Abstract

Odor and gaseous emissions from the swine industry are of concern for the wellbeing of humans and livestock. Additives applied to the swine manure surface are popular, marketed products to solve this problem and relatively inexpensive and easy for farmers to use. There is no scientific data evaluating the effectiveness of many of these products. We evaluated 12 manure additive products that are currently being marketed on their effectiveness in mitigating odor and gaseous emissions from swine manure. We used a pilot-scale system simulating the storage of swine manure with a controlled ventilation of headspace and periodic addition of manure. This dataset contains measured concentrations and estimated emissions of target gases in manure headspace above treated and untreated swine manure. These include ammonia (NH3), hydrogen sulfide (H2S), greenhouse gases (CO2, CH4, and N2O), volatile organic compounds (VOC), and odor. The experiment to test each manure additive product lasted for two months; the measurements of NH3 and H2S were completed twice a week; others were conducted weekly. The manure for each test was collected from three different farms in central Iowa to provide the necessary variety in stored swine manure properties. This dataset is useful for further analyses of gaseous emissions from swine manure under simulated storage conditions and for performance comparison of marketed products for the mitigation of gaseous emissions. Ultimately, swine farmers, the regulatory community, and the public need to have scientific data informing decisions about the usefulness of manure additives.

Highlights

The deep pit under the slatted floor often stores manure for a year, which is applied as a fertilizer on the fields
This dataset is in a spreadsheet format, which includes NH3, hydrogen sulfide (H2 S), volatile organic compounds (VOC), and GHG emissions from untreated swine manure and swine manure treated with manure additives for two months
In the spreadsheet pertaining to NH3 and H2 S, both concentrations are given in ppm

Summary

The United States is one of the top three pork-producing countries, and Iowa is the biggest pork-producing state. The deep pit under the slatted floor often stores manure for a year, which is applied as a fertilizer on the fields (in the fall after harvest) This commodity generates profits profits and forcommunities, local communities, generates chemical gases thatthe affect the air and jobs forjobs local but alsobut generates odorousodorous chemical gases that affect air quality quality in the surrounding communities.
