विवरण:For this study quantified the amount of dry biomass accumulated in litter, dead wood biomass and the amount of soil organic carbon (SOC) in four forest successional stages: 5 to 15 years, 15 to 30 years, over 30 years old and primary forest. A simple random design with sub-sampling, four treatments (successional stage), five repetitions (PPM) and four samples per PPM was established. The accumulated biomass in litter was higher in primary forests with 9,75 t ha-1, followed by forests over 30 years with 7,93 t ha-1, 15-30 years with 5,97 t ha-1 and finally forests 5-15 years with 5,60 t ha-1. The values of biomass in dead wood were of 7,80 t ha-1 in primary forests, 3,26 t ha-1 in forests older than 30 years, 5,84 t ha-1 in 15-30 year forests and 3,42 t ha-1 in 5-15 year forest. The soil organic carbon was higher in forests over 30 years (109,24 tC ha-1), followed by primary forest (92,29 tC ha-1), 15-30-year forest (88,01 tC ha-1); lastly, 5-15-year forest (78,48 tC/ha-1). There were statistical differences (α = 0,05) in biomass of accumulated litter on forest forests 5-15 years. The trends show an increase in the amount of biomass accumulated in litter with increasing successional stage. Dead wood biomass showed no statistical differences in age of the forest (α = 0,05). The soil organic carbon (SOC) showed statistical differences (α = 0,05) in forests of 5-15 years for forests older than 30 years.
