\title{Horizonte B latossolico (SiBCS Cap 2, p 57-59; v0.7 strict)}
\usage{
B_latossolico(
  pedon,
  min_thickness = 50,
  max_cec_per_clay = NULL,
  engine = NULL,
  ...
)
}
\arguments{
\item{pedon}{A \code{\link{PedonRecord}}.}

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

\item{max_cec_per_clay}{Numeric threshold or option (see Details).
Defaults to \code{NULL} (engine-aware): 17 in soilkey engine
(the SiBCS-loose threshold, slightly more permissive than
strict WRB ferralic 16) or 20 in aqp engine (v0.9.68 regional
tolerance for Embrapa lab methodology offset).}

\item{engine}{One of \code{"soilkey"} (default) or \code{"aqp"};
\code{NULL} reads \code{getOption("soilKey.diagnostic_engine")}.
Forwarded to \code{\link{ferralic}}.}

\item{...}{Reserved for future arguments.}
}
\value{
A \code{\link{DiagnosticResult}} recording whether the diagnostic is present, the qualifying layers, and the supporting evidence.
}
\description{
Adicionalmente a \code{\link{ferralic}} (WRB), o B latossolico
SiBCS exige:
\itemize{
  \item Espessura minima de 50 cm;
  \item Textura francoarenosa ou mais fina;
  \item Estrutura granular muito pequena/pequena ou em blocos
        subangulares fraco/moderado;
  \item < 5\% volume mostrando estrutura da rocha original;
  \item Ki \\<= 2.2 (geralmente \\<= 2.0);
  \item Cerosidade no maximo pouca e fraca.
}
v0.7 enforce thickness, texture, e ausencia de estrutura primaria
herdada via designation e clay; Ki/Kr quantitativos sao v0.8 (precisa
de SiO2/Al2O3 lab-data nao no schema).
