| Zusammenfassung |
| The tropical forests of the Amazon Basin occur on a wide variety of
different soil types reflecting a rich diversity of geologic origins and
geomorphic processes. We here review the existing literature about the
main soil groups of Amazonia, describing their genesis, geographical
patterns and principal chemical, physical and morphologic characteristics.
Original data is also presented, with profiles of exchangeable cations,
carbon and particle size fraction illustrated for the principal soil types;
also emphasizing the high diversity existing within the main soil groups
when possible. Maps of geographic distribution of soils occurring under
forest vegetation are also introduced, and to contextualize soils into an
evolutionary framework, a scheme of soil development is presented having as
its basis a chemical weathering index. We identify a continuum of soil
evolution in Amazonia with soil properties varying predictably along this
pedogenetic gradient. |
