This function estimate how much cations can be buffer by soil, being calculated by calc_cec
ind_cec(D_CEC)
(numeric) The value of CEC calculated by calc_cec
The evaluated score for the soil function to buffer cations. A numeric value between 0 and 1.
ind_cec(D_CEC = 85)
#> [1] 0.85
ind_cec(D_CEC = c(85,135,385))
#> [1] 0.85 1.00 1.00
