This function calculates the phosphate excess.
Usage
osi_nut_p_es(B_LU, A_CLAY_MI, A_SAND_MI, A_P_OL)
Arguments
- B_LU
(numeric) The crop code
- A_CLAY_MI
(numeric) The clay content of the soil (%)
- A_SAND_MI
(numeric) The sand content of the soil (%)
- A_P_OL
(numeric) The P-content of the soil extracted with Olsen (mg/kg)
Value
The phosphate excess index in Spain derived from extractable soil P fractions. A numeric value.
Examples
osi_nut_p_es(B_LU = 265,A_CLAY_MI = 5,A_SAND_MI = 25, A_P_OL = 5)
#> [1] 0.9639066
osi_nut_p_es(B_LU = c(265,1019),A_CLAY_MI = c(5,10),
A_SAND_MI = c(25,15),A_P_OL = c(3.5,5.5))
#> [1] 0.9674534 0.9626447
