Abstract Next Generation Technologies on DNA sequencing provide new approaches on environmental microbiology enabling us to launch new experiments to understand crucial issues such as sustainable production on agroecosystems. Currently, an international partnership between Brazil and Holland has been established by FAPESP and The BE-Basic Foundation (FAPESP/BE-BASIC 2011/51749-6) to prospect functional bioindicators for soil quality monitoring for sustainable management of sugarcane biomass production. In Brazil sugarcane conventional methods of harvesting which requires the field to set on fire has been forbidden. Thus, with mechanical harvesting, straw figures out as an important source of biomass which can also remain in the field and bring benefits to the system. However, few gaps avoid this practice to be widespread. The ideal amount of straw to be left in field is still unknown, und this can affect productivity. Efforts should be considered to overcome this challenge within the set deadline. Hence, it is necessary to understand straw decomposition as well as Green House Gases emission on sugarcane culture to evaluate its potential regarding sustainable resources management on agriculture. Earthworms are well known by their benefits to the ecosystem, recognized as bioindicators of land use, they also have been associated with GHGs emissions. The present work intends to explore relationship between different doses of straw and earthworms as a priming effect on soil microbiota to activate straw decomposition. Correlating molecular tools with other environmental factors (physical, chemical, biochemical, biological and GHG emission) from soil, it is proposed the development of a functional and taxonomic microarray for microbes related in straw decomposition.
