The carbon of microbial biomass is a good indicator to soil changes. This work had the objective of evaluating the effect of organic residue burning on soil microbial biomass carbon content (C-bio) in area cultivated with corn. The evaluations were conducted 90 and 130 days after the emergency (dae). For 90 dae, the burning of residues increased the C-bio, while in the evaluation of 130 dae the burning of residues had no effect. Among the evaluations made to the 90 and 130 dae, the burning of residues reduced the C-bio.
