Abstract Slash‐and‐burn clearing of forest typically results in increase soil nutrient availability. However, the impact these nutrients on microbiome is not known. Using next generation sequencing 16S rRNA gene and shotgun metagenomic DNA , we compared structure potential functions bacterial community soils to deforested Amazon region related differences chemical factors. Deforestation decreased organic matter content factors linked acidity raised pH base saturation exchangeable bases. Concomitant expected changes factors, observed an alpha diversity microbiota relative abundances putative copiotrophic bacteria such as Actinomycetales a decrease taxa Chlamydiae Planctomycetes Verrucomicrobia soils. We did observe genes microbial metabolism increases repair, protein processing, modification, degradation folding functions, might reflect adaptation characteristics due clear‐cutting burning. In addition, there were composition groups associated with metabolism‐related functions. Co‐occurrence network analysis identified distinct phylogenetic patterns for suggested relationships between aluminium content, Actinobacteria nitrogen sources The support taxonomic functional adaptations following deforestation. hypothesize that may serve buffer drastic fertility after slash‐and‐burning deforestation region.
