Abstract

he amount of stored organic carbon in the forest soil depends, among other factors, on the quantity of organic litter left after the application of the silvicultural treatments during the different stages of forest growth. Considering the above, the objective of this study was to evaluate the quantity of the soil organic carbon (SOC) stored at two soil depths (0-20 cm and 20-40 cm) as a response to the application of a liberation cutting, four thinning and a seed tree regeneration method applied to different stands, effects that were contrasted against a control 60-year old stand. The results indicate that SOC ranged from 60.0 to 115.6 Mg ha-1 for the 0-20 cm soil depth and from 39.5 to 76.5 Mg ha-1 to the 20-40 cm soil depth. All the stands stored more SOC than the control, which registered an average accumulated reserve of 99.5 Mg ha-1. The liberation cutting presented the highest reservoir with 192.1 Mg ha-1. Changes in the vegetation cover caused by the cut intensities applied directly influence SOC reserves. In general, the Cambisol soils are good SOC reservoirs where the MDS was applied.
