Long-term application of biogas slurry altered the microbial community structure and metabolites in rhizosphere soil of poplar plantations

We aim to investigate the changes in the structure and function of rhizosphere microorganisms when different concentrations of biogas slurry are applied to the rhizosphere of poplar trees. By measuring the variations and types of rhizosphere metabolites, we can determine the microbial changes and their impact on the rhizosphere microenvironment of poplar trees.
