Product: Ammonium Sulfate
Molecular formula: (NH4)2SO4
Properties: Colorless crystals or white particles
Application: Mainly used in agriculture as nitrogen fertilizer and has excellent physical properties and chemical stability compared with ammonium nitrogen. Ammonium sulfate is a quick fertilizer, alkaline in soil, suitable for alkaline soil and carbonaceous soil. The disadvantage is low nitrogen content, but ammonium sulfate in addition to nitrogen also contains sulfur, beneficial to crops. Also widely used in industry, such as in the medical fermentation of enzyme nitrogen source, leather, and pharmaceuticals,textile dyeing printing additives, refined ammonium sulfate used in beer brewing.

Not suitable for application on acid soil.
It is not suitable to apply ammonium sulfate on the same cultivated land for a long time, otherwise the soil will become sour and cause compaction. If it is necessary to apply, can be appropriate with some lime or organic fertilizer. However, it must be noted that ammonium sulfate cannot be mixed with lime to prevent the decomposition of nitrogen loss. Generally, the combined application of the two should be separated by 3~5 days.
