Long-term biogas slurry fertilization alters rhizosphere soil metabolite profiles and microbial communities in poplar plantations.

ABSTRACT: Biogas slurry, a nutrient-rich organic fertilizer, has unclear impacts on plant-soil interactions. Rhizosphere metabolites serve as a bridge between plants and soil microorganisms, significantly influencing soil health and microbial activity. This study employed high-throughput sequencing and untargeted metabolomics to investigate microbial community and metabolite profiles in rhizosphere soil of poplar plantations treated with biogas slurry at different concentrations (Con: untreated; Low: 250 m³ ha^-1 yr^-1; High: 375 m³ ha^-1 yr^-1). Results showed that long-term application of biogas slurry significantly increased soil total nitrogen (TN) and available phosphorus (AP) levels, thereby enhancing soil fertility. Compared to fun
