Re: Require sources of Soil Taxonomy Expert System

Much of the information we have available is posted under on our web site. The specific information you requested is under ""Standards for Soil Survey"".
http://www.statlab.iastate.edu/soils/nssc/

The Soil Survey Manual is out of print and only available as an electronic version at this time. This publication is our standard for describing soil profiles.
http://www.statlab.iastate.edu/soils/ssm/gen_cont.html

Soil Taxonomy is our standard for soil classification. It is also available under ""Standards for Soil Survey"" http://www.statlab.iastate.edu/soils/nssc/

Information on other classification systems is available at:
http://www.itc.nl/~rossiter/research/rsrch_ss.html

I hope this information is useful to you.
