This function calculates the potassium excess.
Usage
osi_nut_k_ie(B_LU, A_SOM_LOI, A_K_NaAAA)
Arguments
- B_LU
(numeric) The crop code
- A_SOM_LOI
(numeric) The percentage organic matter in the soil (%)
- A_K_NaAAA
(numeric) The K-content of the soil extracted with Morgan's solution, sodium acetate acetic acid (mg/ kg)
Value
The potassium excess index in Ireland derived from extractable soil K fractions. A numeric value.
Examples
osi_nut_k_ie(B_LU = 265,A_SOM_LOI = 2,A_K_NaAAA = 5)
#> [1] 0.9728091
osi_nut_k_ie(B_LU = c(265,1019),A_SOM_LOI = c(2,4),A_K_NaAAA = c(3.5,5.5))
#> [1] 0.9734198 0.9727546
