\title{Hyposulfidic material (WRB 2022 Ch 3.3.9): same inorganic sulfidic S and
field pH as hypersulfidic but does NOT consist of hypersulfidic (criterion 3
-- does not acidify to pH < 4 on aerobic incubation, usually self-neutralised
by carbonate). Reachable from v0.9.128: when \code{incubation_ph} is measured,
a sulfidic + pH>=4 layer that stays >= 4 on incubation is the set-complement
of \code{\link{hypersulfidic_material}} and is reported here. Without an
incubation pH the two cannot be told apart, so this returns empty (the layer
is reported as potential hypersulfidic instead).}
\usage{
hyposulfidic_material(pedon, min_s_pct = 0.01, min_pH = 4)
}
\arguments{
\item{pedon}{A \code{\link{PedonRecord}}.}

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

\item{min_pH}{Numeric threshold or option (see Details).}
}
\value{
A \code{\link{DiagnosticResult}} recording whether the diagnostic is present, the qualifying layers, and the supporting evidence.
