Elactrical discharge:- nitrogen can also be fixed into the soil during lightening and thunderstorm,where the atmospheric nitrogen combines with oxygen to form nitogen(ii)oxide then it then undergoes futher oxidation to form nitrogen(iv)oxide which then combines with rain water to form nitrous(HNO2)or nitric acid (HNO3) which futher dessociate to form nitrate
Other process off nitrogen fixation are:-
Symbiotic nitrogen fixation e.g rhizobium leguminosarium
Non symbiotic nitrogen fixation E.g azotobacter clostridiun
Ammonification nd nitrification
Under this there are many process involved E.g
Ammonificatiom I.e decay of animals or plant
Nitrification I.e conversion of organic matter to nitrite by nitrosomonas
Then oxidation of nitrite to nitrate by nitrobacter
When it COMBINES with oxygen (and it is quite difficult, the reactions being slow in the extreme), nitrogen oxides are produced. ... The atmosphere is approx 78% nitrogen and 21% oxygen. However with some extra energy like lightning then you get oxides of nitrogen which eventually form nitric acid and nitrates.
