After clearing a new farmland, the next implement that will be used for the next farm operation is a plough.

A plough is a farm implement that is used to loosen and turn over the soil, making it ready for planting. It is usually pulled by a tractor or animals, such as oxen or horses. The plough has a blade that cuts through the soil and flips it over, exposing the nutrient-rich lower layers and burying the weeds and crop residues from the previous season.

By ploughing the land, farmers break up compacted soil, improve drainage, and create a loose seedbed for planting. This allows the roots of the crops to penetrate the soil easily and access nutrients and water. Ploughing also helps to control weeds by burying their seeds and disrupting their growth.

In this question, the other options listed are different types of farm implements, but they are not typically used immediately after clearing a new farmland.

For example, a harrow is used to break up clods of soil and smooth the surface after ploughing. A ridger is used to create ridges or furrows for planting certain crops, such as potatoes. A cultivator is used to loosen the soil and remove weeds during the growing season. A planter is used to precisely place seeds or seedlings into the soil.

Therefore, the correct answer is Option E: plough, as it is the most suitable implement to use after clearing a new farmland.
