| Zusammenfassung |
| Weathering of biochar will lead to its eventual mineralisation to CO2, but how does this happen and how quickly will the biochar break down?
This study focuses on the fate of charcoal, as an analogue for biochar, over a ten year period in rural Ghana. The objectives of the work were to determine the stability of charcoal over this timeframe, the change in its functional properties and to calibrate or validate recently established approaches to age biochar artificially.
The study showed that the oxygen-to-carbon ratio of charcoal surfaces generally increases over time. Gradually the oxidation penetrates the subsurface layers, causing surface layers to erode and exposing previously un-aged surfaces to degradation. |
