Guides for Soil Interpretations and Qualities

The purpose of this table is to provide links to national and local guidance criteria for soil interpretations and qualities. Many of these links are to the National Soil Survey Handbook (NSSH); some are links to supplemental guides containing local criteria that may be used in lieu of the national criteria in the NSSH. Use of local criteria is encouraged for NASIS interpretations and qualities, but the user is cautioned to not use any supplemental guide outside of the geographic area for which it was developed.

If you have additional or updated supplemental guides, please submit them to the MLRA Region 9 Staff.
