how do earthworms help the farmers? ( full detailed answer )
Answers
Answer:
The digging done by earthworms leads to aeration and drainage of the soil. In addition, plant nutrients are released from harvest residues that have passed through the earthworms’ intestines. Farmers can encourage earthworms by supplying large amounts of organic material and by using less disruptive soil tillage.
In a normal soil on an arable farm, there can be between 100,000 and 1 million earthworms, with a combined weight of between 100 and 1000kg, within one hectare. These earthworms play a very important role in the soil when they carry out their work.
Through their activities they increase the drainage and aeration of soil when they open up channels for water and air down to the subsoil.
