Research Project: Management and Bmp Assessment for Managed Turf

Location: Soil Drainage Research

2012 Annual Report


1a.Objectives (from AD-416):
Assess and characterize the environmental aspects of golf course turf, including the development and evaluation of management strategies or technologies to mitigate the potential offsite transport of sediment, nutrients, and pesticides. a) Quantify the fate and transport of nutrients, pesticides, and sediment from a managed turf watershed. b) Determine the processes and management controlling the fate and transport of sediment, nutrients and pesticides on golf course turf. c) Test novel BMPs and management strategies aimed to minimize nutrient, pesticide, and sediment export.


1b.Approach (from AD-416):
A field approach will be used to assess and characterize the environmental aspects of golf course turf, including the development and evaluation of management strategies and/or technologies. 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, pesticides, and sediment from turf environments. The reasearch site is located at Northland Country Club in Duluth, MN. Four different sites (two surface and two subsurface) are instrumented with automated sampling equipment. Treatments include an end-of-tile cartridge system as well as setbacks from surface inlets, and filter socks around surface inlets.


3.Progress Report:

Progress continues in quantifying the water quality impacts of managed turf at a golf course located in Duluth, MN. The surface and subsurface losses of nutrients, pesticides, and sediments continue to be measured. The findings suggest that phosphorus losses from managed turf systems may be significant and methodologies should be investigated to mitigate those losses. We are in the second year of a study to determine the impacts of placing filter socks around surface inlets to subsurface drains and reduced phosphorous (P) application on P transport. The preliminary results show promise in this technology and approach. The work and progress associated with this project support objective 1 parent project, specifically subobjective 1c: Assess and characterize the environmental aspects of urban and golf course turf.
