The first step in crop production is soil tilling. He digs the soil, does tilling with help of tractors and ploughs. This is done to loosen the soil particles so that air and nutrients can be easily absorbed.
The Earthworm is an organism which lives under the soil and makes burrows for itself. This burrowing action loosens the soil for better penetration of roots of the crops. It creates channels through the field which improves the physical properties of the soil.
