| Abstract/Contents: | "Irrigating turfgrass with recycled wastewater (RW) is becoming a common practice throughout many parts of the U.S. Most research on how RW affects soil and turfgrass quality has been conducted in hot-arid climates with little known about the affects in a cool-humid climate that typically receives substantial precipitation and only moderate periods of drought. This study looked at the impact on two cool season turfgrasses and three soils of irrigating exclusively with two concentrations (1X and 2X) of simulated wastewater with electrical conductivities (EC) of 0.82 and 1.64 dS m-1 respectively compared to normal irrigation water without a leaching fraction during simulated drought conditions. Creeping bentgrass (Agrostis stolonifera L.) (CB) and Kentucky bluegrass (Poa pratensis L.) (KB) were grown on sand, sandy-loam, and silt-loam soils under three different irrigation treatments while rainfall was excluded using a rainout shelter for three summer irrigations. Monthly turfgrass quality data, periodic soil electrical conductivity (EC) measurements, and soil infiltration rates were taken to assess the impact on soil and turfgrass health. A substantial decrease in turfgrass quality was seen during the second year of the study under a five month simulated drought period. Both turfgrasses reached unacceptable turfgrass quality ratings under the 2X irrigation treatment. Both RW treatments (1X and 2X) produced significantly poorer, but acceptable turf quality than the control irrigation water over the study for all soil types. Electrical conductivity measurements of the soil reached their highest levels in 2006, which correlated with the poorest turf quality levels. Creeping bentgrass accumulated significantly more salts in the surface soil layer than KB and exhibited turf damage in 2006 on the sand soil that did not fully recover before the 2007 drought simulation. Quality of CB was reduced to an unacceptable level when the average EC of the soil reached 6 dS m-1 while KB quality was unacceptable at 4 dS m-1. The use of recycled wastewater can have the ability to reduce turf quality to unacceptable levels in the Northeast of the U.S. under prolonged drought periods, if leaching fractions to flush salts accumulated in the rootzone are not implemented." |
