Nov 26, 2025 · Nitrogen fixation, any natural or industrial process that causes free nitrogen, which is a relatively inert gas plentiful in air, to combine chemically with other elements to form more-reactive …

Fixed nitrogen is essential to life on Earth. Organic compounds such as DNA and proteins contain nitrogen. Industrial nitrogen fixation underpins the manufacture of all nitrogenous industrial products, …

Aug 15, 2023 · Nitrogen fixation involves a set of natural and artificial processes that convert nitrogen into a form organisms can use. Nitrogen is an essential component of amino acids, proteins, and …

Feb 17, 2023 · Atmospheric nitrogen fixation or only nitrogen fixation is when atmospheric nitrogen (N 2) is converted to ammonia (NH 3). It is carried out primarily by soil microorganisms.

Nov 7, 2025 · The meaning of NITROGEN FIXATION is the conversion of atmospheric nitrogen into a combined form (such as ammonia) through chemical and especially biological action (such as that of …

Aug 4, 2025 · Nitrogen fixation is a vital natural and biochemical process that converts inert atmospheric nitrogen gas (N₂) into biologically usable forms such as ammonia (NH₃), ammonium (NH₄⁺), or nitrate …

Nitrogen fixation is a natural and industrial process that transforms atmospheric nitrogen gas (N2) into more chemically reactive forms, such as ammonia (NH3) or nitrates (NO3-).

Nitrogen fixation is a key step in the nitrogen cycle, as it transforms inert atmospheric nitrogen into ammonia that plants can use. Without this process, plants would struggle to obtain the essential …

Nitrogen fixation definition: any process of combining atmospheric nitrogen with other elements, either by chemical means or by bacterial action: used chiefly in the preparation of fertilizers, industrial …

May 19, 2025 · Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia (NH3) or related nitrogenous compounds in soil. Atmospheric nitrogen is molecular …
