Mollic thickness test (default >= 20 cm in v0.1)

WRB 2022 has more nuanced thickness criteria depending on whether the soil overlies continuous rock at <75 cm, but the simple absolute threshold is the predominant case for non-shallow soils. Cumulative thickness across multiple contiguous mollic-qualifying horizons is a v0.2 refinement.

Usage

test_mollic_thickness(h, min_cm = 20, candidate_layers = NULL)

Arguments

h

Numeric threshold or option (see Details).

min_cm

Numeric threshold or option (see Details).

candidate_layers

Numeric threshold or option (see Details).
