The heavy duty aerifier used for this doesn't punch a perfectly vertical hole, but goes in straight and then "kicks" the earth as it comes back out. This slight heaving of the ground helps to fracture the soil beneath, creating increased pore space for water penetration, gas exchange, and rooting.
One of the great things about this process is that it causes minimal surface disruption.
|You have to look closely to see the aerification holes on this fairway just a couple of days after the holes were created. The golf pencil and screwdriver have been poked into these holes.|
