This layer is the most efficient in the soil.
These aggregates tend to resist compaction and contribute greatly to permeability, favorable bulk density and porosity. The surface layer, rich in raw material, also is a warehouse of slow-release nutrients that are practical for plant growth. The underlying layers are not as efficient as the surface area layer due to lower organic matter content.
