Aeration/Thatch removal

 

 

As lawns age or sustain heavy use from play, sports activities, pets, vehicle traffic and parking, soil compaction and thatching can result. Soil compacting forces are most severe in poorly drained or wet sites. Compaction greatly reduces the pore space within the soil that would normally hold air. Roots require oxygen to grow and absorb nutrients and water. Compaction reduces total pore space and the amount of air within the soil. It has a negative impact on nutrient uptake and water infiltration, in addition to being a physical barrier to root growth. This results in poor top growth and lawn deterioration.

 

Thatch is a spongy layer of organic substance made up of leaves, grass roots and stems, rhizomes, and other similar materials, that builds up in your lawn.  Excessive thatch accumulation has lead to lawn rooting into thatch rather than soil.  Thatch will block water and nutrients from reaching your grass's roots, weakening the whole plant. Thatch can also trap moisture near the blades of your grass, increasing the likelihood of lawn disease.

Before aeration, water either runs off without supplying root and soil with vital air and nutrients or pools on level areas. Thatch build-up creates a barrier where water and air cannot penetrate. Root system weakens from lack of water, nutrients, and air making them vulnerable to disease and stress. 

After aeration, the combination of increases air and water quickly breaks up thatch between holes by increasing the activity of soil microorganisms. Air, water, and nutrients easily reach root systems, greatly enlarging and strengthening them. Aeration is the #1 recommended service for improving turf color, consistency, and improving stress tolerances.
