The Soil Survey Laboratory (SSL), National Soil Survey Center
(NSSC) is responsible for providing accurate and reliable soil characterization
data for the National Resources Conservation Service (NRCS) National Cooperative
Soil Survey (NCSS) Program. The SSL data are provided in reports, e.g., Primary
and Supplementary Characterization Data Sheets and in various electronic forms,
including tapes, disks, and CD-ROMs. These reports are the end product of the
analytical system and are a means to transmit information to the users of these
data. It follows that these data reports must be complete, accurate, and
understandable. In addition, these reports provide historical documentation for
future reference.
Pedon characterization data, or any soil survey data, are more
appropriately used when the operations for collection, analysis, and reporting
these data are thoroughly understood. The purpose of this document is to
describe the SSL characterization data reports to maximize user understanding of
these data. This document is not intended as an interpretive guide for
soil characterization data.
