2. Which soil characteristic most directly affects plant root
development?
A. Soil color
B. Soil texture and structure
C. Fence height
D. Mulch color
,Answer: B. Soil texture and structure
Rationale: Soil texture and structure influence drainage,
aeration, water retention, and root penetration.
3. What is the main purpose of soil testing before planting?
A. To determine property boundaries
B. To identify nutrient levels and soil conditions
C. To determine the contractor's insurance premium
D. To select construction equipment
Answer: B. To identify nutrient levels and soil conditions
Rationale: Soil testing helps determine pH, nutrient availability,
and potential amendments needed for healthy plant growth.
4. Which soil generally drains the fastest?
A. Clay
B. Silt
C. Sand
D. Heavy organic soil
Answer: C. Sand
Rationale: Sandy soils have relatively large particles and pore
spaces that allow water to move quickly.

moisture retention, and adequate structure.
9. What does soil pH measure?
A. Soil weight
B. Soil acidity or alkalinity
C. Soil depth
D. Soil temperature only
Answer: B. Soil acidity or alkalinity
Rationale: Soil pH influences nutrient availability and plant
