#PoaDay a virtual field day event hosted by members of university’s turfgrass and ornamental weed science team. The goals of the event are to educate turfgrass managers about the different strategies available for annual bluegrass control, Poa annua. This event is sponsored by AQUA-AID Solutions.
The Imants RotoKnife is a versatile and effective linear disc-aerator. The RotoKnife is designed to relieve surface compaction, improve aeration, reduce thatch buildup and remove surface water. By eliminating a PTO drive, the RotoKnife is fast across the surface and a versatile root zone management tool. The disc rotor shaft can be set in five different positions offering flexibility in working depth and linear spacing, allowing deep slitting to a depth of 6”, or shallow slitting at 2” spacing. The RotoKnife can even be used as a surface smoothing roller.
• Minimal surface disruption
• Increases soil’s ability to move water
• Increases aeration
• Excellent for managing thatch and black layer
