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.
What for ploughing is done?
Ploughing is the process of breaking, loosening the soil and turning it over for uprooting weeds and aerating the soil. ... It loosens the soil so that roots of crops can penetrate the soil easily. It brings nutrients to the surface thus making the soil fertile.
Why is ploughing done before sowing the seeds?
The soil should be ploughed thoroughly before sowing of the seed as this helps the roots to penetrate deep into the soil. This also brings the nutrient- rich soil to the top. Another advantage of this method is that the particles of weeds will be uprooted completely from the soil.
