Golf course architects and builders have found the latest recommendations by USGA beneficial. It has helped golf courses across the globe to maintain high quality playing conditions, deliver consistent and healthy turf for years. The updates of the recommendations have to be reviewed for construction techniques and material testing to ensure the Putting Greens Services in Tempe AZ is successful in the construction method.
The first recommendation was published by the USGA in the year 1960 for Method of Putting Green Construction. Early putting greens were constructed using native soil or sand mixture and organic matter. The drainage was a big issue and was often unavailable. The materials used were not consistent and this lead to construction mishap. Over a period of time, with expectations of golfers increasing and advancement in Putting Greens techniques in Tempe AZ, more consistent putting green built was required to meet the demands of the playing conditions. During the course of time revisions happened in the years 1965, 1968, 1973, 1982, 1989, 1993 and 2004. These focused on providing supporting materials.
The goals of the revisions were:
• Determine the sustainability of materials used in putting green construction
• Improve the clarity and maintain the broad relevance of present recommendations to ensure it is useful to the playgrounds around the world
• USGA is responsible for developing educational literature along with the revised recommendations. This literature will help to improve awareness and enhance understanding of principles and scientific research to support the recommendations
• An updated document reflecting the modern construction techniques and latest technologies used to provide assistance to golf course builders in succeeding in building putting green
Summary of changes
The shape of the subgrade can determine the drainage. There is no need to conform to the proposed surface contours but the gravel layer has to be close to the finished grade. For this purpose geotextile fabric used in between the gravel layer and the subgrade soil would prove helpful.
Drainage is a crucial factor that could affect the life of the putting green. Trenches to a minimum of 8 inches deep has to be dug. The drain lines have to be no more than 15 feet. The main line needs to be extended to a short distance from the high side of the green for clean out port installation. A perimeter drain along the low edge needs to be installed and shall extend towards the first laterals.
Type of gravel used has to be stable and retain shape, like the pea gravel. The gravel must pass the LA abrasion test or the ASTM test. The soil lab will determine the need for intermediate sand layer and the relationship between the particle size of the gravel. In case of sand layer requirement it should not be more than 10% of the gravel and needs to retain ½ inch sieve and 65% must pass through.
The revision of the USGA recommendation may not change the Method of Putting Green Construction drastically but will definitely refine the methods. The recommendations are widely researched and are widely used by Putting Greens Services in Tempe AZ. The USGA has helped to provide positive results to golf courses over a period of time. The revised recommendation is expected to arrive in early 2018.
