Where is water placed in drip irrigation?

• A. At the plant's root zone
• B. Over the leaves
• C. In the air
• D. At the surface of soil

Answer: (A)

Water is applied at the plant's root zone. Drip irrigation delivers water directly to the soil around the roots, usually near the base of the plant, so the moisture is readily available where the roots can absorb it. This targeted delivery makes the system highly water-efficient, wasting far less water through evaporation or runoff. It also keeps leaves dry, which reduces disease risk. Wetting leaves or spraying water into the air doesn’t provide water to the roots and wastes resources, while surface wetting alone can lead to uneven moisture and shallower rooting. Placing water at the root zone supports steady, deep soil moisture that supports healthy root development.
