Surface casting can result in a muddy and uneven playing surface and can interfere with quality and height of cut if casts build up on mower units. In golf turf, though, excessive production of earthworm faecal matter, commonly called ‘casts’, has many negative effects when casts are deposited above the turf canopy.
