EXAM 2026 |ALL QUESTIONS AND
CORRECT DETAILED ANSWERS
|ALREADY A GRADED |NEW AND
REVISED
Select the best answer for each question.
Answers are indicated in bold.
Rationales follow each question in italics.
1. Which of the following is the most common cool-season turfgrass
used in temperate climates?
A. Bermuda grass
B. Zoysia grass
C. Kentucky bluegrass
D. St. Augustine grass
Cool-season turfgrasses thrive in temperate regions; Kentucky
bluegrass is widely used for its adaptability and density.
2. Soil compaction primarily affects turfgrass growth by:
A. Increasing nutrient availability
B. Reducing air and water infiltration
C. Enhancing microbial activity
D. Promoting deep root growth
Compacted soil limits pore space, restricting oxygen and water
movement, which stresses turfgrass roots.
3. A turf manager notices yellowing of grass primarily in low spots
that retain water. Which condition is most likely?
A. Drought stress
B. Poor drainage and anaerobic soil
C. Excessive fertilization
D. High sunlight exposure
,2|Page
Waterlogged areas create anaerobic conditions that limit root
function and nutrient uptake, causing yellowing.
4. Which irrigation schedule is most effective for promoting deep
root development in turf?
A. Frequent shallow watering
B. Infrequent deep watering
C. Watering only during rainfall
D. Continuous misting
Deep, infrequent irrigation encourages roots to grow downward,
improving drought tolerance.
5. The primary purpose of aeration in turf management is to:
A. Fertilize the soil
B. Relieve compaction and improve root growth
C. Reduce weed competition
D. Increase mowing frequency
Core aeration creates holes in compacted soil, enhancing oxygen,
water, and nutrient movement to roots.
6. Which nutrient is most often deficient in sandy soils affecting
turfgrass growth?
A. Nitrogen
B. Phosphorus
C. Potassium
D. Calcium
Sandy soils leach potassium easily, making it a common limiting
nutrient.
7. A new turfgrass is planted using sod. How long before it can
typically withstand regular foot traffic?
A. Immediately after installation
B. 1–2 days
C. 1–2 weeks
D. 3–4 weeks
Sod needs time to establish roots in the underlying soil before
supporting traffic.
8. Which turfgrass maintenance practice is most effective in reducing
fungal disease pressure?
,3|Page
A. Watering at night
B. Mowing infrequently
C. Proper mowing height and adequate air circulation
D. Applying high nitrogen weekly
Correct mowing and airflow reduce leaf wetness and stress,
limiting fungal infections.
9. Which factor is most important when selecting turfgrass for a
shaded area?
A. High nitrogen requirement
B. Drought tolerance
C. Shade tolerance
D. Cold hardiness
Shade-tolerant grasses can survive low light conditions without
thinning.
10. The primary reason for topdressing turf with sand is to:
A. Improve color
B. Level the surface and improve drainage
C. Increase fertility
D. Reduce mowing frequency
Topdressing fills low spots, smooths the surface, and improves
water infiltration.
11. Which soil test result would indicate a need to lime the soil?
A. pH 7.2
B. High potassium
C. pH 5.2
D. High organic matter
Lime is applied to acidic soils (low pH) to raise pH and improve
nutrient availability.
12. Pre-emergent herbicides are applied to control weeds by:
A. Killing established weeds
B. Enhancing turf growth
C. Preventing seed germination
D. Improving soil structure
Pre-emergent herbicides inhibit germination of weed seeds but do
not affect mature plants.

13. Which of the following is a warm-season turfgrass?
A. Kentucky bluegrass
B. Bermuda grass
C. Perennial ryegrass
D. Fescue
Bermuda grass thrives in warm climates and goes dormant in
cool seasons.
14. Integrated pest management (IPM) in turf focuses on:
A. Sole reliance on chemical pesticides
B. Ignoring minor pest issues
C. Combining cultural, biological, and chemical methods
D. Eliminating all insects
IPM emphasizes multiple strategies for sustainable pest control,
reducing chemical dependence.
15. Excessive nitrogen fertilization in turf can lead to:
A. Drought tolerance
B. Reduced disease susceptibility
C. Increased disease susceptibility and rapid growth
D. Enhanced root depth
High nitrogen promotes lush, soft growth, making turf more
prone to diseases.
16. Which irrigation method minimizes water loss due to
evaporation?
A. Overhead sprinklers during midday
B. Flood irrigation
C. Drip irrigation
D. Hand watering at noon
Drip irrigation delivers water directly to roots, reducing
evaporation and runoff.
17. A turf manager wants to prevent soil erosion on a sloped
lawn. The most effective strategy is:
A. Increase mowing height
B. Plant groundcover or grass with strong root systems
C. Apply more fertilizer
