These soil profiles are all examples of DryJect holes/channels.  The DryJect blast creates a 3-dimensional column, encouraging more side to side growth between DryJect columns than coring/tining holes.  There is no glazing of the DryJect column, which can often be found in a hole created by coring/tining.  The end result of DryJecting is Phenomenal root growth and increased dillution of organic matter.  The DryJect process allows the turf manager the ability to introduce larger volumes of dry material into their rootzones than by topdressing and dragging or even hand brooming techiniques.  Dryjecting accomplishes all of these advantages while still maintaining a remarkably smooth puttting surface, allowing for scheduling flexibility.
