Answer 1

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

The correct options are
A Increases water holding capacity
B Aids growth of earthworms and microorganisms
D Brings nutrient rich soil to the top

$\bullet$ The process of loosening or turning the soil is called ploughing.
$\bullet$ Loosened soil is better aerated and allows the roots of plants to penetrate deeper.
$\bullet$ It also aids the survival of earthworms and microorganisms which add nutrient-rich humus to the top soil.
$\bullet$ Ploughing also brings underlying nutrient rich soil to the top for plant usage.
