Nitrogen Fixing Bacteria in Sustainable Crop Production
Year: 2025
Type: article
Abstract: The environmental damage and economic cost associated with excessive chemical fertilizer usage have heightened the need for sustainable farming methods. Nitrogen-fixing bacteria (NFB) provide an ecologically benign alternative by turning atmospheric nitrogen into plant-usable forms, minimizing the need for synthetic inputs. These microorganisms include symbiotic species such as Rhizobium, Bradyrhizobium, and Frankia, associative bacteria like Azospirillum, and free-living nitrogen fixers like Azotobacter. Their importance goes beyond nitrogen fixation to promote soil fertility, plant development, and ecological resilience. This page discusses nitrogen fixation methods, bacterial diversity, and applications in sustainable agricultural production. It also discusses problems and potential approaches, including biotechnology treatments to improve nitrogen fixation in non-leguminous crops. It also discusses problems and potential approaches, including biotechnology treatments to improve nitrogen fixation in non-leguminous crops. Integrating NFB into farming systems is a viable strategy to reduce pollution, increase crop output, and promote food security worldwide.
