Good afternoon, and welcome to another edition of Agronomy Weekly. Today's version will include information regarding our upcoming aerification process, as well as a current look at the course's condition.
Green heights are currently at 0.095" and will be raised slightly the week prior to aerification (July 10th and 11th). Fertility rates have been increased to promote quick growth and a denser putting surface. Speeds are typically reduced during these periods of growth, and we will rely on heavier sand topdressing, double mowing, and rolling throughout this process.
July 10th and 11th - aerate greens with 1/4" coring tines followed by dryject, aerate rough
July 17th and 18th - aerate tees, fairway, finish rough
Weather permitting, quarter-inch cores will be pulled from the greens on July 10th and 11th. The holes, which will be smaller than the size of a dime, will be filled with sand, brushed in, and followed by dryject. (Read more about the dryject process here.)
This process helps remove thatch and organic matter, improve drainage, reduce compaction, and increase air flow to the root zone. A higher rate of nitrogen, phosphorous, and potassium will be applied prior and post-aerification to promote a quick recovery. Heights will be lowered incrementally the following week until we reach our original height of 0.095".
Our goal for the weeks following the aerification process:
- Week of July 10th - greens cored, dryject followed by heavy topdressing and rolling throughout the week
- Week of July 17th - begin lowering height of cut incrementally
- Week of July 24th - reach our desired height of cut (somewhere between 0.095" and 0.105" depending on green speeds); should expect a two-week recovery on tees, fairways, and rough
Par 3 Carson Tees
Tee boxes on No. 13 and 17 are currently being expanded and will be re-leveled with sand. Work on No. 5 and 8 will follow in the coming weeks.
No. 6 Lake
A large portion of the grasses in our irrigation lake has been physically removed, and some is beginning to sink. Light treatments and removal will continue to help eliminate this grass over time.
Spot treatments followed by removing as much material as possible is crucial to the health of our lake. The breakdown and decomposition of these grasses requires the same oxygen our fish rely on to live. If treated in one application and left to decompose, the oxygen supply in the water could be depleted.
As always, I'm available at firstname.lastname@example.org if you have any questions or comments. Have a great week!
