Is This Where Our Season Is Heading?

Below is a video on the Drambuie World Ice Golfing Championship. I guess we could have it worse than we do with this cold spring. Weather like this all year would make my job awfully easy.

 

Why Can't We Play?



It is that time of year where we are put in the unenviable postition of deciding when to open the course for play. Unlike recent years, Mother Nature has not been very cooperative. Our average high for this week in 2012 was 79.7 degrees, compared to 42.1 degrees this year. Temperatures are forecasted to stay low and there is a chance for snow later this week. We will take all the moisture we can get, but like you, I am eager to get the season started. 

I have posted an excerpt from a USGA article below regarding the effects of winter play. I think it will help explain the position this year's weather has put us in. It should also explain what goes into the decision-making process in regards to allowing play. As always, thanks for your interest in what we do as well as your patience.

Repercussions of Winter Play
It is not hard to understand why many golfers are sometimes skeptical about claims concerning the negative effects of winter play, because to them the turf on greens that have been played throughout the winter usually appears the same as the turf on greens that have been closed. The effects of winter traffic, however, need not be obvious and dramatic to have significant and long-lasting repercussions.

Direct wear injury
Thinning of the turf due to direct wear injury is an obvious and important result of winter traffic. Unlike during the growing season, when turf is able to regenerate new leaves and stems to replace injured tissue daily, winter weather completely halts turf growth; the grass is continually thinned throughout the winter in direct proportion to the amount of traffic. This thinning of the turf canopy can, and often does, encourage the establishment of such weeds as Poa annua, crabgrass, goosegrass, moss, algae, pearlwort, spurge, and other weed pests during the spring and summer. True enough, weeds can indeed be a problem on greens that aren't subjected to winter play, but winter traffic causes them to be just that much more abundant and difficult to control.

Soil compaction
Soil compaction is a more subtle and perhaps more important consequence of winter traffic. Because of the cold winter temperatures and lack of active turf growth, the loss of excess soil moisture through evaporation and transpiration is greatly reduced. In addition, frozen sub-surface soils may completely block the movement of excess moisture through the soil profile. During the summer, a very heavy rainfall often creates soil conditions that warrant closing the course for a day or two until the excess moisture is eliminated by the way of evaporation, transpiration, and downward percolation through the soil profile. Because these moisture losses are often non-functional during the winter, saturated soil conditions can persist for weeks or longer. Yet the golfers who can appreciate the need to close the course during the summer are sometimes completely unsympathetic to the same conditions and concerns during the winter.

The effects of soil compaction on the health and playability of the turf are insidious at any time, but because wet soils are especially prone to compaction, the likelihood of traffic causing the collapse of good soil structure is of constant concern during the winter. As soil particles are compacted and pushed closer and closer together, the pore space that facilitates drainage and root growth during summer is gradually lost. As the season finally commences, golfers often complain the these compacted greens are hard. From an agronomic standpoint, turf begins the season in a weakened state, predisposed to a host of summer problems. In addition to the potential for weed encroachment, the turf on greens played during winter tends to wilt more readily during hot weather, and often is more susceptible to a wide array of primary and secondary disease organisms. 

Effects on playability 
With the loss of turf density from direct wear injury and the loss of turf vigor caused by soil compaction, greens played during winter tend to be hard, slow, and bumpy, and they are slower to develop during the spring, compared to greens that are not subjected to winter traffic. Footprinting is often a problem, and golfers tend to complain about the lack of trueness even after several topdressings in the spring. Finally, the effects of compaction on the health of the turf can last to a certain extent for much of the season, making it difficult or impossible to keep the greens as closely cut and intensively groomed as some golfers might desire.



Many winter golfers have heard these arguments before and have dismissed them as being ravings of overprotective golf course superintendents and turfgrass scientists. A favorite response is, "I pay plenty to play golf at this club, and I'm going to use the regular greens during the winter. That's why we pay the superintendent - to fix up the greens in time for spring. Besides, the Let-'Em-Play-Anytime Golf Course down the street lets them play through the winter, and they don't lose any grass during the summer. Anyway, we only have a few groups that play much during the winter. How much damage can we do?"

Winter play can do an inordinate amount of damage to the health and playability of the greens in relation to the number of rounds. Every golf course considering winter play should question whether or not it is worth the risk of damaging the greens and affecting their playability for a significant period of the regular seasonably allowing a relatively small percentage of the club's golfers to use them at that time. In the view of most golf course superintendents, turfgrass scientists, and agronomists, it is not. Unfortunately, even the considered opinion of the experts is unlikely to separate winter play from politics and religion as a topic of controversy among golfers.
