For thogh we slepe or wake, or rome, or ryde, Ay fleeth the tyme; it nil no man abyde. (1390 Chaucer Clerk’s Tale 1. 118)
“Time and tide wait for no man”Slide5
Soil Science, unlike many other disciplines, does not have a Universally accepted Classification System.(About 50 different soil classification systems globally)
Efforts Made by
FAO-World Soil Classification
WRB
Soil Taxonomy
Many Others
This Goal Has
NOT
been achievedSlide6
Time for a Universal Soil Classification SystemMost Natural Sciences have
Common Classification System
Botany
Anthropology
Astronomy
Natural Classification Systems are
Accepted & used Globally
“Soil Classification” is viewed as a National System yet to have international acceptanceSlide7
is to provide a
Common Understanding & Language for Communication
Common Reasons Given
For a Universal System Slide8
Time for a Universal Soil Classification SystemInternational
Politics “
That Hampered Collaboration”
Over last Century
- Personalities
have
“Mellowed”
Movement has been for more “Harmony”
Time is Ripe for Acceptance of
Standard Soil Terminology
Standard ClassificationSlide9
“Bridging the Centuries” Conference in Gödöllő, Hungary-September 2009Declaration to “IUSS”Slide10
Bridging the Centuries“Declaration”
Soil Science Lacks Commonly Accepted & Used Terminology
Field Descriptions & Laboratory Standards
Soil Characterization
Soil Correlation & Classification
Making Communication & Data Exchange Difficult Slide11
Bridging the Centuries “Declaration”
There is a Need to Develop a
“Universal Soil Classification”
System For the Effective
Transfer of Soil InformationSlide12
Time for a Universal Soil Classification System
International Multi-Categorical Soil
Systems
FAO
- Legend for
“Soil
Map
of the World”
Three levels (Very Apt for Scale > 1:5,000,000)
There are Many Difficulties for National Mapping
WRB
- Maintained by IUSS Working Group
Flexible System with Flat Hierarchy
Serves as
“Tool for Correlation”Slide13
Time for a Universal Soil Classification System
-
SOIL
TAXONOMY
–
hierarchical
system built on the 1938 soil classification system
Linkage to:
“National Cooperative Soil Survey Program”
Important Tool for Many to Buy into the System
Maintained “Soil Series” conceptSlide14
Time for a Universal Soil
Classification System
Building a new USC Consider
Adopting:
The Best of the Most Modern Systems
Use Conceptual Diagnostic Approach
Established Terminology
Account for Continuous Classes (DSM)Slide15
Time for a Universal Soil Classification SystemWe Need a Starting Place
Use the Most Documented Existing Systems
Use System with the Highest Amount & Most Accurate Data to support the Science
Need to Share Existing Documentation
Need an Accepted Approach – One that is Fair & Based on Best Science of Today
Need an Accepted Group of Experts & Leaders Internationally to Bind DecisionsSlide16
Time for a Universal Soil Classification System
We Should be Aware of New Developments
Numerical
Classification Concepts developed over last 30 years should be Investigated
If appropriate Incorporated into the System
Pedo-taxonomic Distance
Numerical Polythetic Allocation
Continuous Classes (digital soil mapping)Slide17
Time for a Universal Soil Classification System
“Success of any Universal System”
Must be Dynamic, Flexible & Innovative
Continuously Used
Continuously Tested
Classification should not be just a Name
to Make the System More PowerfulSlide18

Time for a Universal Soil Classification System
Recommendations
Request to IUSS Secretary General for
USC Working Group
– (approved WCSS, 2010)
Consider a Universal Soil Classification &
Other Soil Survey Standards
Decide on Categories and Classes
Standards shared with all Nations
Focus on
“Use & Management”
Slide21
Time for a Universal Soil Classification System
Recommendations
Establish Core Group of Scientists
Responsible for Binding Decisions into the Universal Soil Classification System
Chair –Jon Hempel, Vice Chair-Ericka Micheli
Buy In - To
“Established Systems”
Borrow the
“Best of each National System”
Nations to Continue
“Existing Systems”
During USC DevelopmentSlide22
Time for
A
Universal Soil
Classification
System
1.
Need to Build the Roadmap/Framework
of System
2.
Work with Countries Around the World
3.
Invite Working Group to USA for Meeting in 2011
Slide23
Time for a Universal Soil Classification System
Summary
A Universal
Soil Classification System is
Feasible
Will have International
AcceptanceToday the Opportunity Arises forThe Current Generation to Collaborate and
“
Realize this Dream”Slide24
