In the nitrogen cycle, nitrogen-fixing bacteria play a crucial role in converting gaseous nitrogen (N₂) into ammonia (NH₃). These bacteria, such as Rhizobium, live in the root nodules of legumes or in the soil, where they convert atmospheric nitrogen into a form that plants can use. Additionally, some free-living bacteria, like Azotobacter, also perform this nitrogen fixation in the soil. This process is essential for replenishing the nitrogen available to plants and, consequently, the entire ecosystem.
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, convert gaseous nitrogen into ammonia through a process called nitrogen fixation. This process helps make nitrogen available to plants for growth and is a key step in the nitrogen cycle.
There are no liters of hydrogen gas in gaseous ammonia. Ammonia (NH3) consists of nitrogen and hydrogen atoms, but the hydrogen is chemically bonded to the nitrogen.
The bacteria in the soil that can break down ammonia into gaseous nitrogen are primarily known as denitrifying bacteria. These bacteria, such as those from the genera Pseudomonas and Bacillus, convert ammonia (NH3) and nitrites (NO2-) into nitrogen gas (N2) or nitrous oxide (N2O) through a process called denitrification. This process is an essential part of the nitrogen cycle, helping to reduce excess nitrogen in the soil and return it to the atmosphere.
The production of ammonia from gaseous hydrogen and gaseous nitrogen will increase at a higher temperature. This is because the reaction is endothermic, meaning it requires heat to proceed. Higher temperatures provide the necessary energy for the reaction to occur more rapidly.
Certain bacteria, such as those in the genera Rhizobium and Azotobacter, convert atmospheric nitrogen (N₂) into ammonia (NH₃) through a process called nitrogen fixation. This ammonia can then be further transformed into nitrites (NO₂⁻) and nitrates (NO₃⁻) by other bacteria in the soil. While these nitrates can be taken up by plants, which humans consume, nitrogen itself in its gaseous form is not usable by humans without this conversion process.

Nitrogen fixation
Nitrogen in soil compounds can be released back to the air through processes like denitrification, where microbes convert nitrate (NO3-) into nitrogen gas (N2) or nitrous oxide (N2O) which is then released into the atmosphere. Another way is through ammonia volatilization, where ammonia (NH3) is converted into a gaseous form and released into the air.
Gaseous ammonia is a compound made of nitrogen and hydrogen with the chemical formula NH3. It is a colorless gas with a sharp, pungent odor and is commonly used in fertilizers, cleaning products, and industrial processes. Ammonia is also produced in nature through biological processes and is found in the atmosphere.
"fixation" (usually turning into ammonia)
The balanced equation for this reaction is: N2(g) + 3H2(g) → 2NH3(g).
Some bacteria living in symbiotic relationship in plant's roots fix gaseous nitrogen to ammonia. Also when plants or animals die, some bacteria decompose proteins to ammonia.
