This table provides links to national and local guidance criteria for property data. Many of these
links are to the National Soil Survey Handbook (NSSH).
Some soil properties have 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.
