This function calculates the phosphate availability.
Usage
osi_c_phosphor_es(B_LU, A_CLAY_MI, A_SAND_MI, A_P_OL, unitcheck = TRUE)
Arguments
- B_LU
(numeric) The crop code
- A_CLAY_MI
(numeric) The clay content of the soil (%)
- A_SAND_MI
(numeric) The sand content of the soil (%)
- A_P_OL
(numeric) The P-content of the soil extracted with Olsen (mg/kg)
- unitcheck
(character) Option to switch off unit checks (TRUE or FALSE)
Value
The phosphate availability index in Spain derived from extractable soil P fractions. A numeric value.
Examples
