Students and educators looking for resources on the world of soil science will want to bookmark this useful site. Created by the United States Department of Agriculture's (USDA) Natural Resources Conservation Service, the site includes college-level appropriate material on soil biology, soil risks, soil quotations, and urban soil issues. The "Soil Risks & Hazards" area contains two key documents that can be best used by students seeking to understand potential soil-related hazards in and around different parts of the US. Moving along, "The Twelve Soil Orders" leads to a page created by the University of Idaho about the soil taxonomy created by the USDA in 1975. The "Soil Quotations" area has some rather compelling quotes from biologists, soil scientists, and poets about the nature and importance of soil. The site is rounded out by the "Agriculture in the Classroom" link, which leads to state agricultural profiles created by the USDA.
