The soil with the greatest cec is
WebThe cation exchange capacity (CEC) measures the soil’s ability to temporarily hold on to different cations and many nutrients in the soil are cations. Soil in the Northern Great Plains has a net negative charge and can hold onto positively charged ions such as calcium (Ca ++), magnesium (Mg ++), zinc (Zn ++), potassium (K +) and ammonium (NH ... 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 cation …
