Why do farmers Plough a field?

Ploughs help to prepare the soil for seeding or planting crops: creating open furrows by dragging through the soil. The faster the land can be tilled, the more food can be produced. In order to keep growing healthy crops in not-so fertile areas, the earth needs to be churned up so that nutrients come to the surface.

Why do we Plough the soil before sowing seeds in physics?

ploughing turn the soil loosen it and increase its fertility . Loose soil is porous ,well aerated and holds more water. Roots of a plant can penetrate deep into the lose soil and breath easily in it .

What is the purpose of a plough?

plow, also spelled plough, most important agricultural implement since the beginning of history, used to turn and break up soil, to bury crop residues, and to help control weeds.

Why is ploughing necessary before sowing the seeds give three reasons?

to increace the porocity of the soil. to make the soil loose and comfortable for a plant to grow. to make sure that the plant derives nitrogen from atmosphere. to increase the fertility of the soil.

Why do we Plough our lands in physics?

Ploughing of fields is essential as it breaks the fine capillaries in the soil, thereby saving the loss of excess water which rises in the capillaries and evaporates.

Why is ploughing important give two reasons?

ploughing helps to increase the friendly microbes and worms in the soil which helps in further turning of the soil. ploughing makes the soil loose, which makes the plants easier to breathe through the porous soil. 3. ploughing kills the weeds present in the soil and suffocates them to death.

Why was the plow invented?

It was used for farming to break up tough soil without soil getting stuck to it. When was it invented or first used? John Deere invented the steel plow in 1837 when the Middle-West was being settled. Wood plows couldn’t plow the rich soil of the Middle-West without breaking.

Why is it important to Plough the field?

The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh nutrients to the surface while burying weeds and crop remains to decay. Trenches cut by the plough are called furrows. In modern use, a ploughed field is normally left to dry and then harrowed before planting.

Why do farmers plough the field during summer physics?

Summer ploughing ensures that the rays of the hot sun reaches the deep soil and hence works as a natural disinfectant by destroying the harmful bacteria and fungi, it also kills the eggs, larvae and pupae of hibernating insects and pests.

Why do farmers plough the field explain your answer with reference to capillary action?

Soil water rises to the surface by capillary action and evaporates. To conserve soil water, the farmers plough their fields in summer. The loosening of the top layer of the soil breaks up the fine capillaries through which the deeper down water is sucked up. Thus the loss of water in the soil is prevented.

What are the advantages of ploughing before sowing seeds?

Loosening of soil can improve air circulation. The roots can penetrate deeper into the soil, thus holding the plant firmly. Ploughing enhances the water retention capacity of the soil. Ploughing uproots the weeds growing in the field and aids in the growth of microbes.
