Calculate Cropland NPP Components Including Weeds

Source: R/npp_functions.R
calculate_crop_npp_components.Rd

Calculates complete cropland NPP including weed biomass, scaled by potential NPP and considering fallow periods.

Usage

calculate_crop_npp_components(Crop_NPPpot, .by = NULL)

Arguments

Crop_NPPpot

A data frame with potential NPP values and crop data

.by

Character vector of column names for grouping operations (e.g., c("Year", "Region")). Used for scaling weeds calculations. If NULL, no grouping is applied.

Value

A data frame with complete cropland NPP components (crop + weeds) in DM, C, N

Examples

if (FALSE) { # \dontrun{
# With grouping by Year
cropland_npp <- calculate_crop_npp_components(crop_npp_potential, .by = "Year")

# With multiple grouping variables
cropland_npp <- calculate_crop_npp_components(crop_npp_potential, 
                                                .by = c("Year", "Region"))

# Without grouping
cropland_npp <- calculate_crop_npp_components(crop_npp_potential, .by = NULL)
} # }
