Supplementary file 1_Combined application of organic and microbial amendments reshapes soil microbiome diversity and improves soybean growth performance.pdf

Notably, the Proteobacteria, including the rhizobial genus Ensifer, was significantly enriched in the rhizosphere upon MM treatment, while the relative abundance of Ascomycota was increased in both bulk and rhizospheric soil upon MA treatment. To co-relate with these soil microbiome features, the MM treatment was shown to have the most significant effect on the soybean growth promotion, including the notably higher aboveground and underground fresh weight, plant height, accompanied with markedly more root nodules, than either MI or MA treatment.

Collectively, our results suggest that the combined application of organic and microbial amendments effectively reshapes the soil microbiome by enhancing microbial diversity and enriching nitrogen-fixing bacteria in the rhizosphere, thereby promoting the nitrogen-fixing potential and productivity of soybean.</p>
