| Abstract/Contents: | "With greater emphasis on water conservation, turfgrass managers must reduce irrigation, yet continue to produce quality turf. Research has demonstrated that ET-replacement irrigation results in the development of soil water repellency, thereby adversely influencing conservative watering strategies. The objective of this study was to determine the effectiveness of different types and rates of surfactants on reduction of soil water repellency. An experimental and standard soil surfactant were evaluated from 1993 to 1994 in field trials with warm and cool season turfgrasses, and a range of climates and soils across the United States. ACA864 was evaluated at four rates (0, 63, 125 or 188 ml 100mā»Ā²) and compared to AquaGro (250 ml 100mā»Ā²). All treatments were applied monthly as liquids for three to six months per year, depending on growing season. Soil cores were collected monthly prior to treatment applications and dried for at least two weeks at room temperature. Water repellancy was measured at 1 cm intervals from air/thatch interface to a depth of 4-6 cm by placing 36-40 Ī¼l of water on the soil surface and measuring the water drop penetration time (WDPT). Data were analysed for statistical significance (Pā¤0.05) by automated general linear model procedures. Soil water repellency was generally confined to the upper 0-3 cm of the core profile and was greatest in those regions highest in organic matter content, regardless of climate, turfgrass or soil. Significant differences were observed by rate, surfactant type and depth. Reductions in WDPT occurred in the upper 0-4 cm of the profile. Depending on location, treatment with increasing rates of ACA864 reduced the WDPT between 25 and 90% over standard and control treatments during periods of low precipitation and high evaporative demand. Results show that ACA864 treatment reduced water repellency as measured by WDPT, and should minimise or prevent the development of localised dry spots." |
