Kastanozem RSG gate (strengthened, WRB 2022 Ch 4, p 112)

Source: R/diagnostics-rsg-tier2.R
kastanozem_strict.Rd

Same structure as chernozem_strict but using the mollic horizon (no chernic gate) and starting \<= 70 cm of mineral soil surface.

Usage

kastanozem_strict(pedon, min_bs = 50, max_top_cm = 70, strict = NULL)

Arguments

pedon

A PedonRecord.

min_bs

Minimum base saturation % above the carbonate layer (default 50).

max_top_cm

Maximum depth of the carbonate layer below the mineral soil surface, cm (default 70).

strict

Logical or NULL. When NULL (default) it resolves via getOption("soilKey.rsg_strict", FALSE). TRUE raises the base-saturation floor to 75%.

Value

A DiagnosticResult recording whether the diagnostic is present, the qualifying layers, and the supporting evidence.

Tier-3 strict mode (v0.9.98)

With strict = TRUE the base-saturation floor above the carbonate-bearing layer is raised from 50% to 75%. The 70 cm carbonate-depth window is left unchanged.
