonium sulfate works best in neutral and alkaline soils, but not in acidic soils.

Ammonium sulfate is mainly used as a nitrogen fertilizer in agriculture. The advantages are that it has relatively small hygroscopicity, is not easy to agglomerate, and has excellent physical properties and chemical stability compared with ammonium nitrate and ammonium bicarbonate. Ammonium sulfate is a quick-acting fertilizer with good biological properties. Fertilizer, the reaction in the soil is acidic, suitable for alkaline soil and carbonaceous soil. The disadvantage is that the nitrogen content is low, but in addition to nitrogen, ammonium sulfate also contains sulfur, which is extremely beneficial to crops.
In addition, it is also widely used in industry. For example, it is used as a fermentation nitrogen source for enzymes in medicine, as a dyeing and printing auxiliary in textiles, and refined ammonium sulfate is used in beer brewing.
