What is a key feature of low-volume bubblers in irrigation systems?

• A. They cover a large area quickly
• B. They focus on delivering water directly to plant roots
• C. They increase evaporation rates
• D. They require high pressure to operate

Answer: (B)

The key feature of low-volume bubblers in irrigation systems is that they focus on delivering water directly to plant roots. This targeted approach ensures that the water is applied directly where it is needed most, which helps maintain healthy root systems and reduces water waste. By saturating the root zone while minimizing surface runoff and evaporation, low-volume bubblers promote efficient water use, making them particularly beneficial in water-efficient landscaping practices. Watering directly at the root level encourages deep root growth and reduces the frequency of irrigation needed, leading to improved plant health and lower water consumption overall.
