Resumo(s)
Soil organic carbon (SOC) is the major carbon (C) stock of the terrestrial
biosphere with great importance for the balance of C at the global scale. So, a
reliable estimate of the stored C in the mineral soil pool of forest ecosystems is of
great importance. Inventory information on SOC stocks is very scattered, because of
the inherent large spatial variability and the need of enormous sampling efforts.
Therefore, traditional broadleaves species, less representative in the global context
and scattered, as chestnut (Castanea sativa Mill.), are poorly sampled. Thus, this
study was carried out to estimate the soil organic carbon (SOC) stock in traditional
forests of sweet chestnut, based on in situ observations, to know the real contribution
of this type of forests to the SOC stocks. This research was developed on old
chestnut high forests for quality timber production submitted to a silviculture
management close-to-nature located in Northern Portugal. At this stage the stands
are close to self-thinning. Samples from soil profile at depths 0-10 cm, 10-30 cm and
30-60 cm were collected in 2002 and 2012. Besides the objective to know the real
contribution of this type of forests to the SOC stocks, the evolution of the C storage
was studied to also analyze the general capacity of the site concerning its
sustainability and soil carbon pool. The cumulative amount of SOC shows an
increase of 9% over 2002 in Marão and an increase of 4% in Bornes.
