A farmer in an arid agricultural region is concerned about water conservation and minimizing soil salinization in their fields. Based on the text, which irrigation method would be most recommended for this farmer?

  • A: Flooding fields, as it is a traditional method.
  • B: Using water from nearby rivers, as it is easily accessible.
  • C: Drip irrigation, because it requires less water and reduces salinization.
  • D: Relying solely on rainfall, as it is the most natural method.

Explanation

The text explicitly recommends drip irrigation for arid regions due to its water efficiency and ability to reduce salinization: 'Because drip irrigation requires less water and reduces salinization, it is used mainly in arid agricultural regions.'
