Calculate the phosphate availability (PBI)
Description
This function calculates the phosphate availability. This value can be evaluated by ind_phosphate_availability
Usage
calc_phosphate_availability(
B_LU_BRP,
A_P_AL = NULL,
A_P_CC = NULL,
A_P_WA = NULL
)
Arguments
B_LU_BRP |
(numeric) The crop code from the BRP |
A_P_AL |
(numeric) The P-AL content of the soil |
A_P_CC |
(numeric) The P-CaCl2 content of the soil |
A_P_WA |
(numeric) The P-content of the soil extracted with water |
Value
The phosphate availability index estimated from extractable soil P fractions. A numeric value.
Examples
calc_phosphate_availability(B_LU_BRP = 265, A_P_AL = 45, A_P_CC = 2.5)
calc_phosphate_availability(c(265,1019),A_P_AL = c(35,54),A_P_CC = c(2.5,4.5), A_P_WA = c(35,65))
