Benefits

 

As lawns age or sustain heavy use from play, sports activities, pets, vehicle traffic and parking, soil compaction 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. Core aeration can benefit your lawn by:

• Increasing the activity of soil microorganisms that decompose thatch.
• Increasing water, nutrient and oxygen movement into the soil.
• Improving rooting.
• Enhancing infiltration of rainfall or irrigation.
• Ability of water and fertilizer to penetrate to the grass roots soil's absorption rate from irrigation
• Grass's ability to withstand low water situations and heat stress
• Root growth activity contributing to the strength and health of the grass
• Ability of bacteria present in the soil to break down and decompose the thatch layer thus increasing the soils ability to hold sufficient amounts of moisture between waterings
