Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) - (III), (B) - (IV), (C) - (I), (D) - (II), (E) - (V)
• (A) - (IV), (B) - (V), (C) - (III), (D) - (I), (E) - (II)
• (A) - (IV), (B) - (V), (C) - (III), (D) - (I), (E) - (II)
• (A) - (I), (B) - (II), (C) - (III), (D) - (V), (E) - (IV)

Hint:

Remember the slope thresholds:
- Agronomic/Agricultural practices: \(\lt \) 2 %.
- Contour/Graded Bunds: 2 to 6 %.
- Terracing (Bench terraces): 10 to 30 %.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Soil conservation measures are classified into agronomic (agricultural) and engineering (structural) practices based on land slope limits and rainfall patterns.

Step 3: Detailed Explanation:
Let us match the structural/agronomic practices with their appropriate land/environmental limits:
1.

Engineering measures (A): Designed for sloped lands where erosion risks are high, typically on slopes greater than 2 %. Matches with

(IV).
2.

Agricultural practices (B): Simple crop management practices (contour tillage, mulching) that are highly effective on gentle slopes less than 2 %. Matches with

(V).
3.

Contour bunding (C): Recommended for low-rainfall areas on agricultural land with mild slopes of 2 to 6 % to retain rainwater. Matches with

(III).
4.

Graded bunding (D): Installed in high-rainfall regions (rainfall more than 750 mm/year) to safely drain surplus runoff. Matches with

(I).
5.

Terracing (E): Constructed on steep hilly slopes, typically ranging from 10 to 30 %, to convert the slope into a series of flat steps. Matches with

(II).
This yields: (A) - (IV), (B) - (V), (C) - (III), (D) - (I), (E) - (II).

Step 4: Final Answer:
The correct option is 2, which corresponds to (A) - (IV), (B) - (V), (C) - (III), (D) - (I), (E) - (II).
