In mined land rehabilitation, the topsoil plays a very important role not only as a growth medium for plants but also a bank for indigenous plant seeds. However, because most topsoils are stockpiled for longer periods during mineral exploitation, their physical, chemical and biological properties may be altered by the time of rehabilitation. This results in soil nutrient depletion, soil degradation and lack of topsoil which are issue of great concern for most mining companies during disturbed mine site reclamation. It is therefore important to amend disturbed minesoils to provide alternatives topsoil substitute for successful mine rehabilitation. In the light of the recent global concern for biodiversity loss and climate change, most human efforts have been aligned towards climate change mitigation and biodiversity enhancement including rehabilitation of degraded lands. Biochar has proven to be of great potential in disturbed soil amendment and climate change mitigation since apart from restoring soil nutrients, biological properties, stability and reducing heavy metal concentration also returns large amounts of carbon in plant biomass to the soil. This study therefore seeks to explore the potential of biochar produced from Bambusa vulgaris (a readily available local resource in the study area) for soil amendment and floristic diversity promotion at the Yongwa quarry site.
