Greens Aeration September 9 and 10

Greens aeration is scheduled for Monday September 8 and Tuesday September 9. Nine holes will be completed at a time by the turf management staff. Listed below are the four main benefits of greens aeration. 

1. Improve Playability - The minor disruption in the playing surface immediately following core aeration ultimately helps improve playability. Removing cores helps create a firmer and faster green with increased plant health and density. It also improves the smoothness of the greens in conjunction with sand topdressing.

2. Removal of Organic Matter - Removing organic matter, commonly known as thatch, is crucial to a healthy green. Too much organic matter buildup in fine turf restricts water infiltration causing wet conditions on top, and dry, hydrophobic conditions deeper in the soil. It also ties up valuable nutrients needed by the plant and can cause a "sponge-like" surface vulnerable to mechanical injury.

3. Increase Pore Space - Removing cores creates much more pore space for oxygen. Oxygen is essential to the root system of a putting green. Without a strong root system, putting greens will not be able to weather the hot and humid summers. As the cooler weather slows down the top growth of the grass plant, the root system goes into overdrive as it works to create a deep mass of roots for the next season.

4. Improve Water Infiltration - The channel created by the removal of a core allows for a higher percolation rate of water. This channel of fresh sand is free of organic matter and allows for much faster drainage. This creates a drier and more firm playing surface that protects from wear associated with saturated soil conditions.

The labor intensive process of core aerating greens is absolutely necessary for the health and great playability of golf course putting greens. The few days of disruption seems like a minor inconvenience when you are able to provide many months of great conditions afterwards. The desired putting green conditions of today's golfer are not achievable without core aeration.

Not Your Typical July

The month of July can be unbearably hot and humid in Southwest Ohio. The last two years, however, have been atypical. The temperatures have been unseasonably cool and reminiscent of fall. These cool days have certainly been welcomed by golf course superintendents and anyone that enjoys outdoor activities. According to the National Weather Service, Dayton did not officially reach 90 degrees for the month of July, only the 8th time since 1893. In addition, this past July was the third coolest July on record behind July 2009 and July 1984. This month has also come with above average rainfall once again. Many of the rain events have been severe causing flash flooding and bunker washouts. The chart below lists weather information over the past 4 years during the month of July and leaves us wondering what August will bring?

2014 Mid Season Update

The 2014 golf season has certainly been interesting. The year got off to a very cold and wet start. During the months of April, May and June, we recorded 6.17", 5.97", and 6.53" of rain respectively. Much of the rain recorded was from severe storms causing flash flooding and bunker washouts. The golf course maintenance staff has fixed bunker washouts a total of 10 times so far this season, taking nearly 50-60 man-hours to repair each time. All of this unexpected bunker labor has made it challenging to complete other routine tasks. During the month of June, the heavy rains were coupled with high humidity. This caused disease pressure to go through the roof, requiring shorter spray intervals on fine turf. With these less than ideal conditions, our turf never suffered. Our strong agronomic programs have helped us provide exceptional turf quality and playing conditions. Moving into July, Southwest Ohio is experiencing temperatures 10-15 degrees below normal and low humidity. Perhaps Mother Nature feels like she owes it to us after the awful weather patterns over the previous 6 months. The long range forecast continues to look beautiful. Hopefully everyone can get out to enjoy several rounds of golf.
