  abstract = {{T}ropical environments are considerable contributors to overall soil carbon loss to the atmosphere. {L}and use effects on soil chemical attributes have been well documented mainly in humid environments; however, less attention has been paid to the changes in soil enzymatic activities in dry ecosystems that is a sensitive indicator in ecological processes, due to its importance in soil dynamics and microbial activity. {T}he present study is part of interdisciplinary project that investigated the effect of land cover type and seasonal variation on absolute and specific enzymatic activities per unit of soil organic carbon ({SOC}) and per microbial biomass carbon ({MBC}). {W}e assessed five different land use type ({T}ropical dry forest-{TDF}, protected area with {A}ngico -{ANA}, protected area with {I}pe-{TAB}, {S}crub area-{SCR} and agricultural area with maize-{M}) and five areas of each land use in three layers: 0-0.05, 0.05-0.10 and 0.10-0.20 m. {T}he samples were collected at rainy season 1 in {A}pril 2014 ({RS}1), dry season {O}ctober 2015 ({DS}) and rainy season 1 {A}pril 2016 ({RS}2). {T}he conversion of the preserved area provided a reduction in absolute enzymatic activities, especially in the {SCR} and {M}. {T}he reductions were of 76% for beta-glucosidase, 95% for urease and 72% for acid phosphatase. {T}he specific enzymatic activities per unit of {MBC} increased with the change of soil use, except in {M}. {T}he enzymatic activity per unit of {SOC} in the {TDF} area was higher in relation to the other areas evaluated, except for specific activity of acid phosphatase. {T}he land use type influenced the absolute and specific soil enzyme activities, but not show a clear trend of seasonal effect.},
