Answer 2

Answer:

Hello!!!!!

---------------------

Land ploughed is pressed very lightly to set the seeds down firmly in the ground.

If the land is pressed hard then the seed will encounter a lot of pressure and not be able to germinate properly as the delicate shoot will not be able to break its way out of the hard ground

The ground is tilled before farming to loosen up the soil and seeds are scattered on it the places where the seeds are scattered is pressed and watered immediately and sprayed with pesticides to keep insects away.
