Benefits of Core Aeration
1. Stress recovery and prevention
• Aeration will help lawns recover from the stress of drought, foot traffic, disease, and insect damage naturally.
• Seeding is recommended at the time of aeration to introduce new plant varieties that will rejuvenate your lawn.
• Increases the lawn's drought tolerance and improves its overall health.
2. Reduce soil compaction
• Soil plugs break down and filter back into the lawn to help loosen the soil.
3. Increased air and moisture movement in the soil
• Loosened soil provides an excellent medium for new root development.
• Reduces water runoff.
• Enhances oxygen levels in the soil, stimulating root growth and enhancing the activity of thatch-decomposing organisms.
4. Overall reduction in thatch
• Soil pugs deposited on top of the lawn aids in microbial decomposition of thatch.
• A controlled thatch layer will prevent possible disease problems.
Core aeration can be used to minimize thatch accumulation, to modify its physical characteristics, and to reduce soil compaction. Soil plugs are deposited on the turf surface. These plugs then break down and redistribute soil throughout the thatch layer. The soil from the plugs helps to modify the physical structure of the thatch, making it a better growing medium.
This soil also enhances thatch breakdown by introducing the beneficial microorganisms that feed on thatch.
Most turf grasses growing in heavy clay or poor soils benefit greatly from annual aeration to reduce thatch buildup and more importantly, to relieve soil compaction. This cultural treatment will help improve the recycling flow of air, water, and fertilizer to your grass plants. This, in turn, will help to rejuvenate your grass by allowing the roots to grow deeper, creating healthier grass plants and keeping your lawn thicker and greener.
The building process has seriously disturbed most home lawns, the natural soil. Fertile topsoil may have been removed or buried during excavation of the basement or footings, leaving subsoil that is more compact, higher in clay content and less desirable for healthy lawn growth. These lawns need aeration to improve the depth and extent of turfgrass rooting and to improve fertilizer and water use.
