Calculate the precipitation surplus

Source: R/bln_calc_psp.R
bln_calc_psp.Rd

This function calculates the precipitation surplus (in mm / ha) given the crop rotation plan. Is identical to OBIC function calc_psp but much faster to facilitate national and regional calculations

Usage

bln_calc_psp(ID, B_LU_BRP, M_GREEN)

Arguments

ID

(character) A field id

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

bln_calc_psp(ID = 1,B_LU_BRP = 265, M_GREEN = TRUE)
#> [1] 228.18
bln_calc_psp(ID = c(1,2,1,2),B_LU_BRP = c(265,1019,265,1019), M_GREEN = rep(TRUE,4))
#> [1] 239.698 311.568 239.698 299.910
