There are many microorganisms in the environment that can provide benefits to plants. Among these, the best known are rhizobia, bacteria that associate with the roots of legumes and can provide the plant with all the nitrogen necessary for its development and production. The supply of nitrogen occurs through the process of Biological Nitrogen Fixation (BNF) where bacteria can obtain nitrogen from atmospheric air and make it available to plants in a symbiosis relationship.
The association of these microorganisms in the roots of soybean plants makes cultivation possible without the use of nitrogen fertilizers, as the entire nitrogen requirement is supplied by bacteria of the genus Bradyrhizobium. This is one of the main factors in the competitiveness of Brazilian soybeans in the world market, because if we did not have this technology we would have to use nitrogen sources of which 70 to 80% are imported, significantly increasing the cost of soybean production and possibly taking away our competitiveness in this regard. Marketplace.
O azospirillum is another genus of plant growth-promoting bacteria, which, due to their ability to biologically fix nitrogen and produce plant hormones, promote an increase in root volume and the absorption of nutrients and water. The benefits to plants provided by this genus led Embrapa researcher, Dr. Décio Gazzoni, to name them as “Good Bacteria”.

The use of “good bacteria” is a trend in Brazilian agriculture and could provide a sustainable form of production, with a reduction in the use of nitrogen fertilizers and an increase in profitability for rural producers.
