Soil colloidal phosphorus (CP) is an active component that cannot be overlooked in the soil phosphorus cycle. Its occurrence forms and migration behavior significantly influence phosphorus bioavailability and environmental risks. This paper systematically reviews the multiscale regulatory mechanisms of microbial actions in CP transformation and migration. It focuses on chemical effects (e.g., proton secretion, iron reduction, and organic acid coordination), physical effects (e.g., extracellular polymer trapping and biofilm pore remodeling), and microbial community dynamics and molecular ecology three dimensions to elucidate how microbes drive CP activation, immobilization, and migration through interfacial reactions, functional gene expression, and community interactions. The paper further explores the synergistic effects of multiple factors on microbial regulation processes, including soil physicochemical properties, agricultural management practices, and emerging pollutants. It identifies current research gaps in cross-scale coupling, in situ characterization, and mechanism modeling, while providing theoretical foundations and research directions for enhancing soil phosphorus utilization and pollution control.
