Changes in soil total organic carbon of Aiyinase and Cape Coast soils following application of corncob biochar and/or compost 14 days after incubation. B0 = control with no amendments; B20 = biochar 2%, w/w; C20 = compost 2%, w/w; BC = combined biochar and compost rate 1% compost + 1% biochar. Error bars represent standard deviation of the means.
