Official Soil Series Descriptions (OSD)
Introduction
“Official soil series description” is a term applied to the
description approved by the Natural Resources Conservation Service that defines
a specific soil series in the United States. These official soil series
descriptions are descriptions of the taxa in the series category of the national
system of classification. They mainly serve as specifications for identifying
and classifying soils.
While doing survey work, field soil scientists should have all the existing
official soil series descriptions that are applicable to their soil survey
areas. Other official soil series descriptions that include soils in adjacent or
similar survey areas are also commonly needed. Scientists in other disciplines,
such as agronomists, horticulturists, engineers, planners, and extension
specialists also use the descriptions to learn about the properties of soils in
a particular area.
Additional information about the establishment and maintenance of official
series descriptions can be found in the
National Soil Survey Handbook, Part 614.06.
