Question

Whal do you understand by
(1) Ammonofication (2) Nitrification.
(3) Dentrification​

Answer 1

$\huge\mathbb{\orange{NITRIFICATION}}$

In this process, the ammonia is converted into nitrate by the presence of bacteria in the soil. Nitrites are formed by the oxidation of Ammonia with the help of Nitrosomonas bacterium species. Later, the produced nitrites are converted into nitrates by Nitrobacter. This conversion is very important as ammonia gas is toxic for plants.

The reaction involved in the process of Nitrification is as follows:

2NH4+ + 3O2 → 2NO2– + 4H+ + 2H2O

2NO2– + O2 → 2NO3–

$\huge\mathbb{\red{AMONIFICATION}}$

When plants or animals die, the nitrogen present in the organic matter is released back into the soil. The decomposers, namely bacteria or fungi present in the soil, convert the organic matter back into ammonium. This process of decomposition produces ammonia, which is further used for other biological processes.

$\huge\mathbb{\orange{DENTRIFICATION}}$

Denitrification is the process in which the nitrogen compounds makes its way back into the atmosphere by converting nitrate (NO3-) into gaseous nitrogen (N). This process of the nitrogen cycle is the final stage and occurs in the absence of oxygen. Denitrification is carried out by the denitrifying bacterial species- Clostridium and Pseudomonas, which will process nitrate to gain oxygen and gives out free nitrogen gas as a byproduct.
