2011 Annual Report 1a.Objectives (from AD-416) The objective of this project is to investigate natural resource issues associated with managed turf landscapes and evaluate best management practices designed to address natural resource concerns. 1b.Approach (from AD-416) The approach will primarily be field oriented. We will use field sites in OH, MN, and TX to assess the fate and transport of nutrients and pesticides from managed turf. Before – after watershed scale studies will be used to quantify the fate and transport as well as aid in the determination of the processes and management controlling the fate and transport of nutrients and pesticides from turf environments. Additionally, we will investigate different best management practices and technologies including end-of-tile and in-stream filtration, buffers, application setbacks, organic fertilizers, and clippings removal. 3.Progress Report Positive progress continues to be made toward identifying and implementing best management practices. We are currently investigating the environmental impact of reduced fertilizer application and changes in formulation (inorganic to organic). As a portion of this study we have installed filter socks around all surface inlets within a sub-drainage area on the golf course in Minnesota. Water quantity and quality data continue to be collected and analyzed in support of this research question.
