Effects of burning harvested residues on the archaeal and bacterial communities of Eucalyptus urophylla substituting native vegetation

The land preparation method of burning harvested residues considerably affects soil archaeal and bacterial communities. However, the changes in the archaeal and bacterial communities of Eucalyptus urophylla plantation and the driving factors of microbial community diversity are still unknown. This study explored the effects of E. urophylla replacement for native vegetation and the burning of harvested residues on the diversity of archaeal and bacterial communities. Soil samples were collected from the E. urophylla plantation with burnt (Burn) and retained (Retain) harvest residues after 5 years, and the native vegetation was selected as a control (CK). Results show that significant differences in soil organic matter, available phosphorus, available boron, soil bulk density, and moisture content were found among the three stands (p
