The Manual (issued in March 2017) 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. It contains extensive information describing each soil property and the proper procedures for observing or measuring it in the field.
Although the Manual is intended primarily for use by soil scientists engaged in making soil surveys, those with limited soil science experience or less familiar with soil survey procedures can also use the information.
