  abstract = {{N}atural regeneration may be a cost-effective method for recovering areas previously used for intensive agricultural purposes. {P}lant diversity in the succession periods has been well documented; however, less attention has been paid to the changes in soil attributes, which may work as an instrument for the validation of regeneration methods. {T}he present study is part of a broader interdisciplinary research project assessing the effects of natural regeneration on biodiversity and the quality of the soil. {W}e investigated the effects of natural regeneration on the physicochemical attributes of the soil, as well as on soil organic carbon ({SOC}), microbial biomass carbon ({MBC}) and enzyme attributes. {W}e assessed three stages and five areas of each natural regeneration stage (early-{ER}, intermediate-{IR} and late-{LR}) in two layers: 0-5 and 5-10 cm. {T}he present study found a 20% {SOC} increase due to natural regeneration. {I}n the first layer, {SOC}, urease, acid phosphatase and arylsulfatase absolute activities were significantly higher in the two older natural regeneration stages ({IR} and {LR}) than those found in the {ER} stage. {W}e found a reduction in specific enzyme activities per {SOC} unit in the {ER} areas. {N}atural regeneration influenced {SOC} and {MBC}, the absolute enzyme activities, and the specific enzymes per {SOC} unit, mainly in the surface layer. {T}he present study provided some of the first data concerning the beneficial effects of natural regeneration on the quality of soil as measured through enzyme activity, {SOC} and {MBC} in a tropical dry region in {N}ortheastern {B}razil.},
