“…This was expected because more traffic stress is being applied. In our study, a greater decline in PGC and VQ of buffalograss was observed as the traffic rate increased, which is similar to past research that has reported a reduction in healing potential, clipping yield, and thatch thickness as the traffic rate increased on creeping bentgrass (Kohlmeier and Eggens, 1983), and a reduction in winter colorant green cover as the traffic rate increased on dormant buffalograss (Alderman, 2016). Under drought conditions, Braun (2017) reported a similar response to 16 passes/week of golf cart traffic on buffalograss at golf course rough height, which decreased PGC to 40 to 50% by the end of the 41-day drought period in both years, but quickly returned to above 75% PGC with the cessation of traffic and drought conditions.…”

“…Above-ground, turfgrass wear is associated with the abrasive scuffing, or tearing action on the leaf tissue from a golf cart tire (Beard, 1973). Management practices that may improve wear tolerance include maintaining an acceptable thatch layer, moderate levels of nitrogen (N) fertility, and high turfgrass shoot density (Beard, 1973;Kohlmeier and Eggens, 1983;Trenholm et al, 2000).

Limited information is available concerning the effects of nitrogen (N) and golf cart traffic rates on buffalograss roughs.• Increasing the N rate, especially from 0 to 1 or 1 to 2 lb N/1000 ft 2 /year, will increase the ability of buffalograss to better withstand traffic stress from golf carts in traffic situations.• Increased late season percent green turfgrass cover and turfgrass quality were observed when applying 2 lb to 3 lb N/1000 ft 2 /year on buffalograss roughs.• Buffalograss was able to maintain adequate green cover and acceptable quality with traffic rates up to 4 traffic passes/week. AbstractBuffalograss [Buchloë dactyloides (Nutt.) Engelm.] is increasing in popularity for use in golf course roughs in semiarid climates of the transitional climatic zone due to its low water requirements. Limited information is available concerning the effects of nitrogen (N) and golf cart traffic rates on buffalograss roughs. The objective of this study was to determine the influence of N rate and repeated simulated golf cart traffic on buffalograss maintained at golf course rough mowing height. Three field trials were initiated in July 2014 and 2015 in Manhattan, KS on 'Cody' buffalograss. Treatment factors were four N application rates (0, 1, 2, and 3 lb N/1000 ft 2 ) and five traffic application rates (0, 2, 4, 8, and 16 passes/week) with a custom-built golf cart traffic simulator. Regardless of traffic rate, as N rate increased, percent green cover (PGC), visual turf quality (VQ), and turf color increased. Results from this study indicate that an increase in N rate, especially from 0 to 1 lb N/1000 ft 2 /year and from 1 to 2 lb N/1000 ft 2 /year will increase the ability of buffalograss to better withstand traffic stress during the summer. Although, there may be minimal benefits of applying above 2 lb N/1000 ft 2 / year on buffalograss roughs. As traffic rate increased, regardless of N rate, buffalograss PGC, VQ, and turf color decreased, especially at 8 and 16 passes/week. Generally, buffalograss was able to maintain adequate PGC and acceptable VQ with traffic rates up to 4 traffic passes/week. We recommend that buffalograss turf managers carefully monitor traffic on buffalograss, especially in high traffic areas in the rough. Results show trafficked buffalograss can maintain adequate PGC and VQ when maintained at varying N levels.Buffalograss [Buchloë dactyloides (Nutt.)

Cultivar selection and nitrogen (N) fertility signi®cantly in¯u-ence the performance of creeping bentgrass (Agrostis palustris Huds.) in warmer regions of the United States. This study was conducted to determine the effects of N on root and shoot growth of three creeping bentgrass cultivars. The effect of three N rates (195.3, 390.6, and 586.0 kg Naha year) on the total root length density (TRLD), deep root length density (DRLD), visual shoot quality, shoot density, and root to shoot ratio (RSR) of Crenshaw',`L93', and`Penncross' creeping bentgrass were evaluated in the University of Georgia Rhizotron at Athens, GA. Over the 19 month study, cultivar type and N rate signi®cantly affected root and shoot growth with slight interaction. Crenshaw and L93 showed greater TRLD, DRLD, and visual shoot quality than Penncross at the 390.6 kg N rate. RSR was signi®cantly JOURNAL OF PLANT NUTRITION, 24(3), 535±548 (2001) 535 in¯uenced by N rate but not cultivar type.
