2. Healthy topsoil is important because it:
A. Prevents all weeds
,B. Provides nutrients, water retention, and root support
C. Eliminates the need for irrigation

Rationale: Quality topsoil supplies nutrients, retains moisture, promotes
drainage, and provides structural support for healthy root growth.
These characteristics are essential for successful landscape
establishment.
3. Soil pH primarily affects:
A. The color of mulch
B. Nutrient availability to plants
C. Sprinkler pressure
D. Concrete curing time
Rationale: Soil pH influences how easily plants can absorb essential
