Effect of Nutrients and Pesticides Applied to Turf on the Quality of Runoff and Percolating Water

摘要

The objective of the investigation was to determine the effect that nutrients and pesticides applied to lawn-type turf had on the quality of runoff and leachate. The results indicate that dense, high quality turfgrass stands, regardless of establishment method, affect the overland flow process to such a degree that runoff is insignificant. The ability of this type of vegetative community to allow water to infiltrate and promote the matabolism of solutes suggests that it might even possess the ability to be used as a water quality treatment medium. Levels of management required to produce the turf quality necessary for positive water quality impacts have not been determined. It is assumed that many poor quality turfgrass areas are not recipients of sound professional management.
