  1. Universal Soil Classification Jon Hempel Alex McBratney Erika Micheli IUSS USC Working Group International ASA/CSSA/SSSA Annual Meeting San Antonio, TX October 19, 2011

  2. “Bridging the Centuries” Conference in Gödöllő, Hungary-September 2009Declaration to “IUSS”(on the need for a Universal Soil Classification system)

  3. 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.

  4. Core Working Group Membership • Jon Hempel, Director-National Soil Survey Center, Lincoln, NE (Chair) • Erika Micheli, Head Department of Soil Science and Agricultural Chemistry SzentIstvan University Gödöllő,  Hungary (Co-Chair) • Alex McBratney, University of Sydney, Sydney, AU • Alfred Hartemink, ISRIC, Wagenigen, the Netherlands • Ben Harms, Department of Natural Resources, Indoorroopilly, QLD, AU • Curtis Monger, New Mexico State University • Ganlin Zhang, Chinese Academy of Sciences, Nanzing, China • Humberto Santos, Embrapra Solos, Rio de Janeiro, Brazil • John Galbraith, Virginia Tech University, Blacksburg, VA • Luca Montanarella, Action Leader, Joint Research Center, Ispra, Italy • Lucia Anjos, Federal Rural University of Rio de Janeiro (UFRRJ), Soils Department, Rio de Janeiro, Brazil • Method Kilasara, Faculty of Agriculture, Department of Soil Science, Tanzania • Micheal Golden, Director-Soil Survey Division, Washington, DC • Peter Schad, Department of Ecology and Ecosystem Sciences, TechnischeUniversitat, Munchen, Germany • Pavel Krasilnikov, Institute of Biology , Karelia Research Center RAS, Petrozavodsk , Russia • Phillip Owens, Assistant Professor, Department of Agronomy, Purdue University, West Lafayette, IN • Sergey V. Goryachkin, Institute of Geography, Russian Academy of Sciences, Moscow, Russia

  5. 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 future

  6. Considerations for a Universal Soil Classification System • Simplification • ST example • User community • Enable others??? • Anthropogenic concerns (erosion, compaction, drainage, siltation, etc) • Numeric/continousclassification

  7. 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 system

  8. 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 Anjos

  9. 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 Galbraith

  10. 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 McBratney

  11. 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 Galbraith

  12. 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
