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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
