Revista Brasileira de Agroecologia, Pelotas, v. 4, n. 2, p. 4240-4243, 2009.1980-9735http://repositorio.bc.ufg.br/handle/ri/14206The microbial biomass is an indicator soil quality, and proportionally smaller fraction of the soil organic C and it is a significant and potentially mineralizable N available to the plants., Therefore, this study goals to determine the biomass and soil microbial activity in two management systems. The experiment was conducted in organic production system in Fazendinha Agroecológica of Embrapa Rice and Bean, located in Santo Antônio de Goiás, GO. The attributes evaluation related to the quantity and activity of the soil (carbon and nitrogen in soil microbial biomass, basal respiration and metabolic quotient) showed significant difference between soil management systems. However, no significant differences between the soil coverage for some attributes studied, only for the metabolic quotient.porAcesso AbertoCarbonoNitrogênioQuociente metabólicoCarbonNitrogenMetabolic quotientArtigo
