The effects of forest fires on soils depend on many factors, among which are the recent history of the area and in particular, the fuel load, the type of vegetation, its continuity, etc. We have little research that studies the effects of silvicultural management treatments in order to reduce the risk of new fires and mitigate their effects. In the present study, three different silvicultural treatments applied in an area that was affected by fire for the last time in Ódena in 2015 are evaluated. These treatments were: M05 (managed 10 years before), M15 (managed just before the fire), and NM (without management). The following edaphic parameters were analyzed: contained organic carbon (CO), microbian biomass carbon (CMB), basal edaphic respiration (REB), the relationship between both (qCO2) and the enzymatic activities β-Glucosidase (β-Glu) and phosphatase (PHP). It was observed that the fire was somewhat more severe in the area treated in 2005 (M05). The NM management produced higher carbon values of the microbian biomass, but a decrease in the enzymatic activities with respect to M05 and M15. So a clearing treatment leaving the remains on the ground influences the severity of the fire. However, the changes observed in the different managements are not as relevant as for those who suspect serious problems to the functioning of the soil.
