Question 1
, Page 2 of 115
A turf manager notices thinning grass in shaded areas under trees despite proper fertilization and
irrigation. What is the most likely cause?
A. Excess nitrogen application
B. Insufficient sunlight limiting photosynthesis
C. Overwatering
D. Soil pH imbalance
Answer: B
Rationale: Shade reduces light availability, limiting photosynthesis and turf growth.
Question 2
A soil test reveals low phosphorus levels in a turf area. Which function is phosphorus most critical for in
turfgrass?
A. Leaf color development
B. Root development and energy transfer
C. Water uptake
D. Pest resistance
, Page 3 of 115
Answer: B
Rationale: Phosphorus supports root growth and energy transfer (ATP).
Question 3
A superintendent applies fertilizer before a heavy rainstorm. What is the primary risk associated with
this timing?
A. Improved nutrient uptake
B. Nutrient runoff into waterways
C. Increased root growth
D. Reduced fertilizer cost
Answer: B
Rationale: Rain can wash away nutrients, causing environmental contamination.
Question 4
A turf area shows poor drainage and water pooling after irrigation. What is the most likely soil issue?
, Page 4 of 115
A. Sandy soil
B. Compacted soil reducing infiltration
C. Excess organic matter only
D. High potassium levels
Answer: B
Rationale: Compaction limits water movement through soil.
Question 5
Which mowing practice is most appropriate for maintaining healthy turf under stress conditions?
A. Removing more than one-third of leaf blade
B. Frequent mowing removing only one-third of leaf height
C. Mowing only once per month
D. Cutting very short regardless of species
Answer: B
Rationale: The one-third rule prevents excessive stress on turf.
