Dryject-ing greens.

This past Monday Dryject of North Texas came out and injected 26 tons of sand and soil ammendment into the greens.  Dryject uses water at 3200psi to 'blow' holes in the greens, which then creates a vacuum that pulls dry material into the holes.

It is one of the least invasive procedures that can be done to a putting surface that puts a lot of material in to the root zone.  Once the process is complete, the maintenance staff drags the greens with a soft drag mat, rolls the greens, and then they are ready to be mowed and played on.
