AMES, Iowa – The design and layout of new practices currently being considered for water quality improvements of farmland drainage will be the focus of a workshop scheduled for Dec. 11 in Fort Dodge.

It will provide information essential for designing and planning new water quality practices such as bioreactors, controls structures, saturated buffers and wetlands. While the economic benefits of tiling are well recognized, there are also environmental impacts from drainage. These new technologies can be useful in minimizing negative environmental impacts.

The workshop also qualifies for Certified Crop Advisor credits. A sign-up sheet for the credits will be available on the day of the workshop. Completion certificates will be available after the workshop concludes for application towards Professional Development Hours or Continuing Education Credits.

Check-in begins at 8 a.m. with the morning session starting at 8:15 a.m. The morning session will focus on the review of drainage water quality practices addressing nutrient reduction in the upper Midwest, woodchip bioreactor sizing and layout, water table management with shallow tiles and installation of control structures. Matt Helmers, professor and extension agricultural engineering specialist at Iowa State, will discuss the sizing and layout of woodchip bioreactors. Kapil Arora, agricultural engineering specialist with ISU Extension and Outreach, will review the nutrient reduction practices.

Chris Hay, senior environmental scientist with the Iowa Soybean Association, will conclude the morning with information on managing drainage with control structures.

The afternoon session will begin with Dan Jaynes, research soil scientist with the National Laboratory for Agriculture and the Environment, USDA-ARS, discussing site selection and the design of saturated buffers. The event will close with Arora presenting on siting wetlands for small watersheds.

Register by contacting the ISU Extension and Outreach Webster County office at 515-576-2119 or; or by completing and mailing the registration form in workshop brochure. Registration is $150 and includes morning refreshments, lunch and workshop materials. Registration cost increases to $175 if done after Dec. 7.

Each participant should bring a laptop computer equipped with a USB drive. Microsoft Excel software used for designing select practices will be provided on a thumb drive. All laptops must have Excel pre-installed on them to run the spreadsheets and to perform design calculations. Use of laptops will be limited to practices using the spreadsheets for making design calculations.

The workshop is presented by ISU Extension and Outreach, the Iowa Soybean Association and the USDA Agricultural Research Service.
