Nitrogen is sourced from the atmosphere, where it makes up about 78% of the air we breathe. It can also be found in soil, water, and organic matter. Additionally, nitrogen can be obtained from synthetic sources such as fertilizers and industrial processes.

Natural Sources:
- Biological Nitrogen Fixation:
- Bacteria and archaea in soil, water, and plants convert atmospheric nitrogen gas (N2) into ammonia (NH3) and other nitrogen compounds.
- Examples: Rhizobium bacteria in root nodules of leguminous plants (e.g., beans, peas)
- Lightning and Atmospheric Fixation:
- Electrical discharges in the atmosphere convert N2 into nitrogen oxides (NOx), which dissolve in rainwater and are carried into the soil.
- Volcanic Activity:
- Nitrogen-rich gases are released during volcanic eruptions.
- Decomposition of Organic Matter:
- Bacteria and fungi break down plants and animals, releasing nitrogen into the environment in the form of ammonia and nitrates.
Anthropogenic Sources:
- Industrial Processes:
- Fertilizer production (e.g., the Haber-Bosch process) converts N2 into ammonia-based fertilizers.
- Combustion of fossil fuels (e.g., coal, oil, gas) releases nitrogen oxides into the atmosphere.
- Agriculture:
- Excessive use of nitrogen fertilizers can lead to nitrogen runoff and pollution.
- Livestock manure and sewage also contribute to nitrogen release.
- Transportation:
- Vehicle exhaust releases nitrogen oxides into the atmosphere.
Other Sources:
- Seawater:
- Nitrogen is present in seawater in the form of nitrates, nitrites, and dissolved N2.
- Hydrothermal Vents:
- Nitrogen-rich fluids are released from hydrothermal vents on the ocean floor.
