Background: Increasing nitrogen (N) plant uptake efficiency may result in better plant quality and growth, less N susceptible to leaching and potential contamination to surrounding environments. Soil surfactants have been documented to increase water infiltration and enhance water uniformity throughout the soil profile. Thus, applying a surfactant may increase N uptake and use efficiency. Methods: To investigate this theory, four treatments were applied to bermudagrass grown in leaching columns filled with one of three soils (sand, sandy loam, and sandy clay loam): (1) 10% alkoxylated polyols and 7% of glucoethers surfactant with 15N labeled urea, (2) 10% oleic acid esters of block copolymer surfactant with 15N labeled urea, (3) water with 15N labeled urea, and (4) water without 15N labeled urea. Ambient 15N was determined by the no surfactant and no urea treatment. Each treatment combination was replicated five times and the greenhouse experiment was repeated. Bermudagrass quality and density, leachate volume, and volumetric water content were determined over a 28d period following application. Determination of 15N recovery in plant, soil, and leachate occurred at experiment termination. Results: Applying either surfactant with urea resulted in significantly higher soil volumetric water content (in sandy loam and sandy clay loam soils) and higher bermudagrass clipping yield (in all soils) than urea. Surfactants applied with urea decreased percent 15N recovery in leachate from sand by 37–46%, increased percent 15N recovery in the sandy loam by 37%, and increased percent utilization of 15N by bermudagrass grown in the sandy clay loam by 61–67% compared to urea applied alone. Conclusion: Applying surfactants with urea can increase bermudagrass N uptake efficiency and reduce potential N leaching.

“…Several studies demonstrated that bermudagrass plants are quite tolerant of submersion, even for an extended period. Wherley et al (2011) studied the response to soil saturation over 72 days on plant development of two warm-season species: common centipedegrass [Eremochloa ophiuroides (Munro) Hack] and 'Tifway 419' hybrid bermudagrass [Cynodon dactylon (L.) Pers. × C. transvalensis Burtt Davy].…”

De Luca et al., 2008) including species choice. Due to climate changes, warm-season species, and especially bermudagrass, are becoming popular in the transition zones of Europe (Macolino et al., 2016). However, only a few studies have investigated the effect of increased rainfall intensity on early-stage growth of warm-season turf species. Heavy or total plant submersion, or waterlogging when plants are not submerged but soil pores are saturated (Bailey-Serres et al., 2012; Striker, 2012). Waterlogging and, to a greater extent, submersion, can cause several visible symptoms on plants, especially when they are prolonged, such as reduced photosynthetic activity, abscission of leaves, chlorosis, lower growth of roots and stems (Batzli and Dawson, 1997). Flooding events can be extremely harmful to plants (Bailey-Serres et al., 2012), a decrease in oxygen diffusion rate (ODR), pH, and soil redox potential, and an accumulation of toxic com-uration (Parent et al., 2008; Voesenek et al., 2006). The oxyof oxygen to plant roots that can restrict seedling emergence (Chesworth, 2008; Neira et al., 2015). Studies by Letey et al. (1966) found that at ODR of 0.15-2 cm-1 roots growth of bermudagrass (Cynodon spp.) drastically reduced, even if
