Core Aeration

Core Aeration – “Breath Life into Your Roots”
 
The practice of physically removing cores of soil and leaving holes or cavities in the lawn is defined as core aeration or aerification. “See Core Aeration Illustration” Lawn owners often don’t realize that symptoms of soil compaction. Insects, disease, nematodes, improper watering and a lack of fertilizer are often blamed for a lawn’s decline, when the real culprit is soil compaction. The problem starts when particles in the top 4 inches of the soil are compressed, reducing the pore spaces between them an impeding the movement of air, water, and nutrients to the grass roots. This, in turn stresses the grass plants, making them less able to compete with weeds and slow to recuperate from injury. In time, a compacted lawn needs renovation.

Compacted soil contributes to the accumulation of thatch because restricted oxygen levels in highly compacted soils or finely textured soils, particularly heavy clays, impairs the activity of earthworms and other thatch decomposing organisms. Left unmanaged, thatch can lead to serious maintenance and pest problems. Thatch accumulate faster on compacted soils, heavy clay soils and subsoils that are disturbed during building processes than on well-aerified soils. Therefore, some lawns may require frequent aerification (at least one time per year) to aid in thatch control. If the soil is compacted, the solution is straight forward: AERIFY.
