use A good nitrogen (commonly known as ammonium sulphate), suitable for general soil and crop, can make the branches and leaves growth, improve fruit quality and yield, enhance crops on disaster resistance ability, as a basic fertilizer, fertilizer and seed manure. Ammonium chloride can be produced by redecomposition with salt, ammonium alum can be produced by interaction with aluminum sulfate, and refractories can be made with boric acid. The addition of electroplating solution can increase the conductivity. It is also the catalyst of food miso color, the nitrogen source of yeast culture in fresh yeast production, acid dye dyeing assistant, leather deashing agent. In addition, it is also used in beer brewing, chemical reagents and battery production. Another important role is to mine rare earths. Biological USES are also many, mostly for protein purification process. In addition, ammonium sulphate has excellent solubility and can form a high-salt environment for protein precipitation and subsequent high-salt purification.
