  abstract = {{T}he {B}razilian dry forest occupies an area of about 1 million km(2) approximately 46% of which has been deforested. {M}any studies have been done on the effects of this on productivity and soil chemical attributes. {H}owever, little is known about soil enzymatic activity, which is sensitive to environmental changes. {T}he objective of this study was to evaluate the effects of deforestation using different levels of human disturbance on soil enzyme activities, organic carbon content, microbial biomass, and microbial community. {W}e studied areas covered with forest ({TDF}), old grass ({OG}), or new grass ({NG}). {S}oils from {NG} had increased microorganisms, which restored important processes related to carbon, sulfur, and nitrogen cycling, so that they resembled those in the forested area. {T}he results of this study showed that the conversion of forest to pasture with a high level of human disturbance could decrease the activities of beta-glucosidase, urease, alkaline phosphatase, and fluorescein diacetate in the soil by up to 87%, 66%, 62%, and 58%, respectively. {T}hese findings suggest that human disturbance can cause substantial changes in the enzymatic activity and microbial community in the soil. {W}e suggest that maintaining grass pasture with low human disturbance should have fewer impacts on soil quality.},
