The Caatinga biome has been severely devastated over the years due to replacement of native dry forests with grassland areas in Brazilian semiarid region. Despite this, variations key soil quality indicators still need be fully elucidated. We evaluated and root respiration dynamics (GR), agroforestry (AS), forest (CA) areas, during rainy seasons. In situ, monthly CO2 flux (total, root, heterotrophic respirations), moisture (θv), temperature (Tsoil) were measured. Soil samples collected every 5 cm layer up 20 depth analyze total organic carbon (TOC) microbial activities. highest parameter values occurred season. Total was AS, followed by CA then GR, 19.3, 13.4, 8.4 ton C ha−1 yr−1, respectively, contributed 33.2 32.9% respectively. However, TOC concentrations activity significantly higher AS than GR similar CA, more compensating losses respiration. Therefore, systems have a high potential for lands because they preserve comparable forests.
