Spring Aerification

We just finished our Spring aerification.  We deep drilled 5/8'' holes 10'' deep on 5''x 5'' centers.  after that we came behind with our Toro Procore 648 and punch 3/8'' holes 3'' deep on 1.5''x 1.5'' centers.  Here is a little trivia for you.  We have a total of 2 acres of greens.  We drilled a total of 792,000 holes with the deep drill machines.  We aerified a total of 5,632,000 holes with our Procore.  A grand total of 6,424,000 aerifying holes in our greens.
     Aerification is used for gas exchange in the root zone.  O2 needs to get down to the root zone and CO2 needs to get out of the root zone.  The aerification holes gives the gases a channel to get in and escape.  We also aerify to eliminate thatch.  Thatch can cause multiple problems.  Soft spongy greens to increase disease and insect pressure.  Aerification is a very important cultural practice to have nice playing greens.
     You will notice the holes are much smaller than in past years.  We used smaller tines but punched twice as many holes.  Below are a few pictures of the process.  My staff did an outstanding job.  We aerified all 19 greens plus 9 white tee in one day.

 Look at the holes.  You can see the bigger deep drill hole below the keys.

 We used 35 tons of sand.
