Summary

Abstract Soil aggregate stability is critical for maintaining soil fertility and mitigating environmental issues like erosion, yet the mechanisms by which interparticle interactions (van der Waals attraction, and electrostatic and hydration repulsion) govern stability across aggregate sizes remain unclear. This study investigated the distribution characteristics, influencing factors, and mechanisms of interparticle forces affecting aggregate structure stability for different‐sized aggregates (2–5, 1–2, 0.25–1, 0.053–0.25 mm) using the pipette method and soil electrochemical theory. Results revealed that aggregate stability decreases significantly as electrolyte concentration decreases, with larger aggregates exhibiting stronger stability due to net attractive forces dominating interparticl
