Assign each crop to its soil-carbon crop group.

Source: R/soc_crop_groups.R
soc_crop_group.Rd

Map item_prod_code and an irrigation flag to the crop group the soil carbon balance marches: cropland_rainfed_herbaceous, cropland_irrigated_herbaceous, or one group per woody species such as cropland_rainfed_olive (the species slug comes from Name_biomass, the column the source implementation builds its category from, so it is "Olive" rather than the names_cats key "Olives"). Every label keeps the cropland_ prefix, which is what lets the balance recognise a group as cropland for its soil-cover curve, its C:N lookup and its water term without enumerating groups.

Usage

soc_crop_group(
  item_prod_code,
  irrigated = FALSE,
  vocabulary = whep::items_prod_full
)

Arguments

item_prod_code

Integer vector of FAOSTAT production item codes.

irrigated

Logical vector, recycled: is the area irrigated?

vocabulary

The crop vocabulary, a tibble with item_prod_code, Herb_Woody and Name_biomass. Defaults to items_prod_full.

Value

A character vector of group labels, one per input element. An item with no Herb_Woody classification aborts, naming it: an unclassified crop silently pooled into the wrong group would move carbon between groups with nothing recording it.

Examples

soc_crop_group(c(15L, 260L, 260L), irrigated = c(FALSE, FALSE, TRUE))
#> [1] "cropland_rainfed_herbaceous" "cropland_rainfed_olive"     
#> [3] "cropland_irrigated_olive"
