AMMONIUM SULPHATE (NH4)2SO4
GOST 9097-82 (HS code 310 221 0000)
Ammonium sulphate fertilizer contains 21% of nitrogen in ammonium and not more than 24% of sulfur in sulphate-ions available for plant nutrition. It is weakly hygroscopic, less become caked, well dispersed and quickly dissolved in water, not spread in the air and hold the friability. By physical configuration of ammonium sulphate is a white or light-colored color crystalline powder, allowed light yellow and pink tone. It is also used for feeding. It can be applied not only in spring, but in autumn too, because nitrogen of ammonium sulphate is weakly washed away from soil and well assimilated by plants.
