However, there is still a gap in our knowledge about the effects of PyOM over longer temporal scales, especially in field experiments that last longer than one cropping cycle. This thesis aims to study interactions between PyOM and soil organic carbon (SOC) and symbiotic patterns in soybean (Glycine max) under tropical field conditions in a sandy ferralsol in northeast Brazil.  asoil amendments  asoil fertility  asoil organic matter  aFertilidade do Solo  aAlterações do solo  aMatéria orgânica do solo  aMicorrizas arbusculares vesiculares  aSequestro de carbono no solo  aSoil carbon sequestration  aVesicular arbuscular mycorrhizas
