This function calculates the precipitation surplus (in mm / ha) given the crop rotation plan.
calc_psp(B_LU_BRP, M_GREEN)
Arguments
- B_LU_BRP
(numeric) The crop code from the BRP
- M_GREEN
(boolean) A soil measure. Are catch crops sown after main crop (optional, options: TRUE, FALSE)
Value
The estimated precipitation surplus (in mm / ha) depending on averaged precipitation and evaporation. A numeric value.
Examples
calc_psp(B_LU_BRP = 265, M_GREEN = TRUE)
#> [1] 220.993
calc_psp(B_LU_BRP = c(265,1019,265,1019), M_GREEN = rep(TRUE,4))
#> [1] 220.993 311.568 239.698 311.568
