O objetivo deste estudo foi avaliar as alterações no carbono orgânico do solo, na biomassa e atividade microbiana do solo, bem como na atividade de urease e fosfatase ácida, em dois tipos de solo de Cerrado, sob diferentes sistemas de manejo e uso do solo. O estudo constou de cinco sistemas de manejo e uso do solo em Neossolo Quartzarênico e de quatro sistemas em Latossolo Vermelho, além de áreas de referência sem alterações antrópicas nos dois solos. Os sistemas de manejo do solo promoveram alterações nos atributos bioquímicos, nos dois solos estudados, sendo que, no Neossolo Quartzarênico, a área sob a seqüência soja/braquiária provocou redução no carbono orgânico e no carbono da biomassa microbiana e aumento na respiração micobiana e no </span><span style="color: #000000;"><em>q</em></span><span style="color: #000000;">CO</span><span style="color: #000000;"><sub>2</sub></span><span style="color: #000000;">, enquanto, no Latossolo Vermelho, todas as áreas, com exceção da pastagem, promoveram reduções nos atributos bioquímicos avaliados.
