Abstract
The objective of this work was to study the mineral and organic components of
soils from 4 sites, located in The Ferreira Penna Scientific Station (ECFPn), Par6
State, Brazil: a) Sandy Yellow Latosol under primary forest b) Clayed Yellow
Latosol under primary forest c) a medium textural Yellow Latosol under
secondary vegetation (capoeira), d) Archaeological Black Earth. The Latosols
present the typical characteristics of the predominant Amazonian soils.
Djfferences in carbon content between the first three sites is likely to be more
closely related to the variation in drainage between the sites rather than
topography and vegetation cover or soil parent material. The Archaeological
Black Earth has contrasting characteristics in com
