2013 Fall Project Update
Fall is Aeration season
• 22 man hours per hole for fairways• Followed by slit seeder to introduce new
seed into thin areas• Clean final appearance immediately when
finished
Necessary minimum 2x annually
Need to promote water and root penetration
Lack of roots due to compaction and consistent aeration
Turf being ripped up by
aerator due to no roots
• 200 man hours to complete greens aeration• Roll greens next day when dry for two days,
then mow with sand reels for 3 days, then roll and use good mowers
• Ongoing needle tining of greens every 4-6 weeks
• Aids in deeper roots and water penetration
• Aids in our Black layer battle• No disruption to play
Tee Aeration• First round complete• Second round will be a triple aeration
followed immediately by large roller to attempt leveling of some tees
• Sand topdressing to finish• Not sure of exact
start date, but will be soon
It has taken an EXTREMELY dry season for the following
issues to become as evident as they have
Irrigation Challenges• 1.95” of rain YTD against an average YTD of 11.43” last 4
years
• Approximately 10,000 feet of wire pulled and 136 heads repaired since May
• Estimate half complete for repairs to wiring, hoping to complete by end of year
Missing rear
nozzle
• Sprinkler is too low, has had wrong new internals installed, and has the wrong nozzles
• Hundreds to check
Due to all of this, the water runs downhill
creating a wet area and water does not go where necessary
Cause and effect
Why is there such a
dry spot right next
to a sprinkler?
Missing rear nozzle
• Proper nozzle installed at proper angle
• Hundreds to check
Incorrect nozzle combination, especially the rear that is shown
Correct nozzle combination. The red is the rear nozzle that sprays the base of the sprinkler
Hundreds of this style to check also
• Wrong new internal head with wrong nozzle setup
• After nozzle corrections were made 18 days later
• Missing rear nozzle impacts spray coverage and uniformity
• Potential water savings when all repairs complete
New sprinkler installed and only set to half circle in middle of fairway
Another new sprinkler installed to not water a full circle where
required
Sprinkler location
with nozzle issues
Old seeding grooves from last fall indicates annual dry spot
problems
More areas of annual dry spots
and seeding
• Manual water valve for a hose installed next to a sprinkler, indicating the need for extra water due to dryness
• This station of 3 heads is not in the automatic computer program
Hose valve
• Irrigation priority #1• Tree trimming and Permit area trimming• Seed and sod work• New clubhouse flowers for winter• Bunker rock removal• Questions or concerns?
Fall projects
We are all anxious to see this!!! Thank you for your attention.
