Readily oxidizable organic carbon
Web1 day ago · The prospect of runaway greenhouse emissions emerging from the organic matter in thawing permafrost has long been among the more frightening climate change scenarios, stoking fears that warming ... WebSep 1, 2024 · The soil ROC was analyzed as described by Blair et al. (1995)and Chen et al. (2012), with 0.333 M KMnO4solution used as the oxidizer. The difference between the SOC and ROC of each sample presented the non-readily oxidizable organic C (NROC) content and the ratio of ROC to NROC indicated the lability of SOC (Blair et al., 1995; Chen et al., 2015).

WebSoil easily oxidizable organic carbon (EOC) is directly related to CO2 density, dynamics in subsurface EOC have been observed globally in relation to rapid urbanization. WebAbstract Soil organic carbon (SOC) of reclaimed minesoil (RMS) is regarded as an important part of terrestrial SOC, and SOC losses of RMSs occur during the substantial soil compaction and the removal, storage and backfilling of the topsoil, which lead to poor soil structure.
Content of the readily oxidizable organic carbon (ROC) was analyzed following the description of Chen et al. ( 2012b ). In brief, each sample that contained ~20 mg of SOC was weighed in a 100-mL centrifuge cube to be oxidized using the oxidizing agent of 333 mM of KMnO 4 solution.
