Report on the VII International Conference and Field workshop on
Paleopedology
"Memory of ancient landscapes and living body of present ecosystems"
by Erika Micheli
The meeting took place in Florence, Italy, 7-11 June 2004. It was a joint meeting of the Commission of Soil Genesis and the
Commission of Paleopedology of IUSS, the International Union of Quaternary Research and the Working Group of the World
Reference Base for Soil Resources. Papers and posters were presented following sessions:
1. Recognizing paleopedological processes;
2. Classification of paleosols and soils of reclaimed anthropic areas in World Reference Base and Soil Taxonomy and
comparison between the different systems
3. Evaluating soilscape dynamics on paleosols and anthropic soils
4. Building soil typological units on paleosols and anthropic soils
5. Mapping techniques for paleosols and anthropic soils
6. Managing the old and anthropic surfaces
The conference was followed by a 3-day fieldtrip in Tuscany. The observed soils (including Nitisols, Luvisols, Vertisols,
Albeluvisols, Regosols, Calcisols) were very well prepared and documented, and provided a good opportunity for intensive
discussions, in particular on genesis and classification
The major conclusions of the meeting:
* Nomenclature of horizon designation needs to be extended to indicate certain processes (ferric, stagnic)
* Field identification of current hydrological properties needs to be developed
* Indication of processes that are not active any more (e.g. cryogenic, argic when there is no more clay translocation) on
the qualifier level is needed.
* Harmonization with Soil Taxonomy is needed (in many cases even the concept is different : e.g. Fragipan and Fragic
horizon)
Thanks to the Organizing Committee for the great meeting!
