Aceric qualifier (ae): pH (1:1 H2O) <= 5 in some layer within the upper 50 cm. Used for sub-aerially exposed acid-sulfate soils (Solonchaks, Gleysols on former tidal flats). v0.9.1: numeric pH gate only; v0.9.2 adds the cross-check against thionic / sulfidic material to disambiguate from naturally acidic Histosols.
