This function calculates the phosphate availability.
Usage
osi_c_phosphor_it(B_LU, A_P_OL, B_TEXTURE_HYPRES, unitcheck = TRUE)
Arguments
- B_LU
(numeric) The crop code
- A_P_OL
(numeric) The P-content of the soil extracted with Olsen (mg/kg)
- B_TEXTURE_HYPRES
(character) The soil texture according to HYPRES classification system
- unitcheck
(character) Option to switch off unit checks (TRUE or FALSE)
Value
The phosphate availability index in Italy derived from extractable soil P fractions. A numeric value.
Examples
osi_c_phosphor_it(B_LU = '3301061299',A_P_OL = 5,B_TEXTURE_HYPRES ='C')
#> [1] 0.4449934
osi_c_phosphor_it(B_LU = c('3301061299','3301000000'),
A_P_OL = c(3.5,5.5),B_TEXTURE_HYPRES =c('C','C'))
#> [1] 0.2799838 0.4994822
