Fairway Deep Tining

Deep tine aerification...



Deep tine aerification

On Monday, April 22nd a contractor will be arriving to perform a new type of aerification to our fairways called deep tining. Deep tining uses a special type of aerifier that is different than the aerifier that we have used in the past.  Traditionally we use an aerifier that pulls a 2” deep core of soil from the fairways.  Although this is a beneficial process,  after years of aerifing at the same depth, a hardpan has formed in the soil beneath this 2” depth.  This compacted layer leads to reduced water infiltration.  The effects of this compacted layer is most evident after a rain event when puddles form in our fairways and remain wet for several days. 

Deep tine aerification has the ability to penetrate up to 8 inches deep in the soil profile depending on the soil type.  Then after penetrating the soil, the aerification tine rocks forward creating a heaving action.  This heaving action further cracks the hardpan and alleviates compaction.  The channels that are formed by this process allow for surface water to drain off the fairway creating a firmer and drier playing surface.

Here is an image explaining some of the benefits of deep tining;

In addition to the improved drainage, deep tining will also promote deeper rooting.  Deeper roots equate to healthier turf, which in turn can better combat drought, heavy traffic and attacks from turf diseases and insects.

From a playability standpoint the best part of deep tine aerification is that it doesn't leave behind a muddy mess like the core aerification.  That is because instead of bringing up a core of soil to the surface, the deep tine machine uses a solid tine that simply pokes a hole in the fairway.  The fairways should be ready for play as soon as the process is complete. 

Deep tine aerifiers operate slowly so the contractor will use several machines to complete the process as quickly as possible.  The fairway deep tining should be completed by Tuesday.  We appreciate your patience as we complete this important procedure.
