Agriculture Application:
Ammonium sulphate is the most typical inorganic nitrogen fertilizer, mainly advantage on the agricultural is hygroscopicity is relatively small, not easy to agglomerate, excellent physical properties and chemical stability compared with ammonium nitrate; As a quick fertilizer, ammonium sulfate is a good biological fertilizer, reaction in the soil of acidic, suitable for alkaline soil and soil carbon. It is the best fast release, quick acting fertilizer can be directly used for a variety of soil and crops, can be used as kinds of seed fertilizers, base fertilizer and additional fertilizer. Particularly suitable for the soil which lack of sulfur, low chlorine tolerance crops, sulfurphilic crops, It is very popular in Japan, Southeast Asia, as well as northeast China where plant premium rice. Suitable for the rice seedling, the growth of tea, grass, vegetables, and fruit trees, effectually rapid promoting the growth of grain, vegetables, fruits, grass and other plants.
