The key processes of biogeochemical cycling of nitrogen are: 1. Nitrogen Fixation 2. Ammonification 3. Nitrification 4. Denitrification. 1. Nitrogen Fixation: Nitrogen fixation is a process of conversion of gaseous form of nitrogen (N2) into combined forms i.e. ammonia or organic nitrogen by some bacteria and cyanobacteria. There are free-living as well as symbiotic microorganisms […]
