Annotate KSSL/NASIS pedons with a derived WRB Reference Soil Group

Applies usda_to_wrb_rsg to each pedon's USDA classification (preserved as site$reference_usda + site$reference_usda_suborder by load_kssl_pedons_gpkg) and writes the result to site$reference_wrb_from_usda – a "best-guess" expected WRB label for benchmark comparison.

Usage

annotate_wrb_from_usda(pedons)

Arguments

pedons

List of PedonRecord objects.

Value

The same list, with site$reference_wrb_from_usda populated where USDA classification is present.

Details

Pedons that already have site$reference_wrb populated (e.g.\ from external sources) are left untouched.
