granular nitrogen fertilizer high purity ammonium sulphate
Ammonium sulfate Nitrogen > 20.5%
Sulphur > 24%
Suitable for alkalinity earth
The ammonium sulfate is made from monosodium glutamate wastewater. After extract protein concentrate by flotation, then through four efficiency units and double-effect concentrator double concentrated, get the product from concentrated liquid crystalline.

1. In agriculture, used for nitrogen fertilizer. It is a kind of action fertilizer which can make crops
thrive and improve fruit quality and yield and strengthen resistance to disaster, can be used for
common soil and plant in basic fertilizer or additive fertilizer and seed manure. It can be suitable
specially for soil lack of sulfur, but for acid soil, ammonium sulfate needs to be applied with lime.
2. Raw material of making compound fertilizer.
