What is the primary benefit of core aeration?

• A. Improves soil compaction and root growth.
• B. Increases drought tolerance.
• C. Improves foliar color.
• D. Reduces thatch formation.

Answer: (A)

Relieving soil compaction to boost root growth is the main idea behind core aeration. By removing plugs, aeration loosens the soil and creates space for air, water, and roots to move more freely. That means roots can penetrate deeper, access moisture more effectively, and establish a stronger, more resilient root system. With a healthier root zone, the turf responds better to stress and traffic. Other effects like some improvement in drought tolerance can follow from a stronger root system, and aeration can help with thatch breakdown, but these are secondary to the primary benefit of reducing compaction and promoting root growth. Foliar color isn’t directly affected by aeration.
