This function calculates the phosphate availability.
Usage
osi_c_phosphor_nl(
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 (mg P/ kg)
- A_P_CC
(numeric) The P-content of the soil extracted with CaCl2 (mg P/ kg)
- A_P_WA
(numeric) The P-content of the soil extracted with water (mg P/ kg)
Value
The phosphate availability index in the Netherlands estimated from extractable soil P fractions. A numeric value.
Examples
osi_c_phosphor_nl(B_LU = 265, A_P_AL = 45, A_P_CC = 2.5)
#> [1] 0.9404573
