In golf courses and ornamental garden lawns, the existence of earthworms is beneficial to the change of soil structure, enhances soil fertility, and degrades the pollution of heavy metals in soil.
But if there are too many worms, a lot of worm castings will accumulate on the level lawn, making many small raised mounds on the lawn surface.
For a long time in the past, chemical pesticides have been used to kill lawn earthworms. Although chemical pesticides have a certain effect on earthworms, most of these pesticides are broad-spectrum pesticides, which are too lethal and cause great pollution to soil and groundwater. This affects turf soil and other biodiversity and the cleanliness of surrounding water sources.
Therefore, the appropriate regulation and control of earthworm populations in ornamental lawns is very important.
