Abstract(s)
Understanding the vertical distributions of organic carbon (OC) is crucial for
predicting and simulating the influences of soil units on the terrestrial carbon
cycle. The OC in the fine earth fraction was calculated for the soil units
Anthrosols, Cambisols, Fluvisols, Leptosols, and Regosols in the municipality
of Ponte de Lima, Portugal, at depths of 0–30 cm, 0–100 cm, 0–200 cm, and
0–2590 cm. In the study area, over 40% of the OC is concentrated in the
Regosol unit, followed by the Anthrosols with over 23% OC at all depths, and
the Leptosols with over 22% OC at all depths. The soil units Cambisols and
Fluvisols have a lower representation in the territory, with values below 1.5%
and 6.5% respectively at all depths. The obtained results contribute to
assessing the potential of the soil units present in the municipality to
sequester CO2, promoting the development of carbon inventories and analyzing
the distribution of OC through accurate and reliable estimates of
current C reserves as an essential tool for analyzing and modeling the effects
of different factors involved in the potential of soil OC sequestration.
