Hello friend
___________________________
The process of conversion of free nitrogen gas of the atmosphere into nitrogen compounds is called as nitrogen fixation.
It takes place in the Following ways::
⚫ ATMOSPHERIC NITROGEN FIXATION:
Lighting results in a reaction between nitrogen and oxygen present in the air to produce oxides of nitrogen
These oxides dissolve in rainwater forming Dilute nitric acid.
This nitric acid reacts with the alkalis of the soil ( like limestone) to turn into nitrates.
Ex... CaCO3 + 2HNO3 ===>>> Ca(NO3)2+H2O+ CO2
2NO+O2=2NO2
⚫ BIOLOGICAL NITROGEN FIXATION:
It is the conversion of atmospheric nitrogen into nitrogen compounds by living organisms.
Nitrogen fixing bacteria,called rhizobium are found in the root nudules of the leguminous plants.
They can fix atmospheric nitrogen into nitrates.
Thanks..

Hi there !!
The process of conversion of atmospheric nitrogen into water soluble nitrogen compounds called nitrates is called atmospheric nitrogen fixation.
it takes place in the following two ways :
1. Atmospheric nitrogen fixation
Lightning causes high temperature which. results in reaction between nitrogen present in the air with oxygen to form Oxides of nitrogen. These further get dissolved in rainwater forming dilute nitric acid, which is absorbed by plants easily.
Some reactions are
N2 + O2 = 2NO
2NO + O2 = 2NO2
2NO2 + H2O + O2 = 4HNO3
CaCO3 + 2HNO3 = Ca(NO3)2 + H2O + CO2
2.Biological Nitrogen fixation
It is the conversion of atmospheric nitrogen into nitrates by living organisms. Bacteria like Rhizobium, present in the root nodules of leguminous plants convert atmospheric nitrogen into water soluble nitrates.
