Soil Survey Manual

The newly updated Soil Survey Manual, USDA Handbook No. 18, provides the major principles and practices needed for making and using soil surveys and for assembling and using related data. The Manual serves as a guiding document for activities of the National Cooperative Soil Survey (NCSS). Previously published in 1937, 1951, and 1993, the Soil Survey Manual is one of the defining documents for soil survey in the world.
