The Fate of Turfgrass Nutrients and Plant Protection Chemicals in the Urban Environment

About this book

Recent policy decisions aimed at improving and safeguarding regional surface and subsurface water quality often result in activities at state and local levels to regulate the sale and/or use of many common lawn fertilizer and pesticide products. Clear, comprehensive distribution of the research data generated during the last decade on the environmental fate of fertilizer nutrients and plant protection chemicals in the urban environment is critical to enable informed decisions by our public officials. This book records the proceedings of a RISE-ACS co-sponsored workshop (October 12-13, 2005) designed to provide a forum for turf researchers and environmental scientists to present research and practical information addressing the realities of turfgrass risk/benefits and how appropriate maintenance practices performed on urban lawns can impact water quality.
