Process
The first step in ammonification is the hydrolysis of organic nitrogen compounds, such as proteins and amino acids, by bacteria and archaea. This process breaks down the organic nitrogen compounds into smaller molecules, such as ammonia and urea.
The second step is the oxidation of ammonia to nitrite (NO−2) by bacteria and archaea. This process is known as nitrification.
The third step is the reduction of nitrite to ammonium by bacteria and archaea. This process is also known as denitrification.
The overall process of ammonification can be represented as follows:
Organic nitrogen compounds → Ammonia (NH3) → Nitrite (NO−2) → Ammonium (NH+4)
Importance
Ammonification is an important process in the nitrogen cycle. It converts organic nitrogen, which is unavailable to plants, into ammonium, which is available to plants. Ammonification also helps to recycle nitrogen back into the environment.
