The use of biofertilizers has been increasing in recent years, as they provide a reduction in the use of chemical fertilizers, as well as promoting plant growth, biological nitrogen fixation and phosphorus solubilization, triggering greater crop productivity and impacting the soil health. Symbiotic bacteria can be further divided into associative (forming nodules, for example) or free-living. All nitrogen-fixing bacteria are diazotrophic and may or may not be symbiotic. Among the various bacteria, those of the genus Azospirillum, Pseudomonas and Bacillus, have provided several benefits for forage grasses. The benefits arising from the use of plant growth-promoting bacteria can be diverse and can contribute to forage growth, enabling improved nutrient acquisition through phosphorus solubilization, biological nitrogen fixation, synthesis of phytohormones and production of siderophores. The use of these bacteria promotes plant growth, in addition to contributing to a sustainable agricultural system, improving productivity and production efficiency. However, it is extremely important to advance research related to the use of biofertilizers in tropical pastures.
