Yesterday was our first time using DryJect aerification on the Siebel Varsity Golf Training Complex greens. The DryJect machine utilizes a high pressure water jets to make small holes, then using the Venturi effect, sucks sand in to fill the holes. It is minimally disruptive, but very effective in opening up the thatch layer with a sand filled channel. Here is a short video showing the machine in action:
The results are impressive, as shown below in a core sample. A beautiful sand channel penetrates the surface thatch layer allowing water to easily flow downward into the profile.
