“…Confirming the above argument, values for CO 2 production were lower than those found by Alves et al (2006) and Araújo et al (2009), who obtained mean values of approximately 239.5 and 120 mg m -2 h -1 CO 2 -C respectively when studying microbial activity by measuring soil respiration in fragments of dry tropical forest in the State of Paraíba. However, the similarity between day and night seen in this study differs from that obtained by the above authors, who found that the microbial activity estimated from the CO 2 production was higher during the night.…”

“…CO 2 emissions were evaluated by the method of C-CO 2 capture in sodium hydroxide solution adapted by Araújo et al (2009). The collection system consisted of the random distribution in each watershed of five cylindrical PVC buckets with a capacity of 12 L, arranged directly on the natural soil surface, to quantify combined CO 2 emissions from the activity of microorganisms and from the roots.…”

“…A medição da liberação de CO 2 do solo é fundamental no ciclo do Carbono nos ecossistemas. Ao quantificar o nível de atividade dos microrganismos do solo, pode-se compreender a velocidade de decomposição da matéria orgânica e a qualidade do solo (ARAUJO et al, 2009).…”
