Nitrogen fixation
Our atmosphere has 78% nitrogen gas.The atmospheric nitrogen gas cannot be utilised directly by the plants or animals.
The process of converting nitrogen gas of the atmosphere or air into compounds of nitrogen(which can be used by the plants)is callednitrogen fixation.
The nitrogen gas is the free nitrogen whereas nitrogen compounds are said to be fixed(converted into nitrogen compounds).
