Bongdaesan (a: Unplanted area; b: Prunus yedoensis plantation; c: Quercus acutissima plantation; d: Pinus thunbergii plantation; e: Liriodendron tulipifera plantation; f: wood stakes after seven month’s incubation at top 15cm soil).
Fig. 2. Soil property changes (a: soil water content; b: soil temperature; c: soil pH; d: soil EC; e: organic carbon; f: total nitrogen; g: available phosphorus; h: soil CO2 efflux rates) following soil amendment treatments (C: Control, CLB: Compound fertilizers + Lime + Biochar, LB: Lime + Biochar) in a post-fire restoration area. Vertical bars represent one standard error. The same letters among treatments in each sampling time indicate no significant difference at P < 0.05.

Remaining weight (a), carbon (b) and nitrogen (c) concentration, C/N ratio (d), remaining carbon (e) and nitrogen (f) of wood stakes following soil amendment treatments (C: Control, CLB: Compound fertilizers + Lime + Biochar, LB: Lime + Biochar) in a post-fire restoration area. Vertical bars represent one standard error.
