A healthy soil associated with sustainable crop production is likely to be considered a sustainable agricultural system. Soil health indicators only have value if they influence management decisions that support soil and food security. The surface layer (<5 cm) of a field is disproportionally affected by arable land management practices. For silty-clay soils, structural degradation of this layer leads to slaking under the impact of rain, with implications for nutrient leaching, capping, crop emergence, infiltration, runoff and erosion. Thus, aggregate stability (rapid wetting) measurements have relevance for both soil and food security. Also, earthworm activity is a major factor regulating aggregate stability, and important for both soil functions and supporting plant productivity.
