The addition of biochar significantly increased total PLFA-C abundance
(p b 0.05), especially at the early stage of the incubation (Table
S4, Fig. S3). The increased amount of PLFAs in the 300BC-amended soil
was observed to be significantly higher than that of 500BC and 700BC.
In accord with the other study using PCR-DGGE, significantly and greatly
increased bacterial gene abundance, as well as the small increase in
