Separating areas with sun and shade on an irrigation system is called what?

• A. Hydro-zoning
• B. Geo-zoning
• C. Chromozoning
• D. Sun-shade zoning

Answer: (A)

Separating irrigation areas by sun exposure and the plants’ water needs is hydro-zoning. The idea is to group areas that share similar evapotranspiration rates and moisture demands so each zone can be watered appropriately. In practice, you assign sunny, high-water-use areas separately from shaded or low-water-use areas, giving them different runtimes, valve settings, or emitter types. This makes watering more efficient and helps prevent overwatering or underwatering. Terms like geo-zoning or chromozoning aren’t standard, and sun-shade zoning isn’t the established term for this concept.
