Matched Precipitation Rate implies what about sprinkler heads within a zone?

• A. Hydrozones
• B. Cycle & Soak
• C. Water Restrictions
• D. Matched Precipitation Rate

Answer: (D)

Matched precipitation rate means every sprinkler head within a zone delivers water at the same rate, so the depth of irrigation per hour is uniform across the entire zone. This is achieved by choosing nozzle sizes and operating pressures so that all heads, even if they look different, produce the same precipitation rate (inches per hour). When the heads match, areas near different heads receive the same water application, reducing overwatering there and under-watering elsewhere. This concept is distinct from hydrozones, which are based on plant water needs; cycle & soak, which is a scheduling technique to improve infiltration, and water restrictions, which are external limits.
