Upcoming Events: July 23

July 16, 2015

Iowa Learning Farms, along with the Monroe County Soil and Water Conservation District and Iowa Soybean Association, will host a field day on Thursday, July 23, from 10 a.m. to noon at the Tom Dykstra farm, rural Eddyville.

Linda Shumate, Monroe County watershed coordinator, is working with farmer Tom Dykstra to receive cost-share funding to install a denitrification bioreactor on his land. Shumate and Dykstra will share their experience and answer questions about installing the bioreactor. Dykstra has been farming full-time for 10 years, raising corn and soybeans as well as grazing his cattle herd. He uses no-till and cover crops including radishes, turnips, winter rye and winter wheat.

Keegan Kult, Iowa Soybean Association environmental programs manager, will talk about the water quality benefits of a bioreactor and research results from their bioreactors installed across the state. Iowa State University Extension and Outreach water quality engineer Matt Helmers will demonstrate the Conservation Station’s rainfall simulator, which shows the effects of rainfall on different surfaces and subsurface drainage including conventional tillage, no-till and cover crops. Following the field day, attendees can enjoy a complimentary lunch.

The field day will be at the Tom Dykstra farm: 1383 735th Ave., Eddyville. Take exit 53 off of Highway 63, just south of Eddyville. Go west on Highway 137, crossing the Des Moines River; turn south on Monroe Wapello Road (T59) just past the river. Go three miles, turn west onto 140th St., and go one mile. Turn north onto 735th St. for approximately a quarter-mile. The field day site will be on the west side of the road.

The field day is free and open to the public, but a RSVP is recommended. Contact Iowa Learning Farms by July 16 for a meal count: phone (515) 294-8912, or email [email protected].

As part of the Iowa Nutrient Reduction Strategy, cover crops added to a corn-soybean rotation reduces soil erosion, reduces nitrogen and phosphorus loads, and increases soil organic matter. Research has shown that cover crops can reduce nitrogen and phosphorus losses by approximately 30 percent. A bioreactor, one of the recommended edge-of-field practices, can reduce nitrogen by approximately 40 percent. These best management practices will reduce point and nonpoint source pollution significantly in Iowa waters and downstream.
