• B. Aids growth of earthworms and microorganisms.
• C. Creates more surface area for nitrogen fixation.
• D. Brings nutrient rich soil to the top layer.

Answer 1

Answer: (A), (B), (D)

Brings nutrient rich soil to the top layer.

The process of loosening or turning the soil is called tilling or ploughing. It is one of the basic steps followed before a crop is sown.
Advantages of the process are:
$\bullet$ Loosened soil is more aerated and allows the roots of plants to penetrate deeper.
$\bullet$ It aids the survival of earthworms and microorganisms which add nutrient-rich humus to the top soil.
$\bullet$ It brings underlying nutrient rich soil to the top for plant usage.
