Values are in nmols PLFA g-1 soil. Treatments include unamended control (CK), 12.5 t ha-1 biochar (B1), 25 t ha-1 biochar (B2), 5 centimeter (cm) green waste compost (CM), and 12.5 t ha-1 biochar and 5 cm compost (B1+CM). Different letters indicate values that are significantly different across treatments (Holm-Šídák, P ≤ 0.05).
