Question

Given below are two statements:
Statement (I): The soil texture is defined as the relative proportion, by weight percentage of sand, silt and clay in soil.
Statement (II): The aeration in fine textured soil is medium to poor.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Clay-dominated fine soils have small pores, which restrict air movement.

Answer 1

The Correct Option is A

Step 1: Check the definition first. Texture describes the size distribution of mineral particles, sand, silt and clay, expressed as a percentage by weight. This is a standard textbook fact, so Statement (I) stands.
Step 2: Now reason about aeration from pore size. Coarse sandy soils have large pores and drain fast, giving good aeration. Fine clayey soils have tiny pores that retain water and restrict air movement, so their aeration is rated medium to poor. Statement (II) also stands.
Step 3: Since neither statement can be disproved, both are correct together.
