\title{Sideralic properties (WRB 2022 Ch 3.2.13)}
\usage{
sideralic_properties(pedon, max_cec_per_clay = 24, max_bulk_cec = 2)
}
\arguments{
\item{pedon}{A \code{\link{PedonRecord}}.}

\item{max_cec_per_clay}{Numeric threshold or option (see Details).}

\item{max_bulk_cec}{Numeric threshold or option (see Details).}
}
\value{
A \code{\link{DiagnosticResult}} recording whether the diagnostic is present, the qualifying layers, and the supporting evidence.
}
\description{
Mineral material with a relatively low CEC. WRB 2022 (3.2.13) requires
BOTH:
\enumerate{
  \item one or both of: clay >= 8\% AND CEC/clay < 24 cmol_c/kg clay; OR
        bulk CEC < 2 cmol_c/kg soil;
  \item evidence of soil formation as defined in criterion 3 of the cambic
        horizon (\code{test_cambic_soil_formation}).
}
Both must be met by the SAME layer. Criterion 2 was added in v0.9.127
(previously only criterion 1 was enforced); where the soil-formation
evidence cannot be assessed (no Munsell/clay/Fe/carbonate adjacency data)
the result is \code{NA} rather than a false positive.
