Aggregate Stability - an overview ScienceDirect Topics
Aggregate stability decreases, often linearly, with increasing water content at freezing. This relationship appears to hold for many soils ranging in texture from sandy loams to silty clays. As soil water contents increase, more water is available to form ice crystals or ice lenses.

Aggregate stability and assessment of soil
Aggregate stability and assessment of soil crustability and erodibility : I . Theory and methodology Y. Crusting and erosion of cultivated soils result from aggregate breakdown and the detachment of soil fragments by rain, and the susceptibility of soil to these processes is often inferred from measurements of aggregate stability.

Aggregate stability and assessment of soil crustability and
A unified framework for the measurement of aggregate stability is proposed to assess a soil's susceptibility to crusting and erosion. It combines three treatments having various wetting conditions and energies (fast wetting, slow wetting, and stirring after pre-wetting) and measures the resulting fragment size distribution after each treatment.

How is soil aggregate stability tested? ATTRA
The oldest and most commonly used method for testing aggregate stability involves placing a soil sample on a nest of soil sieves with screen sizes typically ranging from 1 mm to 45 microns and then moving this nest of sieves up and down in a bucket of water. The more stable aggregates will stay on the top sieve, while less stable aggregates ...
