| Abstract/Contents: | Water in some regions is scarce and it will continue to be scarce. Some regions have passed laws restricting water use for turf irrigation. Therefore, the turfgrass manager must learn how manage under drought conditions. Water conservation strategies for irrigated turf include: (1) species and cultivar selection, (2) environmental and cultural factors that influence shoot transpiration rate, (3) irrigation practices, (4) efficient and effective irrigation system, (5) water absorption capability of the root system. Cultural influences on evapotranspiration rate (ET) are (1) cutting height - shorter is better, (2) mowing frequency - less frequent is better, (3) Nitrogen nutrition - less is better, (4) irrigation - less is better, water when the plants begin to wilt, (5) use growth inhibitors. Irrigation practices; (1) don't exceed soil infiltration rate, (2) don't saturate the soil, reduce total amount of water, (3) water when ambient temperature is lowest - usually dawn, (4) water when winds are lowest - usually dawn. Insure an efficient, effective irrigation system; (1) obtain a reliable water source, (2) apply water uniformly, (2) install irrigation system to specification, (3) use zonal controls (4) repair leaks (5) replace worn parts. Factors to enhance drought hardiness; (1) moderate to low N, (2) adequate K, (3) low intensity irrigation, (4) full sunlight conditions. Maximize rainfall effectiveness by; (1) coring and slicing to improve infiltration, (2) on slopes, install vertical French drains, filled with pea gravel, (3) maximize water absorption by roots by selecting deep rooted species and cultivars (bermudagrass can root up to 8 feet deep). The soil environment factors that are favorable to deep rooting are: (1) soil temperatures of 50 to 60 deg F, (2) soil pH between 5.6 and 7.4, (3) adequate soil aeration, (4) no soil waterlogging, (5) no hydrophobic soils (apply wetting agent if necessary), (6) no saline or sodic soils (apply sodium or gypsum if necessary), (7) no insect, nematode or disease injury, (8) no toxic herbicides. Tables following the article rank turfgrasses by evapotranspiration rate, drought resistance, and rooting depth. |
