Azospirillum sp. and mycorrhizal fungi: key microorganisms in sustainable agriculture

Abstract

The role and importance of two types of soil microorganisms are highlighted: the bacteria of the Azospirillum genus and mycorrhiza-forming fungi, which establish beneficial interactions with plants and the application of these generates great interest due to the potential and to be considered as these soil microorganisms as a tool in sustainable and agroecological agriculture. The importance of developing biofertilizers with native strains of plant-promoting microorganisms, such as Azospirillum brasilense and mycorrhizal fungi, is also highlighted as a strategy to control diseases and improve the agronomic performance of crops. The development and application of this type of biofertilizers can be considered an important alternative for the partial or total replacement of mineral fertilizers, which would generate great benefits without having a detrimental impact on the environment.
