Heavy clay soils or soils with heavy foot or equipment traffic often
become compacted over time. Soil particles are pressed close together,
restricting the movement of oxygen, nutrients, and water to the lawn.
As a result, the turfgrass grows slowly and poorly. Turfgrass grown in
compacted soils soon become susceptible to drought, disease, and insect
to alleviate soil compaction
Aerating the soil removes small cores of soil from the lawn, allowing
air, water, and nutrients to penetrate the soil.
