PAIVA, Artur Orelli; REZENDE, Alba Valéria  and  PEREIRA, Reginaldo Sergio. Carbon stock in cerrado sensu stricto in the Federal District. Rev. Árvore [online]. 2011, vol.35, n.3, pp.527-538. ISSN 0100-6762.

The objective of this study was to estimate the carbon stock of the aerial section (stems, branches and litter) and belowground (roots and soil) of woody vegetation in a cerrado sensu stricto located on Água Limpa Farm, at University of Brasilia, Federal District, Brazil. The studied area was sampled from 20 x 50m plots, allocated systematically. In each plot, it was uplifted all the woody shrubby-arboreous individuals, being live and stand dead, with at least 5 cm of diameter taken at 30 cm from the ground level. It was also performed collections of litter biomass, roots biomass (fine, medium and thick) and density and soil carbon concentration. The maximum depth adopted for collection of belowground section was 2 meters. Most of the carbon corresponded to soil compartment (88.7%), which was much more than the roots (7.3%), where the concentrations were 271.23 and 22.38 tons per hectare, respectively. Stems and branches totalized 8.60 tons of carbon per hectare and litter, 3.62 tons of carbon per hectare.

Keywords : Carbon stock; Biomass; Cerrado sensu stricto.
