Abstract/Contents:"Earthworm casting is a highly destructive problem on golf course fairways around the world. In the Pacific Northwest, the predominant earthworm species depositing cast on the turfgrass surface is Lumbricus terrestris. The purpose of this project is to evaluate clipping removal, soil acidity, and sand topdressing for their effects on earthworm casting. A field study is being conducted to determine if clipping removal, aoil acidity, and sand topdressing for their effects on earthworm casting. A field study is being conducted to determine if clipping removal alone or in combination with hollow-core aeration treatments will reduce the food supply and decrease earthworm casting on fairway height turf composed of annual bluegrass (Poa annua), creeping bentgrass (Agrostis palustris) and perennial ryegrass (Lolium perenne). The whole plots are clippings removed versus clippings returned. The sub-plots are hollow-core aeration in the spring, spring and fall, and no hollow-core aeration. In a separate 2-year experiment, sand topdressing in combination with acidifying fertilizers (ammonium sulfate and ferrous sulfate) is being evaluated for its effects on earthworm casting. The eight treatments include five different combinations of ammonium sulfate, ferrous sulfate, and sand topdressing. Dolomitic lime and an organic fertilizer (Milorganite) are also being included to evaluate for increases in casting. The results of both studies approximately indicate that clipping removal, soil acidity, and sand topdressing have no consistent effects on casting deposited on the turfgrass surface by L. terrestris earthworms."
