Peat soil formation
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 … Webin peat-forming systems is widely recognized and has been extensively studied. Early work described the role of mangroves in soil accretion and noted the contribution of mangrove roots to peat formation (e.g. Bird, 1971; Woodroffe, 1983; Parkinson et al., 1994; Cahoon & Lynch, 1997; McKee & Faulkner, 2000a).
