Soil characteristics and microbiota, field-monitored for two years, showed that different water velocities originated diverse responses to rainfall; altered oxygenation and nutrient conditions resulted in differentiated carbon availability and cycling. The facies with lower carbon and water content supported a 35% less active but 3?4 timesmore efficientmicrobiota. Higher soil moisture in the silty facies (67%) led to increased carbon (12-fold) degradation and availability (3-fold), but not higher biomass. Soil and environmental conditions apparently rule microbiota metabolic state, hence the need to evaluate them as microbial growth support.  amicrobial activity  aCarbon cycling  aCarbon degradation  aHydraulic properties  aResidual tropical soil  aSoil microbiota1 aVARGAS JUNIOR, E. do A.1 aANTUNES, F. dos S.1 aMONTHÉ, G.
