There are a lot of worms in the soil.
If we put together all the worms living in a hectare of soil (in a football field), they would make a big heap and would weigh as much as two oxen.
Worms eat the remains of plants that are mixed with the earth.
Worms also eat a lot of earth.
You often see on the surface of the soil the little heaps of earth that worms have left.
Worms make a lot of holes in the soil.
Worms improve the soil structure.
By making holes and by eating earth, worms mix humus, sand, silt and clay. They work the soil like the farmer with his hoe.
So worms are very useful in the soil.
