Cation exchange capacity (CEC) is a routinely measured soil fertility indicator. The standard NH 4 OAc (pH 7) extraction procedure is time-consuming and overestimates actual CEC values of variable charge soils. Unbuffered extractants have been developed to measure the effective CEC (eCEC), but they differ in the type of index cation … free from 106\u0026park 2022
