"Soils in the Environment "

The following web links come from a variety of sources. Every effort has been made to only list sites which your instructors think might be helpful and that appear to originate from reliable sources. However, web sites may become outdated, deactivated, or even change in content entirely. Endorsement of any organizations, companies, individuals or products, or assurance of absolute accuracy should not be implied by them being listed here. In other words "Browse at Your Own Risk" and remember that this material is supplementary material simply provided as another resource for you.  If you have any problems with, or questions about, any of the sites listed please contact your instructor. They have been arranged roughly into relevant categories for your lab course and for exploring the field of soil science in general.
