  abstract = {{T}he {C}aatinga biome has been severely devastated over the years due to the replacement of native dry forests with grassland areas in the {B}razilian semiarid region. {D}espite this, variations in key soil quality indicators still need to be fully elucidated. {W}e evaluated soil and root respiration dynamics in grassland ({GR}), agroforestry ({AS}), and {C}aatinga forest ({CA}) areas, during dry and rainy seasons. {I}n situ, monthly {CO}2 flux (total, root, and heterotrophic respirations), soil moisture (theta v), and temperature ({T}soil) were measured. {S}oil samples were collected every 5 cm layer up to 20 cm depth to analyze total organic carbon ({TOC}) and microbial activities. {T}he highest parameter values occurred during the rainy season. {T}otal soil respiration was highest in {AS}, followed by {CA} and then {GR}, with 19.3, 13.4, and 8.4 ton {C} ha-1 yr-1, respectively, and root respiration contributed 33.2 and 32.9% to total soil respiration in {CA} and {AS}, respectively. {H}owever, {TOC} concentrations and microbial activity were significantly higher in {AS} than in {GR} and similar to {CA}, more than compensating the {C} losses by respiration. {T}herefore, agroforestry systems have a high potential for semiarid lands because they preserve soil carbon and microbial activity comparable to {C}aatinga forests.},
