Grass and soil for sports turf in Thailand

Grass and soil for sports turf in Thailand

This is a presentation I gave for a seminar at Bangkok Thonburi University in July 2018. I explained, for Thailand's climate, how I would work with grasses and soils to achieve these goals:

- Suitable gradient and free from dips and hollows​
- Well drained​
- Good grass cover of desirable grass species​
- Firm and stable to give good playing characteristics​

Those are some of the "main characteristics of the playing surface that need to be achieved," taken directly from FIFA's "Manager's Guide to Natural Grass Football Pitches."

  2. Today • Grass varieties • Grass management • Soil •

    Basic requirements • Ideal requirements

  7. Goal • Suitable gradient and free from dips and hollows

    • Well drained • Good grass cover of desirable grass species • Firm and stable to give good playing characteristics • Appropriate pitch markings with a good visual appearance
  8. Grass varieties

  9. Bermudagrass Cynodon dactylon • The standard grass for sports fields

    in hot and sunny climates • Grows rapidly when conditions are good • Does not grow well in shade • Does not grow well in wet soils
  10. Seashore paspalum Paspalum vaginatum • Grows better than Cynodon in

    shade and in wet soils • Requires regular irrigation • Susceptible to diseases and insects • Best grass for use with saline irrigation water
  11. Manilagrass Zoysia matrella • Best all-around grass for Thailand conditions.

    It grows everywhere. • `Nuwan noi' variety grows more rapidly than bermudagrass or seashore paspalum in Thailand conditions. • Excellent resistance to traffic.
  12. Experiment at TISTR • Cynodon, Paspalum, and Zoysia • Sand

    rootzone • 15 mm cutting height • 1 g N/sq. meter/week • 0.5, 1, and 2 g K/sq. meter/week
  13. Surprising result? • Zoysia grew more than Cynodon or Paspalum

  14. Use grasses with rhizomes and stolons • Cynodon, Paspalum, and

    Zoysia
  15. Use grasses with rhizomes and stolons • Polytrias indica: good

    for lawns, not for football. Stolons but no rhizomes.
  16. Use grasses with rhizomes and stolons • Axonopus compressus: no

    rhizomes
  17. Use grasses with rhizomes and stolons • Axonopus compressus: no

    rhizomes
  18. Grass management

  19. Light 6 hours per day at minimum.

  20. Air in the soil • at least 25% of the

    soil volume should be air space • Easiest to achieve with a sand rootzone • Manage compaction and organic matter
  21. Air in soil • Easy way to check. • After

    25 mm of rain or irrigation, can you squeeze water from the soil? If so, too much organic matter and not enough air space.
  22. Water • Supply enough to maintain grass growth.

  23. Fertilizer • Supply enough to produce the desired growth rate.

    • Probably about 1 g N/sq. meter/week as a starting point. • Soil test to find out what the soil can supply.
  24. Insects, diseases, and weeds • First, maintain a dense stand

    of healthy turf. • Second, control as necessary. • With healthy turf in a well-drained soil, weeds and diseases will be a minor problem on football pitches in Thailand.
  25. Mowing • Mow with sharp mower blades. • Cut at

    appropriate height, usually from 20 to 35 mm. • Mow frequently enough to remove no more than 33% of the leaf at one time.
  26. Soil

  27. Use a sand rootzone • In Thailand's climate, a sand

    rootzone is required for a quality pitch.
  28. Sand rootzone with sub-drainage • Standard method is similar to

    golf green construction • Subdrainage • Gravel layer • 30 cm rootzone layer
  29. At minimum • 5 cm sand topdressing layer over soil

    • Drainage at 4 m spacing • Slit drains filled with sand at 90 degree angle
  30. Basic requirements

  31. Basic • Drainage • 5 cm sand layer • Mow

    3x per week • Ability to supply irrigation • Sprayer for use as necessary in weed, insect, and disease management • 6 week break at end of season for field renovation and regrowth • Resod areas as necessary • Others?
  32. Ideal requirements

  33. Ideal • In addition to basic: • 30 cm sand

    rootzone • Irrigation system • Use growth regulators • 10 week break for renovation and repair • Mowing more than 3x per week • More frequent aeration and verticutting • Others?
