The National Soil Survey Handbook (NSSH) is a subdivision of the NRCS directives system. It consists of parts 600 through 659 of Title 430, Soil Survey. The NSSH provides the main operational and procedural guidance for conducting the NRCS portion of the National Cooperative Soil Survey program.
Several part numbers are intentionally omitted to allow for expansion. The format is intended to allow flexibility for additions and updates and to provide an overall structure for all soil survey handbooks within the 600 series of the NRCS directives system.
Staff at the National Soil Survey Center in Lincoln, Nebraska, are the primary editors of the NSSH. Comments or questions on this handbook should be addressed to the National Leader for Soil Survey Standards at the National Soil Survey Center.
