Buffalograss Divot Recovery as Affected by Nitrogen Source and Rate

(by Evan Alderman and Jared A. Hoyle; KSU Turfgrass Research and Extension)

With increasing drought conditions and decreasing water supplies, drought tolerant turfgrass species are being explored for use on golf courses. With over 1.2 million acres of irrigated turfgrass in the United States, water conservation has become an issue throughout the turfgrass industry (Throssell et al., 2009). In recent years, the conversion from cool- to warm-season turfgrass species has become more acceptable in the transition zone. Golf courses in the Kansas City area converting tees and fairways from creeping bentgrass [Agrostis stolonifera L.] to zoysiagrass [Zoysia japonica Steud.] could reduce irrigation annually by 5,767,570 gal while reducing irrigation costs by up to $28,403 (Fry et al., 2008). In Kansas, the Ogallala aquifer provides up to 80% of the water used, although years of pumping has led to a steady decline in water levels (Buchanan et al., 2001). The use of drought tolerant turfgrass species would help conserve water supplies.

Buffalograss [Buchloe dactyloides (Nutt.) Engelm] is a native, drought tolerant, warm-season turfgrass species used for lawns, parks, athletic fields, roadsides, and golf courses in the Great Plains (Wenger, 1943; Beard, 1973; Fry, 1995; McCarty, 1995; Fry and Huang, 2004). Utilization of buffalograss on golf courses could lead to reduced water consumption while maintaining a reasonably dense playing surface.


Previous research has demonstrated that buffalograss can be maintained as an acceptable fairway turf with proper management practices. Buffalograss responds to nitrogen (N) fertility, and studies in Nebraska and Colorado have shown increased buffalograss quality, color, and growth with increasing N (Falkenberg 1982; Frank et al., 2004).



Golf course turf is frequently damaged by divots produced by players’ clubs when striking the ball. Although acceptable fairway buffalograss quality and playability can be achieved through proper fertility, divot recovery is of concern due to slow growth characteristics and minimal fertility requirements. Research is needed to evaluate buffalograss fertility management to maximize divot recovery. The objective of this study was to determine the influence of N source and rate on ‘Cody’ buffalograss fairway divot recovery.

Field studies were initiated in August of 2014 at the Rocky Ford Turfgrass Research Center (RF) in Manhattan, KS and July 2014 at Council Grove Country Club (CG) in Council Grove, Kansas. Mowing was conducted twice weekly at 0.625 in and 1.00 inch at RF and CG, respectively. After study initiation, irrigation was only applied to prevent drought stress and water in fertilizer treatments. To prevent drought stress, approximately 1.5 inch of supplemental irrigation was applied at each site over the experimental periods.

Treatments consisted of two N sources and four rates. Nitrogen sources were a quick release urea fertilizer (46-0-0) and a 120-day controlled release polymer-coated urea (PCU) (43-0-0). Nitrogen rates were 0, 1, 2, and 3 lb N/1,000 ft2. Nitrogen from urea was applied in two equal applications; one at study initiation and the other four weeks after initiation (WAI). All N from PCU was applied at trial initiation. Prior to treatment application, divots were created using a custom built edger.


Buffalograss’ low water requirements and its ability to be maintained at fairway mowing heights make it very valuable in low input turfgrass management systems. From the data collected in this study, applying a quick release N fertilizer at 1 to 3 lb N/1,000 ft2 will result in a shorter duration to reach 50% divot recovery compared to buffalograss receiving no N. Applying 1lb N/1,000 ft2 of a quick release product was determined to be the optimal fertilization rate to reach 50% divot recovery (2.5 weeks). This study has shown that under limited irrigation situations and with minimal fertilization, buffalograss exhibits improved divot recovery and, thus, playability in low input turfgrass management systems.

Establishing buffalograss in golf course roughs

(By Jake Reeves and Jared Hoyle, KSU Turfgrass Research and Extension)

Water restrictions and increased interest in sustainability are driving many golf course superintendents to consider new ways to save.  Ironically, one of the best new fits for saving in Kansas is one of the oldest ways around: buffalograss.  Buffalograss (Buchloe dactyloides) is actually the only widely used turfgrass native to North America. Many of the recent cultivars (Sharp’s Improved II, Bowie) grow denser and greener than their predecessors while not sacrificing their drought/cold tolerance, disease resistance, and other great characteristics. Traffic intolerance is one of the largest concerns for many superintendents, but a little traffic management can go a long way especially if coupled with cart paths. While not a perfect fit for every situation, buffalograss requires very little water, less mowing, and minimal nitrogen input to achieve an acceptable stand.

It is these characteristics that have many courses considering replacing their tall fescue roughs with buffalograss.  Once established, the courses could divert the money and time previously spent on their roughs to tees, fairways, and greens, ultimately rewarding a well-played round.

The end product is exciting for many superintendents, as their water bills would shrink. However, going through long periods of closing the course for renovations isn’t appealing to already cash-strapped courses.  Minimizing downtime and maximizing germination success with buffalograss seeding is a must if a course wanted to reduce the financial impact of the process.

We wanted to look at the most effective form of renovation from tall fescue roughs to buffalograss roughs without tilling the soil. This was to allow play to continue as long as possible on the course and keeping the renovation process very feasible for most courses.  Examining 3 different mowing heights and 4 different cultivation practices, our results will provide the most time and cost effective method for end users.

We are comparing a zero cultivation practice, aerification(2x), verticutting(2x), and slit seeding(2x @ 2lbs/M each pass)  against the 3 mowing heights (2.5”, 1.75”, 1.25”).  All cultivation practices except for slit-seeding were broadcast with Sharp’s Improved II buffalograss seed at 4 lbs/1000 ft2.  Traditionally, it is recommended that buffalograss seed be soaked for 3 days, changing the water every day, to encourage a quick germination upon seeding.  However, we did not soak the seed, believing the process not to be practical if a course was truly reseeding all of their rough.

Our results to date have shown that slit-seeding was the most successful method by far with aerification, verticutting, and zero cultivation decreasing in effectiveness in that order.  Slit-seeding mowed at 1.25” and 1.75” reached 100% cover 6 weeks after seeding (WAS) with minimal weed encroachment.  Ultimately, mowing height has had no effect except for a very slight lag in plots mowed at 2.5” compared to the two lowers heights. We hope to continue looking at fescue removal and buffalograss seeding in order to shorten the green cover loss experienced in the renovation process.
