What is the application rate of fixed spray sprinklers?

• A. 0.5" - 1.0" per hour
• B. 1.5" - 2.0" per hour
• C. 2.5" - 3.0" per hour
• D. 1.0" - 1.5" per hour

Answer: (B)

The application rate of fixed spray sprinklers typically falls within the range of 1.0" to 1.5" per hour. This rate is significant because it allows for effective coverage of the landscape while minimizing water runoff and promoting efficient water use. Fixed spray sprinklers are designed to distribute water evenly across the area they cover, making them suitable for smaller garden areas and flower beds.

Understanding the correct application rate is crucial for determining the appropriate scheduling and duration of watering to avoid overwatering, which could lead to waste and runoff or underwatering, which may not meet the needs of the plants. This rate ensures that the water penetration meets the requirements of most landscaping plants, thereby fostering healthy growth and conserving water in a sustainable manner.
