Rafa beginning Ventilation process
As the tines are inserted, a cross like cut is created and these cuts result in much more area affected and open to air movement into (providing oxygen) and gases out of, the rootzone soil. A great feature of this tine is that while it affects a nice amount of underground area, the surface is minimally disrupted.
Green surface after "cross tine" ventilating, prior to rolling
After rolling the green following ventilating, ball roll is minimally, if at all, impacted, yet valuable benefits of oxygenation (aiding root system support) and rootzone soil drying (aiding surface firmness, and ball roll) are gained. This procedure may be repeated in the coming weeks if our current weather pattern of frequent rainfall continues.
Putting surface after rolling...surface nearly closed but ventilation channels beneath remain
As soil temperatures rise in the summer months, root growth slows and even ceases. And of course, without roots, plants weaken and ultimately die. Moist and/or saturated rootzone soils warm and retain heat more than drier rootzone soils and so anything we can do to dry and cool the rootzone, and retain roots, is critically important. Ventilation certainly helps in this regard!
