Soil Aggregate Stability a soil health physical

A suite of soil health measurements are becoming available which are not part of the traditional soil chemical tests. Soil aggregate stability is an important physical indicator of soil health, which protects organic matter accumulation, improves soil porosity, drainage and water availability for plants, decreases soil compaction, supports biological activity, and nutrient cycling in the soil.

Soil aggregate stability Wikipedia

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 (Papadopoulos, 2011; USDA, 2008).Soil aggregate stability is a measure of soil structure (Six et al., 2000a) and can be impacted by soil management (Six et al., 1998
