Which term best describes the action of spreading sand on a field to improve its quality?

The term that best describes the action of spreading sand on a field to improve its quality is topdressing. Topdressing involves the application of a thin layer of material, such as sand, soil, or compost, over the surface of a playing field. This practice is primarily used to enhance the soil structure, promote healthy grass growth, and improve drainage. By adding sand, it can help alleviate compaction issues and improve aeration, which is essential for root development and overall turf health.

Compaction refers to the process of soil being compressed, typically due to foot traffic or equipment, which can hinder plant growth. While compaction may necessitate topdressing as a remedy, it does not represent the act of applying materials to the surface itself. Fertilization involves adding nutrients to the soil to foster plant growth, but it does not specifically relate to the practice of applying sand. Seeding involves planting new grass seeds and is a different process focused on establishing new turf rather than enhancing existing soil quality. Therefore, the action of spreading sand to improve field quality is aptly described by the term topdressing.
