\description{
WRB 2022 Ch 5 / Ch 4 Histosols + Cryosols + Technosols (variable pages):
substances at concentrations toxic to plant roots. Practical proxy:
very low pH (<= 3.5, sulfuric / hyperacidic) OR very high electrical
conductivity (>= 16 dS/m, equivalent to Salic) OR specific contamination
fields (heavy metals, hydrocarbons) which the soilKey schema does not
yet model. v0.9.33 v0 implementation uses pH <= 3.5 OR EC >= 16 dS/m.
