Ammonium Nitrate is a nitrogen fertilizer ( contains 17% of ammonium N and 17% of nitrate N). It is made through neutralisation of nitric acid with gaseous ammonia followed by granulation.
Ammonium nitrate is produced in 2 grades:
– Grade A is used in industry for making explosives.
– Grade B is used in agriculture: As a nitrogen fertilizer may be applied to all kinds of soils and crops. Ammonium nitrate fertilizer is applied before sowing both as a basic fertilizer and a top dressing. AN is especially efficient for top dressing of grain crops in early spring.
AN is treated with anti-caking agent against caking.
