This will be fun to follow: 100 courses in 100 days

This will be interesting, and you might like to follow along too. Paul Jansen, the golf course architect, will be traveling to 100 golf courses in a span of 100 days. All the courses are in SE Asia, and he is starting in Bali on 19 March and ending in Bangkok on 28 June.

Bali's a great place to start. The last time I played golf in Bali I birdied the 6th, 7th, and 8th at Nirwana Bali, just missing a hole-in-one here at the famed 7th.

Paul's itinerary lists all the courses he will visit. He writes that he will "use the opportunity to highlight the richness and diverse nature of the golf experiences across the entirety of South East Asia." That will certainly be interesting, although I'm more looking forward to the serendipitous and surprising things that are sure to happen.

Perhaps visits to a few hidden gem courses that aren't on the written agenda? The food from so many different cuisines. I've had some great meals in the places he is going to visit. How's his stomach? No food poisoning, I hope. Traffic? Missed flights? Adjusted schedules. Mistranslations. Lost in the countryside and not speaking the language? No internet access? There are so many things that can happen on this adventure, and I'm looking forward to following along.

Paul has promised to take lots of pictures and to keep us updated. He will be sharing updates on a regular basis, maybe even daily. You can follow along at:

He's got quite a busy schedule during those 100 days, but I will try to catch up with him at one or two places along the way. I can't wait to hear what he has to say after actually doing this.

Malaysia International Golf Symposium 2013: Registration & Program

2013_Malaysia_International_Golf_Symposium_Registration_ Form.pdf (1 page)On October 21 to 23, the Malaysia International Golf Symposium 2013 will be held at The Royal Selangor Golf Club and at The Royale Chulan Hotel in Kuala Lumpur.

Registration is now available through the Malaysian Golf Association.

I will be speaking about Nutrient Requirements for Golf Courses in Asia and then giving another presentation on Selection of Grass. Both of these topics are ones I am excited to speak about and are ones that I have studied extensively over the past few years.

The program includes other presentations about turfgrass management, including one on the Latest Trends in Golf Course Maintenance by Andy Johnston, along with additional talks on a range of subjects related to course design, construction, and club management.

Webcast from the Australian Turfgrass Conference: Micah Woods on grass selection in Asia

Grass_selection_asia_video_micah_woods
The Australian Golf Course Superintendents' Association provide a great service by making so many of the presentations from their annual conference available for online viewing

At the 27th Australian Turfgrass Conference in Adelaide, I gave presentations about turfgrass nutrient requirements, about grass selection, and about managing turf in microclimates.

In this presentation about grass selection, I spoke primarily about manilagrass (Zoysia matrella), bermudagrass or green couch (Cynodon), and seashore paspalum (Paspalum vaginatum). You'll see in this video representative photos of the different grasses and will learn how manilagrass persists and provides a fine turf even with minimal maintenance. In Southeast Asia, seashore paspalum tends to be overtaken by bermudagrass, you will see, and bermudagrass tends to be overtaken by manilagrass. This short video makes a case for using more manilagrass and less bermudagrass and seashore paspalum.


A Plot of Cities Where Warm-season Grasses Grow, and more

cities plotted by sunshine, temperature, and rainfall

I made the bubble plot above to see how the differences in temperature and sunlight and rainfall between cities would appear if plotted this way. The data are from climatological normals provided by national meteorological services and the World Meteorological Organization, collected in some cases from the climate section of a city's page on Wikipedia.

I made this plot for a few reasons. I saw a job posting for a superintendent position in Asia saying that experience working in a Florida-type climate would be desired, and I wanted to plot a few cities this way to see how cities in Asia compared with Florida. Someone also asked me if I thought it was more difficult to manage warm-season grasses in Singapore or in Florida, and I thought that a plot such as this might make my answer more clear. And I also notice as I travel that a grass that grows so well in Honolulu, for example, may not grow well at all in Bangkok. There are clear differences in suitability of grasses for different growing environments. And as I work with some new software, I saw a tutorial to make this type of bubble plot on the FlowingData website and I wanted to try it for myself.

City_by_sun_edit-1 When plotted this way with mean annual temperature on one axis and hours of sunshine on another axis (the area of the circle for each city is proportional to annual rainfall), one can see that the cities in Asia tend to have a higher annual temperature, have less annual sunshine than the cities plotted from the USA, and have substantially more precipitation. A quick look at the bubble plot shows that Singapore, for example, has about 60% the sunshine of Miami while receiving almost twice the rainfall. 

This doesn't tell the whole story about which grasses perform best in a certain area. We can also consider the winter temperatures, the summer temperatures, the timing of rainfall and dry seasons, etc., but simply plotting by temperature and sunshine tells us a lot. 

