Fixation processes free up nitrogen atoms from their diatomic form to be used in other ways, but nitrogen does not easily react with other chemicals to form new compounds.
The most common method of industrial nitrogen fixation is the Harber - Bosch process, which requires extremely harsh conditions, 200 atm of pressure and 400 °C of temperature.
Applications considered in the process included bio-mining; nitrogen fixation by engineered crops; gene drive propagation in populations of invasive species; and engineered seeds and plants destined for distribution to the public.
The process is called nitrogen fixation, and it occurs in microorganisms on the roots of plants.
Thus, in addition to the so - called «Haber - Bosch process of nitrogen fixation,» nitrogenase also stimulates a reaction corresponding to the «Fischer - Tropsch synthesis of hydrocarbons,» which can be used on a large scale to synthesize fuels, for instance from industrial waste gases..
Some, however, plow through the night, converting nitrogen from the air into usable nutrients — a process known as nitrogen fixation.
This anthropogenic addition of nitrogen has reached a magnitude comparable to about half of global ocean nitrogen fixation (the natural process by which atmospheric nitrogen gas becomes a useful nutrient for organisms).
«Fifty - four percent of that is fertilizer — the Haber - Bosch process; 11 percent is atmospheric deposition — the plus side of pollution; 18 percent is in situ fixation,» or nitrogen - fixing cover crops, like legumes, Sanchez said.
Key climate - relevant biogeochemical processes such as calcification, primary production and nitrogen fixation are investigated using a large array of techniques, ranging from molecular tools to physiological and ecological approaches.
The overall process is called nitrogen fixation.
«More than 60 genes involved in various processes of heterocyst formation and nitrogen fixation were assigned to the chromosome based on their similarity to the reported genes,» Kaneko's team writes in Genome Research.
The main nitrogen compartment is atmospheric N2 (Supplementary Table 1), which is almost inert and can only be transformed into bioavailable forms (e.g., NH3) via highly energetic processes (e.g., lightning, the Haber — Bosch process, or biological fixation of N; 30).
