Title:National Soil Characterization Database
Source:National Resources Conservation ServiceNational Cartography and Geospatial Center P.O. Box 6567 Fort Worth, TX 76115 phone: 1-800-672-5559 URL: http://www.ncg.nrcs.usda.gov
Description:This database from the Soil Survey Laboratory (SSL), National Soil Survey Center, contains analytical data for more than 20,000 pedons of U.S. soils and about 1,100 pedons from other countries. Standards morphological pedon descriptions are available for about 15,000 of these pedons. Most of this data were obtained over the past 40 years and about 3/4 of the data is less than 20 years old. Analytical data for most of the pedons is fairly complete, according to the prevailing view of the research and characterization needs when the pedon was sample.The National Soil Characterization Database is composed of the SSL working computer files. It includes data that may or may not represent the central concept of a soil series or map unit and pedons sampled to bracket a range of soil properties within a series of a landscape. For research purposes, all such data are retained in the database. Users unfamiliar with a given soil may want to consult a knowledgeable soil scientist to determine how well the data represents a soil series. Furthermore, the database has not been edited to remove all of the erroneous or sometimes misleading data. Users are responsible for the assessment of the accuracy and applicability of the data. |
