1. c) Ploughing

2. b) Levelling

3. a) Sowing

Before the seeds are sown, the soil must be ploughed and levelled so the seeds can obtain maximum nutrients from soil.

1. Ploughing: The upper layer of the soil is exposed to external environment and may get depleted of its nutrients. Hence, ploughing is used to turn over the upper layer of soil, which help provide aeration to the roots and in bringing fresh nutrients to the surface. It also pushes down any weeds that may be growing to lower layers so they can degrade.
2. Levelling: It breaks down any big pieces of soil crumbs which ensures uniform aeration
3. Sowing: It is the process of putting seeds into the soil.
