Page last updated: Tuesday, 12 January 2021-3:06pm. Soil aggregate stability is the ability of a soil to regulate the movement and storage of air and water throughout the soil profile. The profile is determined by the mix of sand, silt and clay particles. The more stable the soil's aggregates, the more productive the soil.

· Greater soil aggregate stability was observed in mycorrhiza-inoculated replant soil than in non-mycorrhizal soil due to the increase of water-stable aggregates in 2–4 mm and 1–2 mm size. In addition, a total of 92 substances were identified in root exudates, and the mycorrhizosphere had considerably more root exudate compositions.

· Why it is important: Changes in aggregate stability may serve as early indicators of recovery or degradation of soils. Aggregate stability is an indicator of organic matter content, biological activity, and nutrient cycling in soil. Generally, the particles in small aggregates (< 0.25 mm) are bound by older and more stable forms of organic matter.
