Soil survey information is regularly updated and posted to the Web Soil Survey, which is the official source for current information. The Web Soil Survey provides both tabular and spatial data and allows you to create a custom soil resource report for your specific area of interest. In the table below, clicking on a survey area that is listed as "current" takes you to the Web Soil Survey.
Supplemental information is available in the form of published soil surveys. USDA has published soil surveys since 1899. Many of these publications are archived as PDF files. In the table below, clicking on a survey area that is listed "yes" for "Archived PDF online" takes you to a link to the files. Most of the archived soil surveys include detailed soil maps. For more information on accessing the maps, click here.
Printed copies of soil surveys are available at Federal depository libraries and in some cases at USDA offices. For information about reference copies (CD or paper) of a publication or for information about publications that are not on the following list, contact the State Conservationist.
