This function calculates the phosphate availability.
Usage
bln_c_posphor(B_LU, A_P_AL = NA_real_, A_P_CC = NA_real_, A_P_WA = NA_real_)
Arguments
- B_LU
(numeric) The crop code
- A_P_AL
(numeric) The P-content of the soil extracted with ammonium lactate
- A_P_CC
(numeric) The P-content of the soil extracted with CaCl2
- A_P_WA
(numeric) The P-content of the soil extracted with water
Value
The phosphate availability index in the Netherlands estimated from extractable soil P fractions. A numeric value.
Examples
bln_c_posphor(B_LU = 265, A_P_AL = 45, A_P_CC = 2.5)
#> [1] 0.9069136
bln_c_posphor(B_LU = c(265,1019),A_P_AL = c(35,54),A_P_CC = c(2.5,4.5), A_P_WA = c(35,65))
#> [1] 0.9180670 0.9966953
