Last week we had used a piece of equipment called the DryJect on our practice greens. The DryJect has been around for some time and has become a valuable tool for many superintendents. What it does is use a blast of high pressure water to make a hole and then magically, the same hole gets filled with sand. While it starts off messy, the result is a fabulous putting surface considering the cultivation just performed.
The objective for me on the practice greens with the DryJect was to not only incorporate sand into the hole, but also Profile. Profile is a porous ceramic material which aids in water retention. I am hoping to see better water retention on these greens than we are use to.
I performed it this time of year to try and mimic March weather, but of course it had to be 65-80 degrees the first week of November. I would like to stress that while extremely beneficial for the greens, this is in no way a replacement for core cultivation. I see this being fit for a course that can only aerate twice a year, but needs to do it four times a year and can't. The disruption is minimal which may allow for summer time cultivation.