Turfgrass managers in Southeast Asia know that zoysiagrass (Zoysia matrella) and broadleaf carpetgrass (Axonopus compressus) thrive in this climate while bermudagrass maintained as a turfgrass struggles. This type of plot helps us to understand why. At the Marukatayawan Palace in Thailand, we see that zoysia grows in the sun and broadleaf carpetgrass covers the shaded areas under the trees.

Carpetgrass_zoysia

These native grasses thrive when maintained as turfgrass in this region, while grasses such as bermudagrass which have a higher light requirement cannot compete with zoysia even in full sun. Why is that? Because even in full sun, there is still relatively little sunshine in Southeast Asia compared with Florida.


Collecting Dollar Spot With Dr. Tredway in Southeast Asia

Lane_khao_yai Turfgrass pathologist Dr. Lane Tredway from North Carolina State University recently made a visit to Southeast Asia for the purpose of collecting dollar spot samples. From ATC's Thailand base, we went to Vietnam, Malaysia, and the Philippines to collect dollar spot from many different grass types: bermudagrass, zoysia, seashore paspalum, carpetgrass, creeping bentgrass — even from some sedges. There is not much creeping bentgrass in Southeast Asia but we traveled to high elevations to find it at Dalat in Vietnam, at the spectacular Mount Kinabalu Golf Club in Sabah (below), and at Camp John Hay in Baguio.

Dr. Tredway has chronicled this trip in a post entitled Dollar Spot Expedition to Southeast Asia on the Turf Diseases website

Dollar_paspalum_khaoyai Dollar spot is ubiquitous and is especially so on seashore paspalum turf. This project looks at the different strains of dollar spot as they are found on different grass types and in different geographical and climatic areas. The idea is that a better understanding of the dollar spot pathogen itself will allow for the development of better control measures for this disease in the future.


Research on Weed Populations in Malaysia

Weed_malaysia One of the papers I found most interesting last year was Characterizing Weed Populations in Different Turfgrass Sites throughout the Klang Valley of Western Peninsular Malaysia (Uddin et al., 2010). Weeds are one of the biggest challenges facing turfgrass managers in tropical Asia. Uddin's survey of 53 sites in the Klang Valley included seventeen athletic fields, six sod farms, nineteen residential lawns, and eleven golf courses.

In total, 79 different weed species were identified in this survey, with 63 of the species being found in lawns, 29 on athletic fields, 25 on sod farms, and 23 on golf courses. Some of the most pervasive weeds were the sedges Cyperus aromaticus and Cyperus compressus along with grasses Chrysopogon aciculatus, Eleusine indica, and Digitaria fuscescens.

In three bermudagrass fields, 37 weed species were found. In three manilagrass (Zoysia matrella) fields, there were less than half as many species present. Only seventeen weed species were found in the manilagrass fields compared with 37 in the bermudagrass fields. Wiecko (2000) wrote about the challenges of growing bermudagrass in tropical Asia and this survey confirms quantitatively what turfgrass managers in Asia see every day: bermudagrass is easily infested with weeds, while manilagrass produces a dense sward that has comparatively few weeds.


Seminar Report from Saujana

Woods_bakar I've just returned to Bangkok after the Sustainable Turfgrass Management seminar held at Saujana Resort on October 26 & 27. This event was supported by The R&A and was presented by Saujana in partnership with The R&A, the Malaysian Golf Association, Golf Course Superintendents Association of Malaysia, Asian Golf Industry Federation (AGIF), and ATC. John Geary, Environmental Agronomist from the Australian Golf Course Superintendents Association, spoke about water management plans, preparing for drought and managing turfgrass through drought conditions, and on irrigation water quality and grass variety trials conducted at Australia.

Irr_audit

Kenne James (from Toro) and David Patterson (from RainBird) gave a presentation on optimized irrigation of golf course turf on behalf of AGIF and during the field seminar demonstrated the procedure for measuring the distribution uniformity (DU) during an irrigation audit. I found this session especially helpful. Understanding how much water is applied and where it is applied and how one's irrigation system is operating in the field is critical to the maintenance of high-quality playing surfaces. James and Patterson provided a number of helpful tips to ensure that an irrigation system will operate at its optimal level of efficiency.

Woods_field_seminar Geary and I spoke during the practical session about optimizing the rooting system of turfgrass, techniques on organic matter control for putting green turf, and the importance of organic matter management in general, and on problem-solving techniques, drainage, and a host of other topics as we had a look round the newly-renovated Bunga Raya course at Saujana. During the classroom session, I gave seminars on grass selection for golf courses in SE Asia, irrigation water quality, and golf course renovation with more discussion of grass choices. It was an excellent program at a superb venue with an engaged and inquisitive audience.
