Test for any layer with caco3_pct above a (low) threshold — test_carbonates

Default threshold is 0.01% – effectively "any measurable secondary carbonate". Used to distinguish Phaeozems (no carbonates within 100 cm) from Chernozems and Kastanozems.

Usage

test_carbonates_present(h, min_pct = 0.01, candidate_layers = NULL)

Arguments

h: Numeric threshold or option (see Details).
min_pct: Numeric threshold or option (see Details).
candidate_layers: Numeric threshold or option (see Details).
