Build the bedding straw supply reaching the managed manure chain.

Converts the bedding destiny of crop residues (calculate_residue_destinies()'s residue_bedding_dm_t) into the dry matter, carbon and nitrogen that add_manure_bedding() adds to the housed manure streams. Composition comes from the same bio_coefs residue coefficients calculate_npp_carbon_nitrogen() uses for the residue that stays on the field (residue_c_kgdm, residue_n_kgdm, joined on item_prod_code), so the straw that goes through the yard and the straw that does not are described by one table.

The supply is aggregated over crops, because bedding is not traceable to the crop it came from once it is in the heap: the manure chain keys on year x territory (and sub_territory when the input carries one).

Usage

build_residue_bedding_supply(x)

Arguments

x

A tibble from calculate_residue_destinies() with item_prod_code, residue_bedding_dm_t, year and territory, and optionally sub_territory.

Value

A tibble with one row per year x territory (x sub_territory) and columns bedding_dm_t, bedding_c_t and bedding_n_t.

Examples

  year = 2020L, territory = "203", item_prod_code = "15",
  residue_bedding_dm_t = 1000
