Which soil structure benefits most from earthworm bioturbation?

💡 Explanation

Compacted clay benefits from bioturbation because it generates soil macropores that increase aeration and water infiltration via soil organism activity, therefore improving drainage. This helps more than sandy soil, rather than rapid leaching alone.
