Question

why do farmers turns soil in their fields​

Answer 1

The farmers turn the soil in their fields to up the fertile soil (which are mixes with humus) that are under upper soil, so that the upper soil mixes with fertile soil and hence the crop will grow well. It also provides the soil with more oxygen.

Answer 2

• During the summer, the top layer of the soil dries off, making crop cultivation impossible.
• In order to prepare the soil suitable for agriculture, various specialized and sophisticated instruments were used to plough the area throughout the summer.
• Ploughing in the summer is an important agronomic practise to ensure that the field condition is improved.
• Plowing also helps to prepare the ground for the next farming cycle.
• The top crust of the dry soil is removed, and the dirt underneath the top crust is overturned.
• By cracking the hard top crust of the soil, this approach provides significant benefits, such as increased infiltration capacity and permeability.
• Increased infiltration enables for greater moisture conservation, which the plant's root can then easily reach.
• Aeration is enhanced by tillage. Tillage promotes in the establishment of microbes that decompose other organic matter and allows for improved decomposition of toxic herbicide and pesticide residues.
• Summer ploughing guarantees that the sun's rays reach the deep soil, acting as a natural disinfectant by killing dangerous bacteria and fungus.
• It also destroys hibernating insects and pests' eggs, larvae, and pupae.
• The volume and depth of ploughing is determined by the severity of the weeds as well as the weather conditions.
• Note: Tillage is derived from the terms Tilian and Teolian, which imply "to plough," and hence "sowing seed" and "crop cultivation." Jethro Tull, known as the 'Father of Tillage,' has maintained that thorough ploughing is necessary to break down the soil into smaller particles suitable for agriculture.
