Abstract

The study of organic matter of 16 forest podzols of Tierra del Fuego (Argentina), from chemical fractionation of soil carbon revealed that, while there is a high amount of slightly humified organic matter in surface horizons, which is closely related to fertility and sustainability of these forest ecosystems and very unprotected against climate or human impact, podzolization seems to be playing a key role in the accumulation of carbon through humified forms of low lability and its protection against the degradation by organometallic complexing, so that, under apreliminar perspective, it could be assumed that the podzolic soils of sub-Antarctic forest area of South America are working as real carbon sinks.
