Study nitrogen-fixing microorganisms distributed in the environment: first of all, they are certainly free-living and symbiotic nitrogen-fixing bacteria, but also actinomycetes from the genus Frankia, etc.
Isolate and select active nitrogen-fixing strains with high effectiveness of nitrogen fixation.
Complete and create a strong collection of active strains of nitrogen-fixing microorganisms for their subsequent application in the production of biofertilizers and bioremediation of degraded lands.
