In the nitrogen cycle, bacteria fix nitrogen from the atmosphere to form ammonia. This ammonia can then be converted into nitrites and nitrates by other bacteria in the soil, which plants can absorb to use for growth. Nitrogen eventually returns to the atmosphere through denitrification by bacteria.
Nitrogen can be removed from the atmosphere through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that plants can use. Nitrogen can also be removed through lightning strikes, which can combine nitrogen molecules with oxygen to form nitrogen oxides that are washed out of the atmosphere by rain.
It definitely does have an atmospheric component. When organic material is decomposed some of the microorganisms involved in doing this, called denitrifying bacteria, extract the nitrogen from the organic material and put it back in the atmosphere. Other bacteria take nitrogen from the atmosphere and convert it into substances that plants can use. Thus the atmosphere serves as an enormous pool of nitrogen for life. Please see the wikipedia article about the nitrogen cycle for more information.
Nitrogen gas in the atmosphere is taken up by certain soil bacteria, called nitrogen-fixing bacteria, which convert it into a form that plants can use, such as ammonia. Plants then absorb this nitrogen from the soil through their roots and use it to make proteins and other essential molecules. Some plants, like legumes, have a symbiotic relationship with nitrogen-fixing bacteria, while others rely on nitrogen from decaying organic matter or nitrogen-containing fertilizers.
Nitrogen fixation by bacteria: Certain bacteria like Rhizobium and Azotobacter convert atmospheric nitrogen into ammonia, which can then be used by plants. Lightning: Electrical storms can break down nitrogen molecules in the atmosphere, leading to the formation of nitrogen oxides that can eventually be washed down to the earth by rain. Industrial processes: Human activities such as combustion and industrial processes can release nitrogen oxides into the atmosphere, contributing to nitrogen deposition on land and water bodies.
Denitrification by bacteria
In the nitrogen cycle, bacteria fix nitrogen from the atmosphere to form ammonia. This ammonia can then be converted into nitrites and nitrates by other bacteria in the soil, which plants can absorb to use for growth. Nitrogen eventually returns to the atmosphere through denitrification by bacteria.
The bacteria that can release nitrogen from nitrates and nitrites in the soil back to the atmosphere are called denitrifying bacteria.
Most of the nitrogen that bacteria use comes from the atmosphere in the form of nitrogen gas (N2). Some bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen into a form that can be used by other organisms, such as ammonia or nitrate.
Nitrogen is returned to the atmosphere through the process of denitrification, where bacteria convert nitrates in the soil back into nitrogen gas. This process completes the nitrogen cycle as nitrogen is released back into the atmosphere as a gas.
Nitrogen-fixing bacteria do reduce the amount of nitrogen in the atmosphere by converting N2 into ammonia.
Several bacteria can fix the nitrogen fom atmosphere.

Bacteria in the soil called nitrogen-fixing bacteria go through a process called nitrogen-fixation which allows nitrogen to enter the atmosphere
they help balance the level of nitrogen in the soil and atmosphere.
Certain types of bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen gas (N2) into a form that can be used by plants and other organisms. These bacteria form symbiotic relationships with leguminous plants, such as peas and beans, and help them to absorb nitrogen from the air.
Soil bacteria are not responsible for fixing nitrogen from the atmosphere. This process is carried out by nitrogen-fixing bacteria like Rhizobium and cyanobacteria.
