Changes in exchangeable cations and exchange capacity of soil consequent on oxidation of its organic matter
Published online by Cambridge University Press: 27 March 2009
Extract
1. Loss of ignition at 450°C. and the organic carbon content of some shale soils are positively correlated (r = +0·99).
2. Base exchange capacities and exchangeable cations were determined on soils, treated and untreated with hydrogen peroxide solution.
3. Oxidizing the organic matter lessened the exchange capacities of all samples; the exchange capacity of the organic matter varied from 67·5 to 97·0 m-equiv./1OO g. dry material.
