| Abstract/Contents: | Some people view application of fertilizer and pesticides to landscape as major contributors to decline of water quality following land development. Little research has been conducted on the runoff water from suburban landscapes. Significant amounts of nutrients and pesticides have been found in farmland runoff. When farmland runoff traversed grasslands, nutrients and pesticides decreased. Such studies suggest that turf might improve runoff compared to farmland runoff. With land development, impervious surfaces such as streets, rooftops, and parking lots increased; runoff quantity increased and water quality decreased. The Landscape Management Research Center was established to investigate the effect of landscape and turf management activities on urban runoff and leachate. Turfed slopes were established on which pesticides and fertilizers could be applied. Slopes were established with either PA certified Kentucky bluegrass sod, or two seeding mixtures: either a high quality mixture of perennial turfgrass species, or a commercial "contractor's mix" containing a high percentage of annual ryegrass. Studies have focused on the hydrological characterization of the slopes. The irrigation system could deliver water at the rate of 6"/hour, which is comparable to a very rare storm. By comparison, a 3"/hour storm happens once every 125 years. No more than 5% of the water ever ran off of the sodded plots. In the sodded plots, from 8/86 thru 9/88, runoff flows rates from rain were too low to measure. A small quantity of runoff collected was sufficient for analysis. Seeded plots had higher peak flow rates and total runoff volumes. The 17 to 25 mm sod thatch resulted in greater infiltration and reduced runoff. Analyses of water samples for nitrogen, phosphorus, and potassium showed concentrations that did not exceed 10 ppm when sampled 2 days after application. Most samples contained less than 5 ppm. |
