What does core aerification involve?

• A. Adding organic matter to the soil
• B. Pulling soil cores with a machine on a pattern of 6" apart
• C. Mixing sand into the soil
• D. Applying fertilizers over the lawn

Answer: (B)

Core aerification involves the process of pulling soil cores from the ground, which is done using a specialized machine designed for this purpose. This technique creates holes in the soil, usually spaced about 6 inches apart, which improves air circulation, enhances root development, and allows for better water infiltration and nutrient absorption. By removing these soil cores, the compacted soil is loosened, creating space for oxygen, moisture, and beneficial microorganisms to thrive, ultimately leading to a healthier lawn. In contrast, the other options pertain to different practices in soil management or lawn care. For instance, adding organic matter to the soil improves its structure and fertility but does not involve the physical removal of soil cores. Mixing sand into the soil is a method often used to improve drainage but again does not represent core aerification. Applying fertilizers might enhance plant nutrition but does not address soil compaction or aeration, which are the primary concerns that core aerification targets.
