Question

Describe Manufacturing of nitrogenous fertilizer??

Answer 1

Ammonia is produced by reacting nitrogen from the air with hydrogen from natural gas at high pressure and temperature using the Haber process (200-300 bars and around 450°C). ... Another important nitrogen-based fertilizer is the urea, which is produced by a reaction of ammonia with carbon dioxide at high pressure.

Answer 2

The ammonia is produced by the Haber-Bosch process. In this energy-intensive process, natural gas (CH4) usually supplies the hydrogen, and the nitrogen (N2) is derived from the air. This ammonia is used as a feedstock for all other nitrogen fertilizers, such as anhydrous ammonium nitrate (NH4NO3) and urea (CO(NH2)2).
