Which irrigation method applies water in a fan shape over an area?

• A. Drip irrigation
• B. Fixed spray sprinklers
• C. Microspray
• D. Point-source drip

Answer: (B)

The irrigation method that applies water in a fan shape over an area is fixed spray sprinklers. This system uses a spray head that distributes water in a wide, circular pattern, creating a fan-like coverage over a specific area, which is ideal for lawns, gardens, and landscaped areas where uniformity is needed.

In contrast, drip irrigation targets roots directly and does not spray water in a fan shape. It is designed for efficiency by providing a slow and steady supply of water at the soil level, minimizing evaporation and runoff. Microspray systems can also distribute water in a more localized manner but they typically focus on a more concentrated area rather than a broad fan shape. Point-source drip irrigation, similarly, delivers water directly to specific points, typically at the plant base, without creating a fan-like distribution.

Therefore, fixed spray sprinklers are specifically designed to cover larger areas efficiently and effectively in a fan-shape, making them suitable for different landscape needs.
