The importance of organic farming has increased through the years to promote food security allied with minimal harm ecosystem. Besides environmental benefits, a recurring problem associated management is unsatisfactory yield. A possible solution may rely on soil microbiome, which presents crucial role in system. Here, we aimed evaluate bacterial community structure and composition under conventional farming, considering tropical climate soil.Our treatments were composed by composted poultry manure green Bokashi. Both based low nitrogen inputs. We evaluated high-throughput sequencing 16S rRNA genes, fertility, enzyme activity two systems, one last transitional from organic.We observed that both systems this study, have higher yield than treatment, even year drought conditions. These results are highly correlated changes chemical properties enzymatic activity. attributes pH, Ca, P, alkaline phosphatase, β- glucosidase positively while K Al treatment. Also, our show bacteria community, being phyla Acidobacteria, Firmicutes, Nitrospirae, Rokubacteria most abundant. biochemical helping increase crop yields.Different (the so-called natural use distinct sources), shift composition, implying their functionalities. contributed identification target groups trophic system, contribute yields.
