Diazotrophic research focuses on studying and understanding bacteria that have the ability to fix nitrogen gas from the atmosphere into a usable form for plants, a process known as nitrogen fixation. Diazotrophic bacteria play a crucial role in agricultural and ecological systems by enhancing soil fertility and promoting plant growth without the need for synthetic fertilizers. Researchers in this field investigate the diversity, ecology, and mechanisms of nitrogen fixation in diazotrophic bacteria, as well as their potential applications in sustainable agriculture and environmental remediation.
