Turf Management & Sports Field Maintenance Flashcards

What is the optimal soil pH range for most cool-season turfgrass species?

Answer: 6.0–7.0

Most turfgrass species perform best at a soil pH of 6.0–7.0, which optimizes nutrient availability and microbial activity.

Which warm-season turfgrass is most commonly used for sports fields in the southern United States?

Answer: Bermudagrass

Bermudagrass is the most widely used warm-season turfgrass for sports fields in the South due to its durability, heat tolerance, and rapid recovery from wear.

What is 'thatch' in turfgrass management?

Answer: A layer of dead and living organic matter between the soil and grass blades

Thatch is the layer of living and dead organic matter (stems, roots, rhizomes) that accumulates between the soil surface and the green grass blades.

What is the primary purpose of core aerification in sports turf management?

Answer: To relieve soil compaction and improve air, water, and nutrient movement

Core aerification relieves soil compaction by removing soil cores, which improves the movement of air, water, and nutrients to the root zone.

Which macronutrient is primarily responsible for turfgrass color and shoot growth?

Answer: Nitrogen (N)

Nitrogen is the primary macronutrient responsible for shoot growth and the green color of turfgrass, as it is a key component of chlorophyll.

What is the typical mowing height range for bermudagrass maintained on a high-traffic sports field?

Answer: 0.5–1.5 inches

Bermudagrass sports fields are maintained at 0.5–1.5 inches to provide a firm, smooth playing surface and encourage dense lateral growth.

What does 'topdressing' refer to in turf management?

Answer: Applying a thin layer of sand or soil mixture to the turf surface

Topdressing involves applying a thin layer of sand, compost, or soil mixture to the turf surface to smooth the surface, dilute thatch, and improve soil structure.
