Greenhouse gas emissions from stored liquid swine manure in a cold climate
January 1, 2000
Current global warming has been linked to increases in greenhouse gas (GHG) concentrations. Animal manure is an important source of anthropogenic GHG, mostly of methane (CH4) and nitrous oxide (N2O)....
High dietary copper improves odor characteristics of swine waste
January 1, 2000By J.W. Spears
We conducted two experiments to determine the effects of dietary copper concentration and source on odor characteristics of swine waste. In both experiments, 192 weanling gilts and barrows were...

The waste treatment system presented in this article is one of the alternative waste management systems that have been evaluated for swine farms in North Carolina. The treatment system was designed...
Denitrification in marsh-pond-marsh constructed wetlands treating swine wastewater at different loading rates
January 1, 2000
Denitrification in constructed wetlands can be very important in the treatment of swine lagoon effluent when land application areas are limited. The objectives of this investigation were to determine...
Biofilter media mixture ratio of wood chips and compost treating swine odors
January 1, 2000By K. A.|Nicolai|R. E. and Janni
Biofilter media mixtures were compared in 18 pilot-scale biofilters treating pit gases from a swine facility. The compost and wood chips mixtures ranged from 100% wood chips to a 50-50 blend in 10%...
Geotextile covers to reduce odor and gas emissions from swine manure storage ponds
January 1, 2000
Odor, hydrogen sulfide (H 2 S), ammonia (NH 3 ), and volatile organic compounds (VOC, GC/MS analytes) were measured between May and October 2000, and between April and October 2001 at sites...
