Conclusion	Pass

 

Fertilizer	As an excellent nitrogen fertilizer ,it can make foliage growth vigorous, improve fruit quality and yield, and enhance crop resistance to disasters, can be used as basal fertilizer, fertilizer and fertilizer.
spray adjuvant	It is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.
protein purification process	Ammonium sulfate is an inert substance and not easy to react with other bioactive substances. It can protect the protein activity in the purification process.
Food additive	It is used as an acidity regulator in flours and breads.
Mining the rare earth	Ammonium sulfate is the raw materials of mining the rare earth,using ion exchange membranein to get the mine element, and then collect miscellaneous,   precipitating, crushing, burning ,then it will be rare earth ore
Battery production	It can increase the conductivity when adding into the plating solution
