WebBiological Nitrogen Fixation. BNF is a very valuable alternative to N fertilizer ( de Bruijn, 2016 ). It is a route in which N 2 in the atmosphere is converted into ammonia by prokaryotes using an enzyme complex (Nitrogenase), and an N pool is maintained in the ecosystems, which replenishes N losses. BNF occurs naturally in the soil by N fixing ...
