The first product from Agriliance LLC uses a soybean by-product as a main ingredient to help reduce hog manure odors. Called Barrier, the new odor mitigation aid is a liquid that is poured directly on top of stored manure to create a barrier that seals in gases.

The product was tested for three years in field trials and at Iowa State University, the University of Minnesota and North Carolina State University. Various types of hog facilities and ventilation systems were tested in different environmental conditions.

According to product manager Mark Schoenfeld, the university tests show that using the liquid on manure can reduce hydrogen sulfide by 75% and ammonia by 40%.

“In pits, once Barrier is poured over manure, it floats to the surface to reduce the amount of gases, and no agitation or stirring is necessary,” Schoenfeld says. It also may be added to manure in application equipment for field application.

The soybean by-product used in the product is acidulated vegetable oil, which is left over after refining for soy oil. The by-product also is used for high-energy animal feed.

“If we could get just 10% of the country's finishing facilities to use Barrier, we would need about 60 million bushels of soybeans to produce enough by-product to make Barrier,” Schoenfeld claims.

He says that another contributor to livestock odor is livestock dust particles, which attach to air molecules and are carried off to other areas.

One gallon of Barrier treats 2,000 gal. of stored manure. One application per month is suggested. Suggested retail price for a 2½-gal. jug is about $25. For more information, contact Agriliance, Dept. FIN, Box 64089, St. Paul, MN 55164, 651/451-5151 or circle 218.
