Ammonium sulfate, also known as ammonium sulfate, is an excellent weakly acidic nitrogen fertilizer (commonly known as fertilizer powder), in which the nitrogen (N) content is 2 1.0%.
Ammonium sulfate is suitable for general soil and crops, which can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance the disaster resistance of crops. It can be used as base fertilizer, topdressing and seed fertilizer, but long-term use may lead to soil hardening.
Composition of fertilizer grade ammonium sulfate: ammonium sulfate for short, molecular formula (NH4)2SO4, molecular weight 132. 14, nitrogen content 2 1%. Properties: Ammonium sulfate (ammonium sulfate) is a white orthogonal crystal, soluble in water, insoluble in alcohol, acetone and chlorine. Ammonium sulfate containing impurities is light brown or dark brown, and reacts with alkaline substances to release ammonia gas. Wet ammonium sulfate is corrosive to steel and water. The decomposition temperature of ammonium sulfate is 280℃, and the released ammonia gas becomes acidic ammonium sulfate NH4HSO4. The change of temperature has little effect on the solubility of ammonium sulfate in water, and its relative hygroscopicity is small. Uses: ammonium sulfate (ammonium sulfate) is mainly used as nitrogen fertilizer in agriculture, which has the advantages of relatively small hygroscopicity and difficult caking, and has excellent physical properties and chemical stability compared with ammonium nitrate and ammonium bicarbonate; Ammonium sulfate is a quick-acting fertilizer and a good bio-fertilizer, which is acidic in soil and suitable for alkaline soil and carbonaceous soil. The disadvantage is low nitrogen content, but ammonium sulfate contains sulfur in addition to nitrogen, which is very beneficial to crops. In addition, it is also widely used in industry, such as fermentation nitrogen source for enzyme production in medicine, printing and dyeing auxiliary in textile and refined ammonium sulfate (ammonium sulfate) for beer brewing.
