This function calculates the phosphate excess
Usage
osi_nut_p_dk(B_LU, A_P_OL, unitcheck = TRUE)
Arguments
- B_LU
(numeric) The crop code
- 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 excess index in Denmark derived from extractable soil P fractions. A numeric value.
Examples
osi_nut_p_dk(B_LU = '3301010399',A_P_OL = 5)
#> [1] 0.9378507
osi_nut_p_dk(B_LU = c('3301010399','3301029800'),A_P_OL = c(3.5,5.5))
