The role of nitrogen-fixing archaea in biofertilizers is still being studied as of my most recent knowledge update in September 2021, and their practical application in agriculture is not yet well-established. However, like nitrogen-fixing’s bacteria and cyanobacteria, nitrogen-fixing’s archaea have the potential to contribute to biofertilizers.
In biofertilizers, nitrogen-fixing archaea may play several roles.
The genetic ability of nitrogen-fixing archaea to transform atmospheric nitrogen (N2) into ammonia (NH3) or ammonium (NH4+), making nitrogen available for plants, is the basis for biological nitrogen fixation. For the soil to be enriched with nitrogen, a crucial ingredient for plant growth, this biological nitrogen fixation process is necessary.
Increased variety of nitrogen-fixing microorganisms in the soil can be achieved by including nitrogen-fixing’s archaea into biofertilizers.
Different nitrogen-fixing’s microbes, including archaea, may thrive under particular soil circumstances thanks to their ability to adapt to such conditions. In soils where conventional nitrogen-fixing’s bacteria encounter difficulties, incorporating archaea into biofertilizers may be advantageous.
Using nitrogen-fixing archaea in biofertilizers could lessen the need for synthetic nitrogen fertilizers, encouraging more environmentally friendly agricultural practices and reducing negative effects like nitrogen leaching and greenhouse gas emissions.
