The potential significance of stabilising plant-fixed carbon into charcoal-like material for climate change mitigation is now well established. However, the pattern of ageing in biochar and its quantitative degradation has only been possible using modelling techniques. The general objectives of this project are to assess the medium-term (decadal) stability of biochar using a chronosequence of sites where the used of biochar has been used for managing soil fertility for increasing lengths of time (a traditional practice in Ghanaian agriculture). This will be established by surface examination of biochar particles of different age, and triangulating with biochar samples artificially aged using the toolkit described above.
