WebJun 1, 2009 · The cation exchange capacity (CEC) is one of the most important properties of clays in terms of their performance in both natural and technical processes. For decades, common methods for determining exchangeable cations have failed when calcareous clays or soils were examined, because calcite is at least partly dissolved throughout the … WebMay 2, 2024 · In standard method, CEC is obtained by ammonium acetate 1 N pH 7 method, while the distribution of soil pH in Indonesia is very diverse from pH 4 to pH 8. Also, there are differences in factors ... WebApr 10, 2024 · Background. 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 … pasta filled with potato
