Nitrogen Fixation

Domain	Definitions
Food & Agriculture	The conversion of elemental nitrogen(N2)from the atmosphere to organic combinations or to forms readily utilisable in biological processes. Source: European Union. (references)
Mining	A. Extracting nitrogen from the air in commercial quantities for use in agriculture or industry. b. In a soil, the conversion of atmospheric nitrogen to a combined form by the metabolic processes of some algae, bacteria, and actinomycete. (references)
Public Administration	The use of atmospheric nitrogen in the manufacture of commercially important nitrogen compounds, nitric acid, ammonia and ammonium salts, and mainly used as fertilizers. Conversion to ammonia is effected by the Haber process, and nitric acid is obtained by the oxidation of ammonia. Bacteria present in the roots of certain plants fix atmospheric nitrogen; so do Azotobacter, free-living soil micro-organisms, though the latter are inefficient and play only a small part in regulating the soil nitrogen balance. Some metal complexes interact with N2 to give N2 complexes which may be reduced to NH3. The return of the fixed nitrogen to the atmosphere is denitrification. Source: European Union. (references)
Weather	Conversion of atmospheric nitrogen gas into forms useful to plants and other organisms by lightning, bacteria, and blue-green algae; it is part of the nitrogen cycle. (references)

Specialty Definition: Nitrogen fixation

Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N₂) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).

Nitrogen fixation is performed naturally by certain types of anaerobic bacteria. Legumess such as clover contain symbiotic bacteria of this type within nodules in their root systems, producing nitrogen compounds that help to fertilize the soil. See George Washington Carver.

Nitrogen can also be artificially fixed for use as fertilizer or in other industrial processes. The most popular method is by the Haber process. Artificial fertilizer production has achieved such scale that it is now the largest source of fixed nitrogen in the Earth's ecosystem.
