Abstract	Sludge from Effluent Treatment Stations (ETS) has great potential for nutrition and high amount of organic material, which makes it possible to use as a conditioner of the soil and in agricultural crops. However, the sludge may be subject to polluting agents and appropriate control management is required. As microorganisms play a role in the transformation and decomposition of organic matter and have a good response to environmental changes, it is very important to study the biological attributes of the soil through its use. The aim of this work was to evaluate the influence of different doses of sewage sludge from ETE on the soil microbiological attributes. The experiment was conducted at the IFBA Soil Laboratory, Vitória da Conquista BA campus and at the Southwest Bahia State University, Vitória da Conquista BA campus. The soil used was the dystrophic Red Yellow Oxisol. In the assay, a Completely Randomized Design (CRD) was used, with five doses of sludge from Vitória da Conquista BA, subdivided into five proportions: 0; 4; 8; 16 and 32 Mg / ha with three replications. Three soil biological indicators were determined: Basal Soil Respiration (BSR), the microbial biomass carbon (MBC) and the metabolic quotient (qCO2). According to the results, it can be observed that the 32 Mg / ha treatment showed the highest increase in RBS, MBC and qCO2.
