Phosphorus fertilization and maize intercropping with peanut synergistically reshape rhizosphere microbiome and enhance crop yield

Our findings demonstrate that the synergy between P fertilization and intercropping enhances crop productivity through a microbiome-mediated mechanism. This synergy restructures the rhizosphere community into a functionally beneficial state, fostering a self-reinforcing plant-microbe-soil feedback loop. This study provides a mechanistic framework for developing integrated, microbiome-informed management strategies to support sustainable agricultural intensification.
