    Nitrogen fertilizers are made from ammonia (NH 3) produced by the Haber–Bosch process. [28] In this energy-intensive process, natural gas (CH 4) usually supplies the hydrogen, and the nitrogen (N 2) is derived from the air. This ammonia is used as a feedstock for all other nitrogen fertilizers, such as anhydrous ammonium nitrate (NH 4 NO 3 ...

The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) known as UN32 or UN-32, which consists of 45% ammonium nitrate , 35% urea and only 20% water.
