Which factor does NOT significantly affect the efficiency of a subsurface irrigation system?
64. Which factor does NOT significantly affect the efficiency of a subsurface irrigation system?
- Soil permeability
- Crop type
- Wind speed
- Depth of water table
Answer
The correct answer is: C) Wind speed
Explanation
Wind speed has little to no impact on subsurface irrigation efficiency because the water is delivered underground, unaffected by surface conditions.
