1 Intercropping soybean green manure (SGM) enhanced soil pH, organic matter content, and available nitrogen, available phosphorus, and available potassium concentrations.2 Intercropping SGM altered soil microbial community composition and diversity, reconstructed co-occurrence networks, and enriched beneficial microbial taxa including Actinobacteria, Proteobacteria, Ascomycota, and Mortierellales.3 Intercropping SGM improved citrus fruit quality, significantly increasing total soluble solids content (TSS) and TSS/titratable acidity ratio (TSS/TA).4 Citrus fruit quality exhibited strong correlations with intercropping duration (years), soil physicoproperties, and soil microbial community characteristics (diversity and specific microbial taxa).5 Intercropping SGM in orchards critically enhanced soil quality and crop productivity, advancing sustainable agricultural practices.
