Brief Summary of Minutes of Annual Meeting

Brief Summary of the Annual Meeting

• The annual meeting was held jointly with the Conservation Drainage Network.
• The meeting had a total of 120 registered attendees, with 80 in-person and 40 online with participation from 14 states, three Canadian provinces and two European countries.
• The theme was “Advancing Implementation”, and the meeting focused on topics related to raising awareness, policy opportunities, and social science research that could address motivation barriers to adoption of conservation drainage practices.
• Speakers included USDA Under Secretary Robert Bonnie discussing how USDA is addressing implementation opportunities. Callie Eideberg, Senior Staff Lead of the US Senate Agriculture, Nutrition and Forestry Committee, and Josh Maxwell, Policy Director, US House Agriculture Committee, discussed the Farm Bill process and opportunities related to conservation
• State reports were provided by eight states. The reports highlighted drainage research and outreach activities in the states.
• During the advisor’s report, Ramesh Kanwar encouraged the group to continue multi-state collaboration. The current NCERA217 project expires in 2024 and a renewal writing committee was appointed.
• A summary of the annual meeting is at conservationdrainage.net/meetings-and-events/2023-conservation-drainage-network-annual-meeting/

Accomplishments: Nitrogen (N) and phosphorus (P) pollution of surface water from nonpoint sources is a serious problem nationwide. The water quality issues are exacerbated through surface and subsurface drains. The NCERA-217 group is documenting the impacts of conservation drainage practices which maintains the benefits of drainage while minimizing negative environmental impacts.

An example of newer drainage research is work in Oregon on the efficiency of a woodchip bioreactor to remove nitrate in water from tile drainage under a dairy operation and investigating carbon storage dynamics and greenhouse gas emission from fields with varying ages of tile drainage.

Another example is in Virginia, where the first large scale spring denitrifying bioreactor designed to remove legacy nitrogen (N) from emerging groundwater is being evaluated. Results from this site is used in the proposal for Virginia to claim N reduction for TMDL crediting under the Chesapeake Bay ditch bioreactor BMP protocol, and bioreactors are now part of the Virginia Phase III Watershed Implementation Plan (WIP) to treat legacy nutrients in emergent groundwater.

Short-term Outcomes: The 24 peer-reviewed journal articles, 11 other publications, 13 poster presentations, and over 45 other outreach activities and presentations produced during the reporting period are listed in the separate publications document. Additional outputs are listed below.

Outputs:

Extension Bulletins:

We completed tutorials for several online tools from the $5M USDA-funded Transforming Drainage project, https://transformingdrainage.org/tools/. The tutorials enable more people to use these tools to access geographic information and model simulations of likely benefits of innovative drainage practices.

As an example of the value and reach of extension materials produced by NCERA-217 members, Michigan State University had ten drainage-related Extension bulletins available in 2022 (available at www.egr.msu.edu/bae/water/drainage/). The publications had 611 downloads from June 2021 to September 7, 2022. That website had 25,496 page views from January 1, 2021 to September 8, 2022. The website was visited from over 20 countries in order of highest to lowest including the USA, United Kingdom, India, Canada, China, Australia, South Africa, and others.

Videos:

Seven professionally produced peer-reviewed videos were published:

• Four providing an overview of the process of designing and implementing drainage water recycling, https://transformingdrainage.org/videos/drainage-water-recycling/
  1. Drainage Water Recycling: Capturing, Storing, and Using Drained Water for Multiple Benefits (ABE-168-WV)
  2. Planning Drainage Water Recycling Systems (ABE-169-WV)
  3. Constructing Drainage Water Recycling Systems (ABE-170-WV)
  4. Managing Drainage Water Recycling Systems (ABE-171-WV)
• Three “spotlight” videos focusing on individual sites where drainage water recycling has been implemented, https://transformingdrainage.org/videos/dwr-spotlights/

1. Drainage Water Recycling Spotlight: Addressing an Outlet Challenge in Michigan (ABE-172-W)
2. Drainage Water Recycling Spotlight: Meeting Crop Needs in Minnesota (ABE-173-W)

Drainage Water Recycling Spotlight: Partnerships in Missouri  (ABE-174-W)

Tools:

Michigan State University has ten drainage decision-support tools available. The tools have already attracted more than 6,624 page views from May 1, 2021 to September 8, 2022. Number of users from highest to lowest were from Michigan, Ohio, Iowa, Minnesota, Illinois, Indiana, Wisconsin, Missouri, Nebraska, South Dakota, North Dakota, and other states.

Activities:

• Work studying the impacts of 4R N management on crop yield, soil health, nutrient losses with water, and gaseous emissions is being conducted across seven sites in the Upper Midwest US cornbelt and one site in Ontario, CA. This work has documented that use of 4R practices reduces nitrate-N loss with leaching and nitrous oxide loss. Additional work on the impacts of cover crops including perennial ground cover on drainage water quality and crop yield and impacts of drainage water recycling on crop yield is underway at Iowa State University.
• Virginia developed a peer reviewed extension article entitled: What to Consider When Considering an Agricultural Drainage System (BSE-208).
• NCERA217 collaborators confirmed the performance of a world-first, three-bed bioreactor designed to remove nitrate from large areas rather than single fields. As a conservative estimate, implementing watershed-scale bioreactors would reduce nitrate loads in the MRB states of Iowa, Illinois, and Minnesota by an additional 10,000 tons N/year (1.4% of annual N load) while reducing the number of installations by 90%.
