Adam, here's an article I pulled off Mike Clayton's web site
http://www.claytongolf.com.au a while ago when we were discussing Poa. It's written by one of Mike's turf gurus, John Sloan. I think more golfers would go for firmer conditions if it was a by-product of better turf.
Overwatering - the Number 1 Pitfall.
An article by John Sloan.
Recent articles in Golf Course Management magazines from the United States of America and the UK detail the 10 most common pitfalls of Golf Course Maintenance, complied by the USGA Greens Section agronomists, who visit nearly 1,700 different golf courses each year. The list is:-
1. Communication and Public Relations
2. Overwatering
3. Fast Green Speeds
4. Use of Pesticides
5. Continuity of Course Officials / Greens Chairpersons
6. Pesticide storage and / or maintenance buildings
7. Tree Management
8. Amount of Play
9. Labour: not enough and/or under qualified
10. Equipment: not enough and / or poor quality
This list or slight variations to it would likely be the same the world over, for apart from specific local problems, the principles of Golf Course Management are similar in most locations. If I was compiling a list of the most common pitfalls, number one would definitely be overwatering, for if there is a single common theme that quickly destroys turfgrass and playing conditions, it is the chronic misuse of irrigated water.
One of the great ironies of nature is that too much water is as detrimental as too little water and this fact is extremely pertinent to Golf Course Management where overwatering is a serious problem, not only from a turfgrass point of view, but also and more importantly, from a playing aspect.
Overwatering of Golf Courses is not ecologically or financially viable. Overwatered turfgrass is shallow rooted, requires more fertilisers, pesticides, mowing and aerification with the end result being poor and inconsistent playing conditions. So why are a large percentage of our courses being overwatered?
1. Player Pressure: A poorly struck shot will hold a wet, soft putting green more easily than a firm one and unfortunately there is a great deal of pressure placed on those in charge of golf courses to provide conditions which are sympathetic to poor shotmaking. The game commonly referred to as "Target Golf" is very much entrenched into a lot of golf clubs thinking.
2. Turfgrass Misconceptions: The more water one gives the turf, the shallower and weaker the root system becomes, the more water it then requires to survive - this is the overwatering treadmill. I recently visited a country Victorian Golf Course which, in my opinion, had been chronically overwatered for many years. The club asked what they could do to improve the playing conditions on the course, which were soft in free draining soils, unstable due to shallow root systems and unnaturally green because of the overuse of nitrogen based fertilisers. The simple answer to the club's immediate problem was to locate the on/off switch to the watering system and turn it firmly to the off position! The golf club was understandably concerned with this recommendation because "You would not believe the hot days we get up here". This is all the more reason why the club should dry the turf out, promote appropriate turfgrass, establish deep, solid root systems and let the players enjoy the benefits of playing on bouncy firm surfaces.
3. The Colour Green: We have become obsessed with the colour green, in particular that lush Augusta green and we mistakenly are led to believe that because it is lush green, it must be healthier than less greener grass. When I see lush green grass I think the golf course is overwatered, overfertilised and must cost a lot of money to maintain. Let us go back to playing golf on tough grass, not on green colour masquerading as a quality surface, for it takes little skill and foresight to overfertilise and overwater weeds, stripe cut them and pretend it is a quality surface. Our Golf Courses and golf would be far better off if the green was a little duller and we loved a little brown in our turfgrass.
To overcome the overwatering pitfall a sensible common sense approach to Golf Course Management is required. This may seem to be oversimplifying the problem but I think common sense is one of the first things forgotten when dealing with overwatering. Don't irrigate to satisfy the driest areas of your course, these areas require specific treatments, such as hand watering. Select and encourage turfgrasses which suit your area, don't artificially support poor quality, poor selected turf. Inspect your course regularly to ascertain watering requirements, no one can make that judgement except a suitably qualified person. Allow the turfgrass to "stress", make it hurt, and teach it that if it is going to be part of your clubs future turfgrass, it is going to have to toughen up, or find another place to reside.
The other big problem in coming to terms with overwatering is actually recognising that it is occurring. But it is safe to suggest that there are mote overwatered golf courses around than under watered ones, particularly in reference to the greens and tees. Who knows! Those problem wet areas on your course may just be chronic overwatering and those boggy Winter conditions just irrigation abuse during Summer and Autumn. So, if the only difference between playing your course in Summer or Winter is that in Winter you wear a jumper, do your golf and your turfgrass a favour, and closely examine your irrigation procedures.
