the qualifiers and the specifiers and the rules for the sequence of the codes for naming soils and creating map legends. Chapter 7 is the list of references. The seven chapters are followed by six annexes: Annex 1 is a field guide. It provides all field characteristics (including their definitions) needed for WRB classification and some additional general field characteristics. The characteristics are explained with many figures, and a flow chart is offered for hand texturing. Annex 2 lists the laboratory methods. This is only a list; it is not a laboratory manual. Annex 3 presents horizon and layer symbols for soil description. The field guide and the horizon and layer symbols are newly added to the WRB Manual and are meant to replace the FAO Guidelines for Soil Description (2006) for the use with WRB. Annex 4 is a soil description sheet. It is a separate document in the form of an excel file to fill in the surveyed field characteristics. Annex 5 provides a guidance for database set-up (not yet published). Annex 6 suggests colours in maps showing the RSGs. These suggestions follow roughly the colour choices in the atlases edited by the Joint Research Centre of the European Commission. List of the Reference Soil Groups according to WRB 2022 This is the list of the 32 Reference Soil Groups in the sequence of the key (Chapter 4 of the WRB Manual), including the codes (Chapter 6 of the WRB Manual). This list is mainly taken from Table 2 (Chapter 1) of the WRB Manual. Soils with thick organic layers HS Histosol (with thick organic layers) Soils with strong human influence AT Anthrosol (with long and intensive agricultural use, often altered to enhance fertility) TC Technosol (containing significant amounts of artefacts) Soils with limitations to root growth CR Cryosol (permafrost-affected) LP Leptosol (thin or with many coarse fragments) SN Solonetz (with a clay-enriched subsoil with high concentrations of exchangeable Na) VR Vertisol (high contents of shrink-swell clays, alternating wet-dry conditions) SC Solonchak (high concentrations of soluble salts) Soils distinguished by Fe/Al chemistry GL Gleysol (groundwater-dominated, underwater or in tidal areas) AN Andosol (with allophanes and/or complexes of Al and organic matter) PZ Podzol (subsoil accumulation of organic matter and/or oxides) PT Plinthosol (accumulation and redistribution of Fe) PL Planosol (stagnant water, abrupt textural difference) ST Stagnosol (stagnant water, no or only moderate textural difference) NT Nitisol (low-activity clays,
