Nitrogen Fixation

As we have said before, atmospheric nitrogen cannot be used by plants or animals. It has to be first fixed. The term nitrogen fixation refers to the oxidation or reduction of atmospheric nitrogen to nitrates (NO-3) and ammonia (NH3) which can be used by living organisms. In nature nitrogen fixation into these compounds occurs primarily in two ways:

  • High energy fixation
  • Biological fixation
