Tests whether any horizon meets the gypsic horizon criteria. The gypsic horizon is a horizon of secondary gypsum accumulation, diagnostic for Gypsisols.
Arguments
- pedon
A
PedonRecord.- min_thickness
Minimum thickness in cm (default 15).
- min_gypsum_pct
Minimum gypsum percent in fine earth (default 5).
Details
Sub-tests called:
test_caso4_concentration– gypsum >= 5%.test_minimum_thickness– thickness >= 15 cm.
v0.2 limitations: the WRB rule that gypsum content must exceed the underlying horizon by 1% (absolute) is not enforced. Petrogypsic (cemented) horizons are not yet detected. Both deferred to v0.3.
