Divot Resistance in Golf Course Turfgrass

11.08.2011
Researchers hit the links to determine the divot resistance of several types of turfgrass

Golf courses, known for their calm scenic views and precise grass patterns, take daily abuse. Divots created by golf strokes are a common occurrence, and can be a costly problem for golf course maintenance operations. Although previous research has identified differences in divot recovery across species of bermudagrass and zoysiagrass, little is known about divot resistance.

Scientists at Purdue University and the University of Arkansas evaluated 12 cultivars of bermudagrass and zoysiagrass in a field experiment conducted in Fayetteville, Arkansas. Two golfers each hit three golf balls on each plot. The divots created by their shots were rated visually for divot type and severity, and the volume of displaced soil was measured.

The primary objective of this experiment was to quantify the divot resistance for various turfgrass cultivars. Researchers also compared evaluation methods for quantifying divot resistance. This study was published in the July/August 2011 issue of Crop Science.

‘Riviera’ bermudagrass allowed the largest volume per divot, while the smallest divots were observed with ‘Cavalier’, ‘Diamond’, and ‘Zorro’ zoysiagrass. The four methods used to evaluate divot resistance provided similar findings among the different grass cultivars and species tested.

“Due to the ease and speed as well as lower measurement variability of evaluating divot resistance, a visual rating for divot severity or a Turfgrass Shear Tester are recommended for future work in divot resistance,” explained Jon Trappe, a Purdue professor and the author of this study.

The results from this study demonstrate the differences and similarities in divot resistance that exist among various grass cultivars. Cultivars that are more resistant to divoting can help reduce maintenance inputs and costs. The research also demonstrates the need for evaluating the combination of resistance and recovery of divoting, as some grass cultivars have both improved resistance and recovery.

This research was partially funded by the Arkansas Turfgrass Association and the Golf Course Superintendents Association of Arkansas.

The Crop Science Society of America (CSSA), founded in 1955, is an international scientific society comprised of 6,000+ members with its headquarters in Madison, WI. Members advance the discipline of crop science by acquiring and disseminating information about crop breeding and genetics; crop physiology; crop ecology, management, and quality; seed physiology, production, and technology; turfgrass science; forage and grazinglands; genomics, molecular genetics, and biotechnology; and biomedical and enhanced plants.

CSSA fosters the transfer of knowledge through an array of programs and services, including publications, meetings, career services, and science policy initiatives.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
