Abstract/Contents:"Joint greenhouse and field studies are being carried out to evaluate selected plant species for their effectiveness in removing pesticides and nutrients from golf course turfgrass runoff waters that enter the rhizospheres of plants in vegetative filter strips (VFS). Eleven plant species (prairie cord grass, big blue stem, switchgrass, woolgrass, eastern gama grass, perennial rye, tall fescue, blue flag iris, black willow, sedge, cutgrass) and an unvegetated control have been evaluated in a greenhouse pot study to determine which species most effectively remove six pesticides (2 insecticides: chlorpyrifos, imidacloprid; 2 herbacides: pendimethalin, 2,4-D; and 2 fungicides: chlorothalonil, propiconazole) from contaminated soils (silt loam). Five species (blue flag iris, woolgrass, prairie cord grass, big blue stem and eastern gama grass) were determined to be most effective. A runon plot, consisting of 12 vegitative filter strips (VFS, 4.6m x 0.9m x 1.8m) has been established at the UMASS Turfgrass Research Center, South Deerfield, MA. Native soil at the site (sandy loam) was used in the construction and silt loam was brought in for the surface horizion (0-15cm). All plots had a 5% slope and each was lined with an impermeable 36-mil polypropylene liner. At the end of each VFS, an aluminum collection device was inserted underneath 7.6 cm of soildfor the last 30.5 cm of the strip to collect runoff water. An aluminum gutter, with holes drilled at 5.1 cm intervals was placed on the front (top) edge of each VFS to evenly apply runon water. Stainless steel lysimeters (Soil Measurement System, LLC) were placed 1.5 m below the soil surface and 4.3 m from the front (top) end of each strip. Several storm/runon scenarios using an rainfall equivalent to the average 1 year rain event were evaluated. A storm scenario was selected that produced runoff that was 1) measurable, 2) manageable, 3) roughly equivalent to those used by Bell and Moss (2005) for runoff experiments conducted using roughs cut to 3 heights. A bromide tracer study was carried out in the summer of 2007 using this storm scenario to determine any hydraulic differences between VFS prior to planting. VFS were then established in replicates of three (unvegetated, random mixture of plant species, succession of plant species (short to tall), and turfgrass cut to three heights (short to tall)."
