Soil structure must be maintained to allow the functioning of the dynamic processes (e.g., aeration, water transmission and retention, root growth). Different manifestations of soil structure include aggregation and its stability; porosity and pore-size distribution, especially macropores; water retention and transmission properties; and compatibility. Once destroyed, these favorable attributes of soil structure are difficult to restore.
