This function calculates the potassium availability.
Usage
osi_c_potassium_no(B_LU, A_K_AL, A_CLAY_MI)
Arguments
- B_LU
(numeric) The crop code
- A_K_AL
(numeric) The K-content of the soil extracted with ammonium lactate (mg K / kg)
- A_CLAY_MI
(numeric) The clay content of the soil (%)
Value
The potassium availability index in Norway derived from extractable soil K fractions. A numeric value.
Examples
osi_c_potassium_no(B_LU = 265,A_K_AL = 5,A_CLAY_MI=5)
#> [1] 1.39261e-15
osi_c_potassium_no(B_LU = c(265,1019),A_K_AL = c(3.5,5.5),A_CLAY_MI=c(3,5))
#> [1] 1.527040e-16 2.845062e-15
