“Bridging the Centuries” Conference in Gödöllő, Hungary-September 2009
Declaration to “IUSS”
(on the need for a Universal Soil Classification system)Slide3
IUSS Council Approval of USC Working Group from the minutes of IUSS Council, Brisbane, AU, August 2010
The
Working Group on Universal Soil Classification was agreed with a time limit of 8 years (2018) and a review of progress towards an agreed Soil Classification System after 4 years (2014), with an interim document report in 2012.Slide4

Slide5
Ways forward for a Universal Soil Classification System
Very positive responses from many sectors of soil scientific community
IUSS Backing
Growing interest in soil science information
We need not start from scratch
Needs for the futureSlide6
Considerations for a Universal Soil Classification System
Simplification
ST exampleUser communityEnable others???
Anthropogenic concerns (erosion, compaction, drainage, siltation, etc)
Numeric/
continous
classificationSlide7
Task Groups
Accept diagnostic criteria from existing systems
Chair: Erika Micheli
Determine the appropriate categorical level at which to start classification
Chair: Pavel Krasilnikov
Need a profile (
pedon
) classification systemSlide8
Task Groups
Compare guidelines for field profile descriptions (
redox, structure, color, consistency, texture, etc.)
Propose a standardized nomenclature
Chair: Peter Schad (Reinhold
Jahn
)
Compare and compile horizon nomenclature, designations, definitions
Propose a standardized nomenclature
Chair: Curtis Monger and Lucia AnjosSlide9
Task Groups
Larger user groups than the current systems
Chair: Luca Montanarella
Dual (parallel) nomenclature that includes and accommodates both a scientific and non-technical language (English lay / Texas vernacular)
Chair: John GalbraithSlide10
Task Groups
Recommend laboratory methods and correlation rules
IUSS Liaison: Alfred Hartemink
Explore other diagnostics (e.g. soil biology)
IUSS and NCSS soil ecology Liaison: Alfred Hartemink
Explore other observation methods (e.g. spectroscopy, gamma
radiometrics
)
Chair: Alex McBratneySlide11
Explore data and knowledge acquisition for soils (
pedons
) from Earth and other planets and depths greater than 2 m (e.g. Anthropogenic, Urban, Subaqueous, Paleosols, Other planets)
Chair: John GalbraithSlide12
Contemporary soil classification systems (including Soil Taxonomy) are very poor for topsoil assessments
Ochric
horizon is a “garbage can” for different topsoil types
USC should take into account the real diversity of topsoils of the world
