Pyrogenic C produced by the fire, due to its aromatic structure, may represent a C pool of small turnover rate and its addition to the soil may increase C sequestration and alter the SOM composition and dynamics. This study aimed to investigate the impact of vegetation burning on content and chemical composition of soil organic matter (SOM) along a profile of a sandy Acrisol in Southwestern Amazon, Brazil, within 3 years after burning (3Y).  aEnvironmental factors  aForest fires  aOrganic matter  aSandy soils  aImpacto Ambiental  aIncêndio Florestal  aMatéria Orgânica  aQueimada  aSolo Arenoso  aAcre  aAmazonia Occidental  aAmazônia Ocidental  aFactores ambientales  aIncendios forestales  aRio Branco (AC)  aSuelos arenosos  aWestern Amazon1 aLIMA, M.
