Research Project: Quantifying the Water Quality Benefits of Integrated/Stacked Conservation Practices

Location: Soil Drainage Research

Project Number: 5080-13210-003-009-I
Project Type: Interagency Reimbursable Agreement

Start Date: Mar 1, 2020
End Date: Sep 30, 2024

The goal of the project is to understand the water quality impacts of integrating practices in tile-drained cropland. The objectives are to (1) implement practice integration on farm fields; (2) measure discharge and water quality at edge-of-field, (3) analyze data to assess water quality impacts of the integrated practices; (4) scale up the potential for water quality improvements from practice integration through watershed modeling.

Implement practice integration on farm fields. Four farm field sites from the existing USDA-ARS edge-of-field research program will be used for this study. Site 1 in Delaware County, Ohio, will have a treatment of woodchip bioreactor and phosphorus filter. Site 2 is Defiance County, Ohio, will also have a combination of bioreactor and phosphorus filter. Site 3 is in Defiance County, Ohio, and will continue to have a combination of vegetated furrow ditches and a two-stage ditch. Site 4 is in Mercer County, Ohio, and will have a phosphorus filter and constructed wetland.
