Step 1: Nitrogen-fixation

Atmospheric: Happens when Nitrogen (N2) is oxidized at high temperatures (by lightning, in internal combustion engines) to make nitrite (NO2). This can combine with water to form nitric acid (H2NO3), which is deposited on earth through rainfall.

Biological: Done by bacteria which can convert N2 into ammonia (NH3) if an energy source is present. Some get this energy by directly absorbing sunlight (blue-green algae) or by living in the roots of plants (legumes, alder trees), who provide them with food (Rhizobium, Azospirillium).

Step 2: Conversion to Ammonia. As amino acids and nucleic acids require N in the form of Ammonia, if nitrate (NO3) present, it must be converted to NH3. This is done through Nitrate reductase enzymes.

Step 3: Biological Use. Ammonia is incorporated into proteins, nucleic acids

Step 4: When organism dies, ammonia is relased back into the biosphere through the process of Ammonification, in which water is added to proteins to make carbon dioxide and ammonia. This process happens during digestion, and is also done by bacterial and fungal decomposers.

Step 5: If ammonia released into oxygen rich (anerobic) soil, other bacteria can convert it into nitrite or nitrate through the process of Nitrification:

NH4+ + 2O2 = NO3- + H2O + 2H.

This is a problem, as it gives the molecule which contains Nitrogen a negative charge, which repels it from soil particles, causing it to be easily leached into streams and groundwater.

Step 6: If soils remain anerobic, another group of poop will convert it back into inert, atmospheric N2 through the process of Denitrification. In this process, bacteria use nitrate as an Oxygen source for respiration: C6H12O6 + 4NO3- = 6CO2 + 6H2O + 2N2

During nitrification, ammonia (NH3) is first oxidized to nitrite (NO2-) by ammonia-oxidizing bacteria, and then nitrite is further oxidized to nitrate (NO3-) by nitrite-oxidizing bacteria. This process converts nitrogen from organic forms into inorganic forms that can be taken up by plants or further transformed in the nitrogen cycle.

The Nitrogen Cycle

1.Nitrogen gas in the atmosphere is captured by Nitrogen-fixing bacteria in the soil and in the root nodules of legumes. This Nitrogen is converted to Ammonium by the bacteria.

2. Nitrifying Bacteria convert the Ammonium into Nitrites and Nitrates.

3. Denitrifying Bacteria convert both Ammonium and Nitrates back into atmospheric Nitrogen.

Nitrification is the oxidation of ammonia (release during ammonification) into nitrate state. Nitrification is performed b two types of bacteria 1) Nitrite bacteria 2) Nitrate bacteria.

What two factors cause nitrification to occur?

Nitrification occurs primarily due to the activities of two groups of microorganisms: ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB). AOB convert ammonia (NH3) to nitrite (NO2-) while NOB further oxidize nitrite to nitrate (NO3-), completing the nitrification process.


The process where ammonia is converted to nitrite and then nitrate?

This process is known as nitrification and occurs in two steps. First, ammonia (NH3) is oxidized to nitrite (NO2-) by specific bacteria. Then, a different group of bacteria converts nitrite into nitrate (NO3-). Nitrification is an essential part of the nitrogen cycle in the environment.


What organisms can break the bonds found nitrogen gas?

various bacteria called nitrification and de-nitrification bacteria


What is the method to stop nitrification?

One method to stop nitrification is to use nitrification inhibitors, such as dicyandiamide (DCD) or nitrapyrin, which can help to slow down the conversion of ammonium to nitrate by inhibiting the activity of nitrifying bacteria. Another approach is to minimize the application of nitrogen-containing fertilizers to reduce the amount of ammonium available for nitrification. Improving soil drainage and aeration can also help reduce nitrification rates in waterlogged conditions.


What comes first in nitrification?

The first step in nitrification is the conversion of ammonia (NH3) to nitrite (NO2-) by ammonia-oxidizing bacteria (AOB).

Where does Nitrification occur in nature?

Nitrification occurs in the soil and in aquatic environments where bacteria, such as Nitrosomonas and Nitrobacter, convert ammonia (NH3) into nitrites (NO2-) and then into nitrates (NO3-). This process plays a key role in the nitrogen cycle, making nitrogen available for plant uptake.


The Conversion from ammonium to nitrate is known as?

Where can one find more information about nitrification?

Nitrification is the process of combining ammonia and oxygen, usually by plants or bacteria. The Environmental Protection Agency's Office of Water has a 2002 Issue Paper entitled "Nitrification" of how the process takes place and affects ground water.


How nitrogen moves through the environment in the nitrogen cycle?

Plants fixate nitrogen from the air from lightning or precipitation fixation. Bacteria in the soil also fixate nitrogen in the air. Animals eat the plants and defecate or urinate as they eat. These wastes are incorporated into the soil through decomposition as organic matter. Mineralization occurs, turning the organic nitrate into ammonium. Nitrification then occurs turning the ammonium into nitrites, and another nitrification step turns nitrites to nitrates. These nitrates are absorbed by the plants and the cycle continues.


What is the name of the process that plants use to get nitrogen?
