Which drip irrigation system uses polyethylene distribution tubing?

• A. Laser Tubing
• B. Point-Source Drip
• C. Soaker Hose
• D. Low-Volume Bubblers

Answer: (B)

Point-source drip irrigation systems utilize polyethylene distribution tubing to deliver water directly to the plant root zones. This type of system allows for precise placement of water, minimizing waste and ensuring that plants receive adequate moisture without overwatering. The flexible and durable nature of polyethylene tubing makes it ideal for various landscapes and allows for easy adjustments in layout as needed.

Laser tubing, on the other hand, is generally associated with specific applications that may not focus on the typical distribution method used in point-source systems. Soaker hoses operate differently, as they are porous and allow water to seep along their length rather than delivering it at specific points. Low-volume bubblers also have their own distinct mechanism, as they release water in a small area, which is not through continuous tubing like in a point-source system.

Thus, point-source drip systems, with their reliance on polyethylene distribution tubing, stand out as the correct choice in this context.
