Which of the following is the most common type of aeration used on sport turf?

1. Sand-based

2. Clay-based

3. Loamy

4. Silt-based

The correct answer is: Clay-based

The most common type of aeration used on sport turf is sand-based aeration. This method involves incorporating sand into the soil profile to improve drainage, reduce compaction, and enhance root growth. Sand-based aeration helps to create a more uniform playing surface, which is crucial for the performance of athletes and the overall health of the turf. Using sand allows for improved aeration and infiltration of water, which are essential for turf health, as it promotes deeper root systems and better resilience against wear. It helps distribute nutrients and moisture more evenly throughout the soil, thereby fostering a better environment for grass to thrive. In contrast, the other options—clay-based, loamy, and silt-based—do not provide the same level of drainage and compaction relief that sand offers, making them less advantageous for sport turf applications where performance and durability are priorities.
