The mechanism of biochar and compost as soil amendments in urban green spaces remains unclear. Using Euonymus kiautschovicus as a model system, this study established eight treatment gradients, 0 (CK), single biochar applications: 4% (BC4), 8% (BC8), 12% (BC12), 7.5% compost (COM), and their combinations BCC4 (BC4 + 7.5% COM), BCC8 (BC8 + 7.5% COM), BCC12 (BC12 + 7.5% COM). Through metagenomic sequencing and metagenome-assembled genomes (MAGs) analysis, the authors investigated soil microbiome structure, carbon sequestration functional genes, and their interactions in response to amendments.
