Distribution characteristics of organic carbon (nitrogen) content, cation exchange capacity, and specific surface area in different soil particle sizes. [PDF]

open access: yesSci Rep, 2023
Understanding the distribution of soil organic carbon and nitrogen (OC(N)) content, cation exchange capacity (CEC), and specific surface area (SSA) in different soil particle sizes is crucial for studying soil fertility and properties.

Effective cation exchange capacity of calcium silicate hydrates (C-S-H)

open access: yesCement and Concrete Research, 2021
The binding of alkalis and calcium to calcium silicate hydrate (C-S-H) can be measured by cation exchange using cobalt hexamine solution with adapted pH. The effective cation exchange capacity (CEC) decreased at higher Ca/Si in C-S-H.

Mapping cation exchange capacity using a quasi-3d joint inversion of EM38 and EM31 data

open access: yesSoil and Tillage Research, 2020
Cation exchange capacity (CEC, cmol(+) kg−1) is a measure of the capacity of soil to retain and exchange cations. However, it is expensive to sample and directly measure across a heterogenous field and at different depths.

Cation exchange capacity of biochar: An urgent method modification [PDF]

open access: yesScience of The Total Environment, 2018
Biochar, produced through pyrolysis of organic matter, is negatively charged, thus contributing to electrostatic adsorption of cations. However, due to its porous structure and contents of alkaline ashes, the determination of the cation exchange capacity (CEC) is challenging.

Effective cation-exchange capacity in Finnish mineral soils

open access: yesAgricultural and Food Science, 1971
Effective CEC of 230 mineral soil samples was estimated as sum of (Ca + Mg) and (AI + H) displaced by N KCI. The mean values as me/100 g of soil were, in the surface samples, 15.9 ± 2.0 in 46 clay soils, 8.9 ± 1.3 in 21 silt and loam soils, and 8.3 ± 1.1

Enhancing Cation Exchange Capacity of Weathered Soils Using Biochar: Feedstock, Pyrolysis Conditions and Addition Rate

open access: yesAgronomy, 2020
The addition of alkaline and high-cation exchange capacity (CEC) biochars is a suitable strategy to increase the CEC of weathered soils. The aim of this study was to evaluate the effect of biochar from different feedstocks and pyrolysis temperatures on ...

A Critical Evaluation of the Relationship Between the Effective Cation Exchange Capacity and Soil Organic Carbon Content in Swiss Forest Soils

open access: yesFrontiers in Forests and Global Change, 2020
An improved identification of the environmental variables that can be used to predict the content of soil organic carbon (SOC) stored belowground is required to reduce uncertainties in estimating the response of the largest terrestrial carbon reservoir ...
