Topdressing

It has been three weeks since we aerified the greens so I have resumed our normal light topdressings yesterday. Throughout the growing season I am topdressing every 7-10 days but with the cooler weather and shorter the days the turf has slowed down so I will be stretching our topdressing window to every 14 days until December. Once the turf has stopped growing I will prepare them for the winter including some venting, a heavy topdressing, possible deep tine aeration, and our snow mold protectant. The final step will be to use our three greens covers on our problem greens similar to last season.

In detail:

• venting provides voids in the soil to allow surface water from melting snow and ice a place to go. Reducing the chance for winter kill
• heavy topdressing will protect the crowns of the plant from dessication in the case of an open dry winter at the same time helping us dilute our thatch layer
• deep tine aeration allows for firmer and drier greens while providing deep channels for root growth; great time of year to implicate this procedure without disturbing play
• snow mold is a fungus that requires cold temperatures, free water (melting snow), and in-case certain cases snow coverage; our plant protectant will prevent snow mold from forming on the green and approaches

Frost

There is frost this morning and will be again tomorrow morning. Please call pro shop for updates.

Seedlings

The seed on the tees has germinated and is looking great. Another sign that aeration works.

Worm Casts

The fairways are covered in loads of small mud piles which is the result of equipment and carts running over worm casts. The casts are very dramatic on the 9th hole especially. The recent weather of cool wet and cloudy conditions combined with regular mowing and cart traffic has smeared these mud piles all over the turf. The reason some holes are worse then others is a direct result of where we have bentgrass n the fairways there are much fewer worm casts while areas that are predominantly ryegrass and Poa have much more casts. The bentgrass growing habit forms a tight dense "carpet" that the worms don't like to burrow through where as the ryegrass and Poa growing habit leaves voids where the worms make their way to the surface leaving the casts. Areas of shade created by structures or trees allow for conditions favoring ryegrass and Poa where as sunny locations favor bentgrass development.

Please check with the pro shop before your round to see if the "lift,clean,place" rule is in effect.

USGA October Update

The Long Season Comes At A Price

By Adam Moeller, agronomist, Northeast Region
October 2, 2012

Does everyone remember the excitement at your golf course when it opened early this spring? I didn’t think so. Golf facilities across the Northeast opened two to four weeks earlier than normal and the golfers certainly enjoyed using the course. Unfortunately, the earlier than normal start to the season has caused many facilities to exceed their pre-planned golf course maintenance budget. Higher than expected labor costs in the early part of the golf season now have many superintendents scrambling to maintain the golf course in the last few weeks of the season with a smaller than normal staff. If this is the case at your facility, it is important to realize that without adequate staff golf conditions are going to suffer, and the challenges of an early start to the season may now be evident.

The fall is a great time to get a lot of work done on the golf course. Teeing ground leveling, bunker renovations, tree pruning and removals and drainage work are some of the common fall projects at golf courses. These projects are similar to home renovations in many respects. There is some temporary disruption but ultimately they are being performed for the betterment of the golf course. In terms of their importance and priority, these are also similar to home renovations. Drainage work is like paying for a new roof. It can be costly depending upon the severity of the problems but there are not many projects that are more crucial.

Agronomic problems have slowed at most facilities in the Northeast. However, just a few weeks ago there were many golf courses that experienced significant disease in their rough, particularly gray leaf spot, leaf spot/melting out, and rust on perennial ryegrass and Kentucky bluegrass. In some cases this damage was severe and will require renovation and overseeding. Turf-type tall fescue is a great grass for rough because it is not susceptible to as many diseases as perennial ryegrass or Kentucky bluegrass, tolerates traffic well, and requires less nutrients and water than Kentucky bluegrass once it is mature. Fungicides can work well for disease control in the rough but their cost can be significant and the damage threshold may not justify their use for most facilities.

Annual bluegrass weevil damage was found on a golf course in New Jersey recently. This late damage is surprising but this pest continues to be the most challenging insect in the Northeast so anything seems possible at this point. Continue to scout for this insect over the next few weeks.

Is all this aerating working?

The answer visually comparing the greens from this season to last season would be yes but relying on the aesthetics of the greens alone could get us into trouble so we sample the greens to scientifically determine if we are making progress. The samples were taken from the 6th green in the rear section of the green where we experience thinning of the turf in the summer.

Green #6 is one of three USGA greens on a nine hole course that dates to 1896. The greens mix for the other two greens – which are not part of this report - was blended off site. Green #6’s sand and peat were mixed in the cavity with a rototiller. The comparison test data strongly suggests that the blending did not achieve an homogeneous mix.

This year’s test results found that the infiltration rate had increased from a sealed off 0.81 in./hr. to 6.69 in./hr. Air porosity similarly improved from 13.53% to 20.21%. Water porosity declined – a positive move – even though the amount of organic material in the top 2 inches increased substantially. 

Typically, an increase in organic matter equates to an increase in water retention.
The current hollow core program must be continued to reduce organic matter to more manageable levels. It is also needed to create consistency within the rhizosphere. Based on the comparison tests, we must expect that different areas will react differently based on having different properties. 

In simple terms we are making progress which will result in more consistent and healthy greens that can be maintained at a lower height of cut allowing for increased ball roll while maintaining a healthy plant.
