Solution(By Examveda Team)

Soil aggregate stability is a measure of the ability of soil aggregates to resist degradation when exposed to external forces such as water erosion and wind erosion, shrinking and swelling processes and tillage.

Calcium ions associated with clay generally promote aggregation also soils with over five percent of iron oxides, tend to have higher aggregate stability.
