Threshold effects of organic amendment on acidic red soil remediation: Community assembly and core microbiome-mediated metabolic coupling.
To identify the ecological threshold and microbial mechanisms underlying organic amendment (OA)-mediated remediation of acidic red soils, pak choi was employed as a model plant, and a gradient of digestate-derived OA from 0% to 25% was established. This study integrated soil-plant assessment, community assembly modelin...
