Research Project: Natural Resource Issues in Turfgrass Environments

Location: Soil Drainage Research

2012 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 installed filter socks around all surface inlets within a sub-drainage area on the golf course in Minnesota and monitored the results. Chlorothalonil, a golf course fungicide was found to be transported frequently in golf course drainage waters. Water quantity and quality data continue to be collected and analyzed in support of these research questions. All investigations planned for the Texas location have now been completed and the research infrastructure has been removed from that location. The work and progress associated with this project supports objective 1 of the parent project, specifically sub-objective 1c: Assess and characterize the environmental aspects of urban and golf course turf.
