Soybean (Glycine max) is the most important aleuro-oleaginous cultivated in the world, being undoubtedly the crop that had most advanced in Brazilian agriculture, due to a series of joint factors such as the increase in productivity, producer efficiency, new technologies, especially in the southern and central regions of Brazil. For the 2020/2021 harvest, Brazilian soybean production is expected to break a new record, reaching 131 million tons. The use of bacteria that promote plant development helps to reduce cultivation costs, being an alternative to increase soybean crop yield. In the Brazilian agricultural scenario, soybean is able to maintain high yields in commercial crops inoculated with Bradyrhizobium japonicum and B. elkanii strains through the symbiosis between leguminous plants and N2 fixing bacteria. Thus, the objective of this revisional work is to investigate the inoculation technique in Brazilian soybean production and analyze its advances in the last decade. Inoculation is one of the most important practices in soybean cultivation, so the producer must inoculate the soybean to fix N2 and thus help in the production of nitrogen compounds for the plant, achieving greater productivity. Finally, the scientific studies analyzed show that the inoculation technique in Brazilian soybean farming has evolved a lot in the last years, significantly contributing to the increased production and productivity of the soybean crop.
