Applying Agronomic Principles of Rhizobial Inoculation to the Conservation of a Keystone Legume Species in a High Mountain Ecosystem on an Oceanic Island

Inoculation with specific Bradyrhizobium strains significantly enhances the growth, survival, and nitrogen fixation of Spartocytisus supranubius, a keystone legume species in Teide National Park. The study demonstrated that inoculated plants exhibited higher nodule formation, biomass, and water content, both under greenhouse conditions and in field trials. This approach not only accelerates plant development but also improves stress resilience, offering a promising strategy for the conservation of this threatened species. By leveraging rhizobial inoculation—a technique traditionally used in agronomy—the research provides a novel method to support ecosystem stability in nitrogen-poor high-mountain environments.
