As decomposers (decomposers), earthworms play a central role in the breakdown of organic substances. Earthworms form burrows as they migrate through the soil (soil).
Which insects are decomposers?
Along with springtails, arachnids are the most common ground arthropods. Because the diversity is so great, it is difficult to classify the mites into groups in the soil.
Can you hear earthworms?
The earthworm cannot hear, but if you tap the earth it will feel the vibration. That’s why he comes out of the earth.
How deep do earthworms go?
The corridors are up to 20 meters long per square meter and in some cases even reach up to seven meters deep. When digging, earthworms direct considerable force outwards.
What does the excretory organ do in the earthworm?
Each ring contains a pair of funnel-shaped excretory organs that remove excess fluid from the body. Under the outer skin lies the skin-muscle tube. This consists of one layer each of circular and longitudinal muscles.
What can you do against earthworms?
Apply sharp-edged, lime-free sand (lava sand is recommended) (4-5 L/m²)
Sweep this into the turf after it has dried. The worms avoid the sandy surface because they cannot process the sand with their digestive tract.
Should the worms nevertheless come to the surface, the droppings will be mixed with the sand, dry out more quickly and break down more easily without causing significant damage to the grasses.
It may be possible that the area has to be sanded twice a year.
The best times are spring and autumn.
The sand layer should not be thicker than 1 cm.
The sand dries out quickly and can cause dry damage to the grass during sunny periods.
What can you do about worms in the lawn?
Walk on the lawn as little as possible.
Let the lawn dry with the mounds of earth!
Distribute coarse sand or lava chippings in the lawn.
Thoroughly remove grass clippings.
Allow the lawn to dry faster
Are worms good for the lawn?
However, the earthworms in the lawn are extremely useful animals. The earthworms belong to the so-called macrofauna in the soil. They help to convert dead organic matter in the soil. Their lively activity also leads to better aeration of the soil and promotes the formation of the crumb structure.
What to do against worms in the garden?

What are decomposers biology?
Destruents (from the Latin destruere = to break down) are living beings that convert organic substances into inorganic substances. Also called decomposers, reducers or (re-)mineralizers. Decomposers break down low molecular weight organic molecules for energy production (metabolism).
What does an earthworm sound like?
We have assumed that the earthworm does not make any noise when moving. This is how we did our research: We put an earthworm on a coffee filter and heard very clearly that it crackled. We found out by looking closely at pictures that the earthworm has bristles on its abdomen.
