The 2022 Pocket Guide to Hydric Soil Field Indicator is taken from Version 8.2 of the NRCS Field Indicators of Hydric Soils in the United States released in 2018 and has incorporated changes made by the National Technical Committee on Hydric Soils through March 16, 2022. The indispensable Simplified Keys to Hydric Soil Indicators for all ten USACE Regional Supplements (developed by Phil Scoles, Terra Science, Inc.) at the end of the Pocket Guide have been updated and we have also added a key for contrast determinations.
