Arguments
- A_K_AAA
(numeric) The exchangeable K-content of the soil measured via acid ammonium acetate extraction (mg K/ kg)
- A_CLAY_MI
(numeric) The clay content of the soil (%)
- B_LU
(character) The crop code
- unitcheck
(character) Option to switch off unit checks (TRUE or FALSE)
Value
The potassium availability index in Switzerland estimated from extractable potassium. A numeric value.
Examples
