Why do we loosen or turn the soil?

Loosening the soil is important because it:

allows the toots to go deeper into the soil and yet, breathe easily (allowing air to reach the roots),

helps in growth of microbes and earthworms that add humus to the soil and turn and loosen the soil further, and

nutrient-rich soil comes to the top and can be used by plants.

The process used to loosen and turn the soil is called Tilling or Ploughing. After tilling, Levelling is donein which the big clumps of soil called crumbs are broken (and levelled). Levelling the field helps in the process of sowing and irrigation.
