The Twelve Soil Orders
Soil Taxonomy
|
 |
In 1975, Soil Taxonomy was
published by the United States Department of Agriculture's Soil Survey
Staff. This system for classifying soils has undergone numerous changes
since that time, and the 2nd edition was published in 1999. Soil Taxonomy
remains one of the most widely used soil classification systems in
the world.
At the highest level, Soil Taxonomy places soils in one of 12 categories
known as orders. We have put together a collection of information
and images to illustrate the distribution, properties, ecological
significance, and use of these 12 soil orders.
