In aj-sykes92/soilc.ipcc: The IPCC (2019) Tier 2 Steady-State Method for Soil Carbon

Description

To be used as an argument to the build_soil_input() function. Creates an object containing crop management information and checks it for correct format and values. Arguments should be vectors of matching length, or of length 1.

Usage

add_crop(crop, yield_tha, frac_remove, frac_renew)

Arguments

crop	A character vector indicating the crop type. See names(crop_fractions) for possible options.
yield_tha	A numeric vector indicating crop yield in tonnes fresh weight ha^-1.
frac_remove	A numeric vector indicating the fraction of crop residues removed, values between 0 and 1.
frac_renew	A numeric vector indicating the fraction of the crop renewed annually, values between 0 and 1. Equal to 1 for annual crops, 1 / renewal period in years for perennial crops.

Examples

add_crop(crop = c("wheat", "barley"),
         yield_tha = c(7.5, 8.1),
         frac_remove = c(0.3, 0.4),
         frac_renew = c(1, 1))
