| Abstract/Contents: | The third part of a series of publications examining sprinkler and subground irrigation systems. Presents results of a field study conducted at Hohenheim University. The objective of the study was to compare an underground irrigation and drainage system with a sprinkler irrigation system. Although a subground irrigation system was expected to reduce water usage, the actual response of typical turfgrasses to increases or decreases in the water supply was unknown; thus, the actual amount of water conserved was also unknown. Field trials were conducted to compare the effects of two different irrigation systems (sprinkler and subground) on water use, drought tolerance, and recuperative ability of three turfgrass species (Agrostis stolonifera 'Penncross', Festuca rubra trichophylla 'Barcrown', and Poa supina 'Supra'). To calculate turfgrass water use, the water content variation of the top 10cm of the rootzone mix was measured. Drought tolerance was quantified by calculating the Crop Water Stress Index (CWSI) from leaf surface temperatures measured with a hand held infrared thermometer. Visual quality of the turf was assessed by ranking, and irrigation water use was also measured. The two-year field study yielded the following results: The temperature distribution in the underground irrigated plots proved more homogenous than the sprinkler irrigated ones. This indicates that a more uniform water distribution can be achieved with the Cellsystem (underground system) than the sprinkler system. The irrigation method had a significant effect on soil water content in the upper 10cm of the rootzone mix. During two of the three drought periods, the water content in the topmost layer of the soil was significantly higher in the Cellsystem plots (under both permanently adjusted and changing water tables) than in the sprinkler-irrigated plots for each of the tested turf species. The consistently higher water content of the topmost 10cm of the Cellsystem plots during two of the three drought periods led to lower stress ratings in the examined grass types. Thus, the irrigation method significantly influenced the CWSI's of the grasses. Even when the soil water content in the Cellsystem plots dropped below that of the sprinkler-irrigation plots (third drought period), the CWSI ratings of the Cellsystem plots at the end of the drought period remained significantly lower than on the sprinkler-irrigated plots. The "general impression" of the turf was unaffected by irrigation type throughout all research periods. The recuperative ability after the drought periods could be estimated by the turf quality ratings; this resulted in no significant difference in recuperative ability based on irrigation method. Of the grass species researched, Festuca rubra trichophylla showed the best drought tolerance, followed by Agrostis stolonifera. Due to slow drought response mechanisms (significantly lower root masses in the 20 to 30 cm soil depths than the other species), Poa supina exhibited the lowest drought stress tolerance. The overall water use differed quite significantly between the two irrigation systems during the two year research period. Cellsystem used 55mm in the first year and 74mm in the second year. During the same time periods the sprinkler irrigation system required 532mm and 1163mm, respectively. At the end of the drought periods, the significantly lower CWSI ratings of the Cellsystem plots indicated a better water supply status for the grass types examined in comparison to the sprinkler irrigated plots. This was attributed to the more extensive root system in the Cellsystem irrigated turf which enabled better water uptake in soil depths greater than 10cm. It is evident that the Cellsystem subground irrigation is a practical water-saving alternative to the traditional sprinkler systems used on common turfgrasses. |
