The Nitrogen Cycle Through Nature - ThoughtCo
WebMar 30, 2024 · Nitrogen is fixed, or combined, in nature as nitric oxide by lightning and ultraviolet rays, but more significant amounts of nitrogen are fixed as ammonia, nitrites, and nitrates by soil microorganisms. More than 90 percent of all nitrogen fixation is effected … nitrogen cycle, circulation of nitrogen in various forms through nature. Nitrogen, … WebA relatively small amount of ammonia is produced by lightning. Some ammonia also is produced industrially by the Haber-Bosch process, using an iron-based catalyst, very high pressures and fairly high temperature. ...
