“…No seedbed preparation resulted in less than 10% buffalograss cover regardless of seeding rate. Dissimilarly, Frank et al (2002) observed 55% 'Cody' buffalograss covers three MAP with minimal seedbed preparation (lightly raked 2.5 cm deep into the soil surface) when seeded a rate of 98 kg burrs/ha and Frank et al (1998) observed 23% buffalograss cover at two different locations three MAP when seeded at 100 kg burrs/ha. Buffalograss cover (44% and 75% at 146 kg • ha -1 and 195 kg • ha -1 , respectively) was significantly higher for topdressing as a seedbed preparation compared with no seedbed preparation (8% and 10% at 146 kg • ha -1 and 195 kg • ha -1 , respectively) ( Table 2).…”

“…The present water supply concerns in western Texas and other areas of the arid Southwest have led to the examination of buffalograss as a viable option for managed turfgrass environments (Frank et al, 2002(Frank et al, , 2004. Research efforts have identified buffalograss as a reduced irrigation and fertilization input turfgrass relative to traditional turfgrass species grown in the arid Southwest (Frank et al, 2004).…”

Growing concern over the sufficiency and variability of present water supplies in the arid Southwest has led to the examination of buffalograss [Buchloe dactyloides (Nutt.) Engelm.] for water conservation. Increasing acceptance of buffalograss will require investigation into conversion techniques for its establishment. The objectives of this study were to evaluate the effects of seedbed preparation and seeding rate on the establishment of buffalograss after bermudagrass desiccation with glyphosate. Research was conducted at the Texas Tech Quaker Research farm in 2009 and 2010 on a mature ‘Riviera’ common bermudagrass [Cynodon dactylon (L.) Pers.] rough. Bermudagrass was sprayed with glyphosate at 1.1 kg acid equivalent (ae)/ha 5 and 1 weeks before seedbed preparation. Plots were scalped after desiccation. Treatments were arranged in a two × four factorial, randomized complete block design with four replications. two buffalograss seeding rates and four seedbed preparation treatments. Seedbed preparation treatments consisted of no seedbed preparation, topdressing alone (0.6-cm layer), hollow-tine aerification + topdressing, or verticutting + topdressing. ‘TopGun’ buffalograss was planted on 1 June 2009 and 4 June 2010 at 146 or 195 kg·ha−1. Grid counts were conducted to determine buffalograss cover one, two, and three months after planting (MAP). Counts were then converted to percent cover (0% to 100%). Greater buffalograss cover was observed when seed was applied at the higher rate (196 kg·ha−1) except within treatments that did not receive seedbed preparation treatment. No seedbed preparation resulted in unacceptable buffalograss cover. Percent buffalograss cover three MAP was 75%, 83%, and 86% for topdressing alone, aerification + topdressing, and verticutting + topdressing treatments seeded at 195 kg·ha−1, respectively.

“…In low‐input turfgrass management systems, past research has shown that buffalograss responds positively to applications of urea. Frank et al (2002) demonstrated that rates of urea (46–0‐0) up to 3 lb N/1,000 ft 2 resulted in 27% more buffalograss cover at season end compared with 0 lb N/1,000 ft 2 in an establishment study. In the present study, we observed that applying urea at rates up to 3 lb N/1,000 ft 2 enhanced buffalograss’ recuperative abilities compared with untreated turf; however, the 1 lb N/1,000 ft 2 rate was adequate for optimal divot recovery.…”

Core Ideas Buffalograss treated with urea to provide 1 lb N/1,000 ft2 achieved 50% divot recovery 6.3 days faster than untreated turf. Polymer‐coated urea applications did not improve divot recovery rates compared with the 0 lb N treatment. Under limited irrigation situations and with minimal fertilization, buffalograss exhibits improved divot recovery and, thus, playability in low input turfgrass management systems. Divots occur when a golfer's club impacts the surface and removes turf. No published research has been conducted to explore the influence of nitrogen (N) fertility on divot recovery in buffalograss [Buchloë dactyloides (Nutt.) Engelm]. The objective of this study was to determine if nitrogen source and rate influence divot recovery in buffalograss. Research trials were initiated in 2014 at the Rocky Ford Research Center (RF) in Manhattan, KS and Council Grove Country Club (CG) in Council Grove, KS. Three divots were created per plot using a modified edger. Urea (46–0‐0) served as the quick‐release N source, and polymer‐coated urea (PCU) (43–0‐0) was the controlled release N source; each was applied to provide 0, 1, 2, and 3 lb N/1,000 ft2/yr. Buffalograss treated with urea to provide 1 lb N/1,000 ft2 achieved 50% divot recovery 6.3 d faster than untreated turf; however, the 3 lb N/1,000 ft2 rate did not enhance divot recovery in comparison. Polymer‐coated urea applied the day of divoting did not improve divot recovery rates compared to the 0 lb N treatment. Acceptable divot recovery is possible in buffalograss with a quick‐release N source and N fertility levels as low as 1 lb N/1,000 ft2/yr.

“…This treatment washes out unwanted salts and other materials and has been found to be beneficial. Turfgrass on golf greens requires fairly high amounts of fertilizer inputs, especially at the time of establishment (Frank et al, 2002). These fertilizer inputs coupled with daily irrigation plus flushes and the high porosity of the golf greens could lead to fertilizer nutrients being added to surface waters from drains that often discharge to the surface.…”

Normal and Flush Irrigation Effects On Phosphorus Leaching from Simulated Golf Greens in the Greenhouse

Fertilizer nutrients have the potential to leach from porous golf greens, especially when "flushing" is practiced where 8 or 10 cm of irrigation is applied. A greenhouse experiment was carried out with 52 cm columns (15 cm diameter) made to United States Golf Association green specifications and sodded to 'Tifdwarf' bermudagrass to determine the amounts of phosphorus leached for two fertilizer sources (20-20-20 and superphosphate) at three rates (0, 5, and 11 kg ha −1 added every other week for a total of 6 weeks) and two irrigation schemes (normal irrigation at 6.3 mm day −1 and the same irrigation with an additional four flushes of 8 cm each). Weekly leachate collections for 29 weeks were analyzed for soluble P. Flushes resulted in higher P concentrations in the leachate where as much as 40% of the added P was recovered in the leachate. In contrast, normal irrigations resulted in less than 10% of the P applied moving through the columns. The two fertilizer sources gave essentially similar results. The higher P rate caused higher concentrations of P in the leachate, but P concentrations for the low rate for normal irrigation were not different than the control. For flushes, the extractable P in the top 15 cm of the rooting media was lower than for normal irrigation and the extractable P in the columns was higher. Results indicate that low rates of P should be applied to golf greens and, if flushing is practiced, it should be done when little P is in the rooting media.
