Nitrogen Fixation is the conversion of airborne nitrogen into nitrates, mainly by bacteria mainly in the soil. Nitrogen has little biological use, nitrates are food to other plants.

nitrogen fixation : The biological or chemical process by which elemental nitrogen, from the air, is converted to organic or available nitrogen.

Nitrogen fixation The conversion of atmospheric (or dissolved) nitrogen gas into nitrate by microorganisms.

Nitrogenous oxygen demand (NOD) The amount of oxygen required to oxidize any ammonia present in a water.

Nitrogen fixation
Conversion of atmospheric nitrogen gas into forms useful to plants and other organisms by lightning, bacteria, and blue-green algae; it is part of the nitrogen cycle.
Nitrogen Oxide ...

It is cycled between air and soil by means of the nitrogen cycle which includes a process known as nitrogen fixation. Nitrogen fixation may take place through either industrial (fertilisers) or natural processes.

From this association, the host plant may gain usable ammonia from unusable atmospheric nitrogen through a process called nitrogen fixation (N2 -> NO3 and NH4). The bacteria gain a home and a steady source of food from the host plant.

Conversion of nitrogen to water-soluble forms such as ammonia and nitrates is called nitrogen fixation. Nitrogen Leaching A detrimental environmental effect and a type of pollution resulting from the application of nitrogen fertilizers on plants.
