Nitrogen fixation or biological nitrogen fixation (BNF) is a chemical process by which molecular nitrogen (N 2), which has a strong triple covalent bond, is converted into ammonia (NH 3) or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. The nitrogen in air is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or diazotrophy is an important microbe-mediate…
