Question

Drip irrigation is most suitable for

• A. Acid soil
• B. Alkaline soil
• C. Saline soil
• D. All the above

Hint:

Drip irrigation continuously leaches salts to the periphery of the wetted zone, minimizing salinity stress in the crop root zone.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Micro-irrigation provides localized, high-frequency water application directly to the crop root zone.

Step 2: Detailed Explanation:
Drip irrigation maintains a continuous high matric potential in the active root zone, keeping soil salts in dilute solution and constantly pushing dissolved salts toward the outer perimeter/fringes of the wetting bulb.
This prevents salt accumulation in the immediate rhizosphere, making drip irrigation exceptionally suitable for cultivating crops in saline soils and using saline water.

Step 3: Final Answer:
Therefore, drip irrigation is most suitable for saline soil.
