Resolve a crop name (Italian or English) to its canonical entry

NFert reference tables (uptake_table, mas.table, crops.table, standard_pk_doses.table) carry the canonical English crop names in the column crop (since NFert 0.12.0), with the Italian translation in crop_it and a duplicate of the English name in crop_en for backward compatibility. This helper accepts any of the three forms (case-insensitive, whitespace-normalised, exact match) and returns the canonical English key used for joins downstream.

Usage

resolve_crop(x, table = NFert::uptake_table)

Arguments

x: Character. Crop name in Italian or English.
table: Lookup table; default NFert::uptake_table.

Value

Character. The canonical crop name (English, as in the crop column).

Details

If the input matches none of the columns, the input is returned unchanged together with a warning.

Examples

resolve_crop("Durum wheat (grain)")
#> [1] "Durum wheat (grain)"
resolve_crop("Grano duro (granella)")
#> [1] "Durum wheat (grain)"
resolve_crop("Mais trinciato classe 700")
#> [1] "Silage maize (class 700)"
