Cyanobacteria, also known as blue-green algae, are significant nitrogen fixers in various environments, including waterlogged paddy fields. They convert atmospheric nitrogen gas (N₂) into usable nitrogen compounds (like ammonia) which are essential nutrients for rice plants.
The nitrogen fixation in a paddy field is brought about by
