Abstract Soil carbon sequestration in agriculture may provide offsets for fossil fuel emissions. The activity and composition of the soil microbial community regulates the conversion of plant carbon into soil organic matter. Thus changes in the microbial community or its activity may provide opportunities to enhance C sequestration. This study will investigate the microbial activity, microbial biomass C and N, aggregate C, 13C and soil enzymes in integrated system of Urochloa and eucalyptus. The design will completely randomized in a factorial 2 × 4 with three replications. The system consists of 2 eucalyptus hybrids: Grancam 1277 and Urograndis H13 and Urochloa brizantha in integrated, spaced 2 m between plants and 12 m between eucalyptus lines, introduced in 2009 in Votuporanga, SP, Brazil. The collection will be held in august 2016 in four sampling sites: on the canopies of eucalyptus, 2 meters from the eucalyptus line, four meters of eucalyptus line and 6 meters of eucalyptus line, using the pasture in full sun as a reference in 0-0.05 and 0-0.10 and 0.10-0.20 deeps.
