Question

why during ploughing the land is pressed lightly not tightly

Answer 1

During plowing the land is pressed lightly because of the following reasons:

a) the soil will get loosely compacted so that they can be properly exposed to the sun.

b) Nutrients, when sprinkled, will be able to reach beneath, or else fellows will destroy the nutrients if tightly pressed.

c) Microorganisms will be able to persist suitably in loosely bound soil, rather than tightly packed.

Answer 2

Answer:

Ploughing is done mainly in the Autumn, after harvesting the crops, to turn over the soil, leaving it in furrows. This covers and suppresses weeds. Also, on heavy soils, the furrows are left for winter weather to break down the soil particles. In Spring, as soon as the soil has dried out a little, the furrows are harrowed and broken down into a file tilth suitable for planting or sowing with seed.
