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 2009 Declaration to “IUSS” (o n 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 Szent Istvan 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, Technische Universitat, 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/continous classification

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
