The advantages of (NH4)2SO4
(1) Can be used as nitrogen fertilizer and sulfur fertilizer;
(2) (NH4)2SO4 is Suitable for the production of low concentration of compound fertilizer. Comparing to other varieties of nitrogen fertilizer such as Urea, with advantages of good granulation performance advantages and without chloride ions.
(3)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. In addition, with excellent solubility, ammonium sulfate can form a high salt environment to make a preparing for the protein precipitation and subsequent high salt purification.
