\description{
WRB 2022 Ch 5 / Ch 4 Histosols (p 96): organic material formed under
the influence of rainwater only (NO surface or groundwater input).
Distinguished from Rheic by its low pH (rainwater is naturally
acidic and unbuffered) and low base saturation. Practical proxy:
Histosol Order with weighted-mean pH_h2o <= 4.5 in the upper 100 cm
AND no carbonates (calcaric / calcium-rich evidence absent).
