Nitrogen fixation involves the conversion of atmospheric nitrogen into ammonia and organic derivatives, by natural means, especially such conversion, by microorganisms (nitrogen fixing bacteria) in the soil, into a form that can be assimilated by plants.
The easily accessible form by which nitrogen can be obtained by plants is nitrates, as they are very soluble in soil water and easily picked by plant root vessels
