Question

Which of the following is NOT an advantage of soil preparation?

• A. It allows roots to breathe easily.
• B. It restricts the roots from penetrating deep into the soil.
• C. It mixes nutrients uniformly.
• D. It aids in the growth of organisms like earthworm.

Answer 1

The correct option is B It restricts the roots from penetrating deep into the soil.

Soil preparation involves loosening or turning of soil. Due to this, the nutrients which are present at lower levels of soil are brought to the surface. And helps in mixing nutrients uniformly.
$\bullet$ It also allows the roots to penetrate deep into the soil and allows the deeply penetrated roots to breathe easily by making the soil loose.
$\bullet$ The loosened soil helps in the growth of earthworms and other microbes present in the soil.
