#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.
Designed as a smaller form factor RotoKnife, the Imants Mini RotoKnife is a linear disc- aerator designed to relieve surface compaction, improve aeration, reduce thatch buildup and remove surface water. By eliminating a PTO drive, the Mini RotoKnife is fast across the surface and a versatile root zone management tool. The disc rotor shaft can be set in three different positions giving flexibility in working depth and linear spacing, allowing slicing to a depth of 4”, or shallow slicing at 2” spacing. The Mini RotoKnife is available in towed or mounted format and is compatible with most heavy duty utility vehicles and compact tractors. The Mini RotoKnife can even be used as a surface smoothing roller.

• Increases soil’s ability to move water
