The European humus forms reference base 2014

A renewed European classification of humus forms is proposed taking decidedly the structure of the well-shared Word reference base for soil. Divisions, Classes and Groups of references and dozens of prefixes and suffixes should be able to sort out and describe a large part of top-soils of the planet. The 3 Divisions are composed of 11 Morpho-Functional Classes, 5 Terrestrial (Mor, Moder, Mull, Amphi and Tangel), 5 Semi-terrestrial (Mor, Moder, Amphi, Mull and Anmoor) and 1 Para (Para). The Classes are then detailed in 31 Groups of References, 16 Terrestrial, 14 Semi-terrestrial and 1 Para. Prefixes and suffixes allow the punctual description of a particular pedological Reference within each Group. The part of the preceding version (2011) is enriched in bibliographic references and results; photographs and tables allow also a better survey of the soil profile in the field.
