Peak performance from putting greens and the role of organic matter

These slides were used for a seminar at Manila Southwoods Golf and Country Club organized by Nutranta Inc.

I explained how organic matter in the soil is affected by growth and by maintenance techniques. I also showed how organic matter in soil is measured using standard methods. I suggested that measurement of organic matter by loss on ignition from undisturbed samples may be a useful measurement for assessment and adjustment of the maintenance work.

    What do we want? • 100% grass cover • some

    expectation of that continuing • ball roll • ball bounce
  3. 3.

    Management of organic matter Increase growth & OM • fertilizer

    (N) • irrigation Reduce OM • sand topdressing • core aerification • solid tine aerification • verticutting

    Recommended approach Check surface zone (0 to 20 mm) organic

    matter once a year Then, compare the OM change to: • annual N rate • annual sand topdressing amount • annual aerification impact
