Soil compaction has a negative effect on all turf functions. Lack of oxygen is the single greatest negative result of compaction. Core aeration (use of open tines that pull a plug) is very effective at getting oxygen into the soil profile and actually improves soil structure. All turf areas will be aerated in early fall (all irrigation heads will be marked prior to aeration).
