However, the mechanisms controlling P\n                    <jats:sub>coll<\/jats:sub>\n                    dynamics across aggregate fractions, particularly macroaggregates (MAC, 2\u20130.25\u00a0mm) and microaggregates (MIC,\u00a0&lt;0.25\u00a0mm) remain poorly understood in Ultisols. This study systematically investigated P\n                    <jats:sub>coll<\/jats:sub>\n                    release via water\u2010dispersible colloids (C\n                    <jats:sub>rq<\/jats:sub>\n                    ), P\n                    <jats:sub>coll<\/jats:sub>\n                    content, colloidal surface morphology, and stability across varying slope positions, pedogenic horizons, and cultivation histories. Key findings reveal that C\n                    <jats:sub>rq<\/jats:sub>\n                    and P\n                    <jats:sub>coll<\/jats:sub>\n                    concentrations increased significantly with soil depth, by approximately 200%\u20131400% and 25%\u201367%, respectively, with MAC exhibiting consistently higher P\n                    <jats:sub>coll<\/jats:sub>\n                    retention than MIC. Scanning electron microscopy highlights distinct colloidal structures: MAC contain larger, loosely bound particles, whereas MIC display compact, layered arrangements.
