\title{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 \code{thionic} / sulfidic
material to disambiguate from naturally acidic Histosols.}
