covered by a Eutric Endoluvic Amphialbic Stagnosol (Anosiltic, Endoloamic, Humic). The map unit will be named as follows: First map scale level: dominant: Luvisols codominant: Stagnosols Second map scale level: dominant: Stagnic Luvisols codominant: Albic Stagnosols Third map scale level: dominant: Albic Stagnic Luvisols codominant: Luvic Albic Stagnosols Remarks: The use of the depth-related specifiers is not recommended in map legends, where generalization is required. At every scale level, elective qualifiers may be added. If one wants to give, e. g., information about organic carbon, one can do that even at the first map scale level and write: dominant: Luvisols (Ochric) codominant: Stagnosols (Humic) If somebody wants to give additional information on soil genesis, this can also be done on the first map scale level: dominant: Luvisols (Stagnic) codominant: Stagnosols (Luvic) Both in combination would read, e. g., at the second map scale level: dominant: Stagnic Luvisols (Ochric) codominant: Albic Stagnosols (Luvic, Humic) References IUSS Working Group WRB: World Reference Base for Soil Resources, fourth edition.
