Chemical Processes Involved In Fertilizers

Ammonia is the basic chemical that almost all nitrogenous fertilizers have. 80% of the energy used to manufacture fertilizers goes into manufacturing ammonia. Since ammonia is such an important chemical in fertilizers, we will be talking about the chemical process involved in ammonia.

Production of Ammonia

Ammonia can be manufactured/produced using the Haber Process. The Haber Process combines nitrogen from the air with hydrogen extracted from natural gas (such as methane), into ammonia.

This ammonia can then be used to manufacture nitrogenous fertilizers.


This shows an example of the process of manufacturing fertilizers:
K2SO4: Potassium Sulfate
NH4H2PO4: Ammonium Phosphate

*Milling: When all the substances are grinded
*Mixing: To mix all the grinded substance together
*Granulation: To make the mixed substance into grains

Of course, not every fertilizer is made the same way. This is just one out of the many ways companies use to manufacture fertilizers. However, almost any other process of manufacturing fertilizers will have the same concept as this method.
