Question

Soil turning plough makes the furrow of which type (shape)?
A) ‘V’ shape
B) ‘L’ shape
C) ‘O’ shape
D) No definite shape

Answer 1

Hint: A plough or plough is a farm instrument used to loosen or turn the soil before planting or spreading seed. Ploughs were once pulled by oxen and horses, but now they are pulled by tractors on contemporary farms. A plough is equipped with a blade that cuts and loosens the soil. It has been crucial to farming for most of history. The first ploughs had no wheels and were known as aratrums by the Romans.

Complete answer:
The ditches dug by the plough are known as furrows. In modern times, a ploughed field is usually allowed to dry before being harrowed and planted. The composition of the upper 12 to 25 centimetres (5 to 10 in) layer of soil, where most plant-feeder roots grow, is evened out by ploughing and cultivating it. In some regions where soil damage and erosion are a concern, traditional ploughing has declined. Shallower ploughing or other conservation tillage methods are used instead.

The traditional shape of the soil turning plough is a curving metallic construction that initially runs straight, then horizontal, creating an L-shaped furrow. It is mounted to the rear of a tractor and is used to plough fields or spread seeds at predetermined intervals.

Thus the correct answer is option ‘B’.

Note: Ploughs were originally powered by people, but farm animals proved to be far more efficient. The first animals to be employed were oxen. Later on, horses and mules were used for a number of purposes. Steam engines were able to pull ploughs with the beginning of the industrial revolution. Internal-combustion-engine tractors overtook them in the early twentieth century.
