Q: Does overhead irrigation or drip irrigation use less water?


Read this paragraph and choose the correct option from the provided answers:

Irrigation is the single biggest use of water. Overhead irrigation wastes a lot of water. Drip irrigation wastes a lot less. Figure below shows a drip irrigation system. Water pipes run over the surface of the ground. Tiny holes in the pipes are placed close to each plant. Water slowly drips out of the holes and soaks into the soil around the plants. Very little of the water evaporates or runs off the ground.

 Choices:

- mist irrigation

- stream irrigation

- constant flow

- drip irrigation


A:
drip irrigation
