| Abstract/Contents: | "There is concern about the applicability of results obtained from small-plot turf investigations to larger turf areas such as a golf course fairway. A runoff facility was constructed at the University of Maryland to examine the effect of plot size on pesticide fertilizer runoff. Chemical runoff was examined during a single high-intensity rainfall event that took place one day after applying a three-product pesticide tank mix and granular forms of N and P. The study's findings include: Plot size had no effect on the runoff of foliar applied pesticides or on urea total N losses. Greater P runoff from the large size plots was attributed to mass transport of triple superphosphate granules in large streams of runoff that developed within the these plots during the rainstorm event. The high chemical runoff losses observed in this study were the result of wet soil conditions, not watering granular products in after application, and the short time interval between the application of the chemicals and the rain storm event. Scheduling chemical applications around weather conditions that favor near-term runoff generating storm events is one of the most powerful management tools superintendents have at their disposal to minimize chemical transport to surface waters." |
