\description{
WRB 2022 Ch 5 (Nitisols / Ferralsols): "Containing layers with
>= 18\% Fe2O3 (or 12.6\% Fe) in fine earth, averaged over upper
100 cm or to a contact / petroplinthic / pisoplinthic / R."
}
\details{
Implementation: weighted mean of \code{fe_dcb_pct} (DCB-extractable
Fe2O3, the canonical Fe-pool for Ferralic / Nitic chemistry) over
the upper 100 cm.
