How To Aerate A Lawn

This traffic includes human activity, pet runs, or vehicular movement. Soils can also become compacted during residential or commercial construction processes due to the movement of heavy equipment on the lawn. Another source of compaction is heavy precipitation events. Soil compaction is a major contributing factor overseeding lawn in turfgrass decline. In Missouri, it is not uncommon for cool-season lawns to look less than perfect after the stress of a hot summer. Disease, drought, heat, or poor soil may mean that it’s time for a round of overseeding. To keep a lawn looking great it will probably need at least some overseeding each year.

Restricted oxygen levels in highly compacted soils, due to the compaction itself or from poor drainage, impair the activity of earthworms and other thatch-decomposing organisms. Left unmanaged, thatch can lead to serious maintenance and pest problems. Thatch accumulates faster on compacted soils and heavy clay soils than on well-aerified soils. Therefore, alleviating soil compaction in lawns will aid in thatch control. Homeowners often overlook problems associated with soil compaction. Soil compaction can severely restrict turfgrass growth and can arise in lawns from a variety of events. Traffic over a lawn or specific areas of a lawn is probably the leading factor in soil compaction.
