Abstract The priming effect (PE) induced by biochar provides a basis for
evaluating its carbon (C) sequestration potential in soils. A 60 days’ laboratory
incubation was conducted, which involved the amendment of biochar (1% of soil
mass) produced from rice straw at 300ºC (B300) and 500ºC (B500) to young (Y)
and old (O) poplar plantation soils, with the aim of studying the responses of
biochar-induced PEs to poplar plantation ages. This incubation included six
treatments: Y + CK (control), Y + B300, Y + B500, O + CK, O + B300, and O +
B500. Carbon… More >
