“…Use of digital image analysis allowed for a more accurate measure of salinity tolerance during vegetative growth than visual rating methods used in previous studies (Marcum, 2001;Rose-Fricker and Wipff, 2001;Pessarakli and Kopec, 2008;Wang et al, 2011;Koch and Bonos, 2011b).

“…Although a multitude of screening methods have been used under greenhouse conditions to evaluate turfgrass salt tolerance (Greub et al, 1985;Marcum, 2001;Rose-Fricker and Wipff, 2001;Pessarakli and Kopec, 2008;Qian et al, 2007;Koch et al, 2011;Wang et al, 2011), few have included enough entries to allow for ranking of cultivars within several different species. Establishment of salt-tolerant turfgrass cultivars can help mitigate the effects of salts in irrigation water or the soil environment.…”

Turfgrass may experience significant salt stress due to poor water quality, insufficient leaching, or exposure to environmental contaminants. Establishment of salt‐tolerant turfgrass cultivars is one possible method of mitigating the effects of salts in irrigation water or the soil environment. The objective of this research was to evaluate the relative salt tolerance of cool‐season turfgrasses in a controlled environment using digital image analysis. Six replications of 74 cool‐season turfgrasses were established using recommended seeding rates in 10.16‐cm by 10.16‐cm pots of silica sand for 12 wk, and suspended in two 760‐L tubs of half‐strength Hoagland solution. Following an adaptation period, all pots were exposed to salinity levels of 4, 14, and 24 dS m−1 successively, each for 2 wk. Digital images were collected after each exposure level using a custom light box, and analyzed for percent green tissue. Cultivars of tall fescue (Festuca arundinacea Schreb.) were found to be most salt tolerant, with ‘Wolfpack II’ and ‘Jaguar 4G’ performing best after the 14 and 24 dS m−1 exposure levels, respectively. Many fine fescue entries performed well, including slender creeping red fescues (Festuca rubra L. ssp. litoralis) ‘Sealink’, ‘Seabreeze GT’, and ‘Shoreline’. Trial entries found to have consistent salt tolerance at all levels may be used to guide recommendations for turfgrass managers and breeders and have potential for use in salt‐tolerant mixtures.

“…Seaside II is a salt tolerant cultivar (Marcum, 2001) and T-1 is a newer cultivar with high shoot density (Brilman, 2005;Jones and Christians, 2009). The plant materials were maintained in a greenhouse with temperatures of 20/10°C (day/night), a 14-h photoperiod, and minimum midday photosynthetically active radiation of 400 μmol m -2 s -1 supplemented with metal halide lamps.…”

Evaluation of creeping bentgrass (Agrostis stolonifera L.) salt tolerance often showed inconsistent results. The objective of this study was to investigate the reactions of ‘Seaside II’ and ‘T‐1’ to NaCl, Na2CO3, Na2SO4, and CaCl2, each at concentrations of 0, 25, 75, 125, 175, and 225 mM. Chlorophyll a (Chla) content was the lowest in the CaCl2 treatment followed by Na2CO3 and Na2SO4 and highest in NaCl whereas chlorophyll b (Chlb) content was lowest in Na2CO3 followed by CaCl2 and Na2SO4 and highest in NaCl. Turfgrass visual quality and green density were reduced the most by the Na2CO3 and CaCl2 treatments. Evapotranspiration (ET) decreased in the order of treatments CaCl2, Na2SO4, Na2CO3, and NaCl at 1 wk after treatment (WAT), but at 4 WAT there were no difference among CaCl2, Na2SO4, and Na2CO3. Significant salt type × concentration interaction existed, and the first order or second order coefficient of regression equation ranked the changing rate of physiological parameters differently in different salts. Leaf K+:Na+ ratio was affected differently by salts and a threshold of 1 appeared at different salt concentrations depending on salt types and cultivars. The pH, osmotic potential, and electrical conductivity of salt solutions were confounded making the interpretation of mechanisms of physiological stress difficult. Nevertheless, this study showed that different salts rank creeping bentgrass salt tolerance differently.

Irrigating turfgrass with treated effluent water has become a common practice in response to shrinking supplies of potable water. Newly developed decentralized water treatment systems produce recycled water containing varying quantities of N on short notice. Using such tailored water to irrigate turf areas would reduce or eliminate the need for additional mineral fertilizers if concentrations of nitrate in the water were raised during the growing season to meet the annual N requirement. On the basis of our estimates, in order for turfgrasses to receive their entire annual N requirements (20 to 25 g N m−2 yr−1) solely from effluent irrigation, nitrogen concentrations in irrigation water would need to range from as low as 11 mg L−1 for arid regions with a 12‐mo growing season to more than 50 mg L−1 in areas with only a 6‐mo growing season. Furthermore, tailored water should be applied with advanced irrigation systems with high distribution uniformity to minimize nitrate leaching. Subsurface irrigation systems distribute water more efficiently and uniformly and minimize human exposure to treated effluent, which would help dispel negative public perceptions regarding the use of effluent to irrigate public turf areas. As the use of treated effluent for turfgrass irrigation continues to increase, the idea of adjustable nutrient content in irrigation water combined with a subsurface irrigation delivery system could become an important means to sustainably maintain much‐needed urban green spaces.
