Above: you can see the benefit of DryJect looking at this cross section our root zone. The bright white sand are the channels created by the machine.
It's that time of November when we have to disrupt the putting greens for the benefit of great putting surfaces for years to come. Even though we DryJect two directions on the same day, this process still isn't as disruptive as hollow coring greens with 1/2" tines on a 2x2 hole spacing. This machine shoots blasts of high pressure water into the green, fracturing the soil to a 3-4" depth. Following those blasts of water, "oven-dry" sand is pulled down into the void that was created by the water. This is such a great practice for greens for a number of reasons. There is one thing it doesn't do however, and that's removing organic matter (cores) like traditional aeration does. To that point, DryJect does not replace traditional aeration, it's simply another tool we add to our overall putting green management program at Highlands CC. In March, we'll be doing more aggressive hollow tine aeration to remove the organic matter that accumulates below the surface. By doing this, we are able to keep the putting surfaces firm and fast.
