| Abstract/Contents: | "Dispersal of sewage effluent on golf courses is becoming widespread in the transition zone in the southeastern U.S. Effluent applications are leading to depressed bentgrass (Agrostis palustris Huds.) quality on putting greens. Early field reports indicate problems involve increased organic matter accumulation at the soil surface and water retention. In this study, we examine the chemical content of effluent irrigation ponds from three golf courses in North Carolina and, in controlled systems, begin to evaluate the likelihood of damage from salt toxicity and low oxygen in the root zone. Analyses of effluent samples over a 15 month period indicated mean conductivity levels of 0.45 to 0.58 dS m-1, much lower than that found in the western U.S., and the presence of substantial amounts of plant nutrients and carbon. Experiments in hydroponic culture indicated that conductivities of ~ 6 dS m-1were required to depress growth of a group of bentgrass cultivars. Simulating anaerobic conditions in hydroponics led to a distinct morphological adjustment by the bentgrass, with increased production of adventitious roots at the solution surface and decreased downward root growth. Aerenchyma tissues were observed in primary roots located in the lower anaerobic zone. The results indicate that bentgrass injury from salt toxicity is unlikely, except during periods of extended drought and high potential evapotranspiration (pET) which sometime occur in southeastern summers and could lead to salt accumulation at the soil surface. When anaerobic conditions occur, bentgrass susceptibility to salt and heat stresses will increase as the morphological adjustment concentrates roots near the soil surface." |
