Ground contours & grass

This presentation was given as part of the Design, Build, & Maintain: a different way? seminar at Laem Chabang on 8 March 2015.

I explained two things. First, once a sandcap is in place, a tremendous amount of work must be done to keep that surface firm. Second, growing grasses that don't die or thin out when allowed to grow slow, or when irrigation is reduced, will produce the firmest surfaces.

  2. 1. Soil Yes, such surface conditions are possible, but sandcapping

    is not the way to achieve them. all referenced articles are at bit.ly/grass_contour
  3. What happens when we grow turf in sand? 1. Sand

    has low water holding capacity – we have to add more water. 2. Sand has low nutrient holding capacity – we have to add more fertilizer. 3. When more water and fertilizer are added, the grass grows more.
  4. Once a sandcap is in place, the organic matter must

    be managed. organic layer over sandcap Singapore
  5. If the organic matter is not managed, greens fail. Once

    a fairway is sandcapped, that same work of organic matter removal and dilution with sand must be done on the entire sandcapped area. sandcapped seashore paspalum fairway, Hong Kong
  6. “The long-term health of putting greens depends on maintaining sand

    as the primary medium. If organic matter accumulates beyond a reasonable degree, the physical benefits of sand are diminished and putting green physical properties decline along with the health of the turf.”
  7. “The end result is a well- drained, stable, sand- based

    field at a fraction of the cost required for other renovation processes.”
