1. A landscape technician is preparing a soil bed for planting ornamental
shrubs. Which soil property most directly influences root penetration
and water movement in the soil profile?
A. Soil color
B. Soil texture
C. Soil temperature
D. Soil pH
B. Soil texture
Soil texture, defined by the proportion of sand, silt, and clay, directly
, affects pore size distribution, which governs water infiltration,
drainage, and ease of root penetration.
2. When installing a drip irrigation system, which component is most
essential for preventing emitter clogging due to sediment?
A. Backflow preventer
B. Pressure regulator
C. Filter
D. Timer controller
C. Filter
A filter removes suspended particles from the water supply,
protecting emitters from clogging and ensuring consistent irrigation
performance.
3. Which turfgrass management practice most effectively reduces soil
compaction in heavily trafficked lawns?
A. Fertilization
B. Aeration
C. Overseeding
D. Topdressing
B. Aeration
Aeration alleviates compaction by creating channels in the soil,
improving air exchange, water infiltration, and root growth.
4. A technician observes yellowing leaves with green veins on a plant.
This symptom is most indicative of which nutrient deficiency?
, A. Nitrogen
B. Phosphorus
C. Iron
D. Potassium
C. Iron
Interveinal chlorosis, where leaves yellow but veins remain green, is
a classic symptom of iron deficiency, especially in alkaline soils.
5. Which tool is most appropriate for pruning branches larger than 2
inches in diameter?
A. Hand pruners
B. Loppers
C. Pruning saw
D. Hedge shears
C. Pruning saw
Pruning saws are designed to cut thicker branches efficiently and
cleanly without damaging the plant.
6. What is the primary purpose of mulch in landscape beds?
A. Increase soil acidity
B. Enhance plant height
C. Reduce weed growth and conserve moisture
D. Accelerate flowering
C. Reduce weed growth and conserve moisture
, Mulch acts as a barrier against weeds and reduces evaporation,
maintaining soil moisture and temperature stability.
7. Which irrigation method is most water-efficient for shrub beds?
A. Flood irrigation
B. Overhead sprinklers
C. Drip irrigation
D. Hose watering
C. Drip irrigation
Drip irrigation delivers water directly to the root zone, minimizing
evaporation and runoff losses.
8. A soil test reveals a pH of 5.0. What amendment should be applied to
raise the pH?
A. Sulfur
B. Lime
C. Compost
D. Gypsum
B. Lime
Lime increases soil pH by neutralizing acidity, making nutrients more
available to plants.
9. Which mowing practice promotes healthy turfgrass growth?
A. Removing more than half the leaf blade
B. Mowing at the same height year-round
C. Sharpening mower blades regularly
