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:

Recall the standard definition of soil texture and how particle size affects pore size and air movement in soil.

Answer 1

The Correct Option is A

Test each claim against basic soil physics. Texture is a particle-size classification, it tells you what fraction of the soil's mass is sand, what fraction is silt, and what fraction is clay. That is exactly what Statement (I) says, so it stands.

Now think about pore space. Clay particles are extremely small and flat, so they pack closely with mostly tiny micropores between them. Micropores hold water tightly but choke off free air movement, while sandy soils with large particles have big macropores that let air move freely. That means fine (clay-rich) soils will always aerate worse than coarse soils, ranging from medium to poor, which is exactly what Statement (II) claims.

Both checks pass, so both statements are true.

\[\boxed{\text{Both Statement (I) and Statement (II) are correct}}\]
