Iowa Select Farms Announces Major Commitment to Odor Reduction

Iowa’s Largest Pork Producer Partners with the Coalition to Support Iowa’s Farmers

Iowa Select Farms recently announced a significant commitment to odor reduction and farm beautification. Moving forward, the company will install trees and an electrostatic fence on all new company-owned farms. Iowa Select Farms’ tree program will be carried out as part of the Coalition to Support Iowa’s Farmers’ Green Farmstead Partner Program.

Speaking about the fence and trees at an event announcing the partnership, Dr. Noel Williams, Chief Operations Officer for Iowa Select Farms said, “As much as I would like them to, they don’t help us grow better or more pigs. But, they are important. They help us be good neighbors and responsible members of our rural communities and state.”

The announcement coincided with a ribbon cutting and open house for Iowa Select Farms’ Hale Finisher. Located near Williams, the farm is the first of Iowa Selects’ to feature a mix of new and old odor reduction technologies. As a Green Farmstead Partner, the farm features three rows of trees and one row of shrubs-80 conifer arborvitae evergreen trees and 82 dogwood shrub bushes. Selected for their quality, hardiness, growth traits and ability to serve as an effective windbreak, the trees and shrubs will help reduce livestock odors coming out of the barns.

“I’d like to recognize Iowa Select Farms for going above and beyond what is required of them by visually demonstrating to their neighbors and community their commitment to doing things right by participating in the Green Farmstead Partner program,” said Brian Waddingham, Executive Director of the Coalition to Support Iowa’s Farmers. Through the Green Farmstead initiative, the Coalition helps farmers who are interested in planting windbreaks and aesthetic tree plantings on their livestock farms and connects them with participating landscapers.

Electrostatic Fence Adoption Further Reduces Odor

In addition to the Green Farmstead Partnership, Iowa Select Farms unveiled an electrostatic fence technology at the end of each new finishing barn. The technology was included in the plans after the company switched from a naturally ventilated, curtain-sided barn to a tunnel-ventilated finishing barn.

“Tunnel ventilated barns mechanically pulls the air through the barn and out the exhaust fans,” explains Dr. John Stinn, Environmental Project Manager for Iowa Select Farms. “Now, with air flowing out of barn at one location, odor reduction technologies such as fences, tree lines and other windbreaks can be significantly more effective.”

“Odor can attach itself to small dust particles that circulate inside the barns,” said Dr. Stinn. “What we’re really trying to do with the trees and the fence is to knock these particles down, which will in turn reduce transmission of odor. Our best chance to do this is when the particles leave the exhaust fans.”

When the dust particles enter the ionization field between the fans and the electrostatic fence, a negative charge is placed on the particles. When the particles hit the fence, it serves as a grounding plate which attracts and grabs the charged particles.

The fabric fence also slows the airspeed and mechanically filters the larger dust particles and which will be washed off by rain showers, or by a power-washer if necessary.

Stinn and his engineering team have partnered with Iowa State University to continue testing the technology to measure the results.

Stinn says the electrostatic fences can reduce odor transmission by 50-70 percent. Paired with the trees and scrub lines placed immediately behind the fence the combined effort to reduce odors experienced by neighbors to the farm should result in an even higher reduction rate.
