Core aeration pulls soil plugs from your lawn to aerate and allow thatch, sand, and air to enter. Soil also relieves compaction. It has many benefits, such as:
- Reduces compaction
- Reduces thatch in the lawn
- Stimulates root growth
- Great bed for overseeding, giving you great seed to soil contact
- Increases the flow of nutrients such as oxygen, water, and fertilizer
"Compaction" is a term applied to soil which, deprived of proper aeration, suffers from excessive water runoff and poor conditions for plant rooting. Soil compaction can be corrected mechanically through core aeration; in nature, earthworms do a good job of working against soil compaction. In reference to compost bins, compaction occurs under anaerobic conditions. Turning a compost pile frequently is one way to avoid such compaction.
