Odorous emissions and odor control in composting swine manure/sawdust mixes using continuous and intermittent aeration
January 1, 1998By David L. Elwell
Swine manure mixed with sawdust was composted in 205 L pilot-scale vessels. Four runs with a total of 22 vessel studies were made during 1998 and 1999. Composting was conducted, with either...

Soil infiltration and wetland microcosm treatment of liquid swine manure
January 1, 1998
Management systems are needed to minimize water quality concerns associated with liquid swine manure from large swine production facilities. Experiments were conducted to investigate the removal of...
Carbon dioxide and nitrous oxide emissions following fall and spring applications of pig slurry to an agricultural soil
January 1, 1998
In Quebec, Canada, most pig slurry is applied to agricultural soils in the spring and fall. A study was initiated to compare the impact of the contrasting spring and fall weather conditions on CO2...
Denitrification following land application of swine waste to bermudagrass pasture
January 1, 1998By D. G. Sullivan
Nitrogen (N) losses following land-applied animal wastes present an environmental and economical dilemma for producers. Gaseous N losses from pastureland contribute to global warming, ozone...
Odor and gas reduction from sprinkling soybean oil in a pig nursery
December 1, 1997
Daily sprinkling of very small amounts of vegetable (soyabean) oil inside a pig nursery facility reduced the odour, hydrogen sulfide (H2S), and total dust levels of the air inside the barn and in the...
Reduction of nutrients and odor in swine manure with sequencing batch treatment and intermittent aeration
August 1, 1997
A pilot plant with capacity to treat up to 1.5 msuperscript 3/day was installed in August 1997 at D & B Swine Farm in Halifax County, North Carolina, USA. The system was composed of a...
Biological Control of Hog Waste Odor through Stimulated Microbial Fe(III) Reduction
July 1, 1997By John D. Coates
Odor control and disposal of swine waste have inhibited expansion of swine production facilities throughout the United States. Swine waste odor is associated primarily with high concentrations of...
Minimizing Cost while Safely Composting Swine Mortality in Roofed and Unroofed Compost Systems – An Evaluation of Type and Amount of Amendments on the Compost Process
July 1, 1997By Steven Moeller
Proper disposal of carcasses occurring due to mortality in animal production is necessary for protection of the environment and prevention of the spread of disease organisms. Mortality disposal laws...
Upflow biological aerated filters for the treatment of flushed swine manure
May 1, 1997
A pilot plant with capacity to treat up to 8 m3/day of supernate from settled flushed swine wastes was monitored for 12 months. The main system is composed of two upflow aerated biofilters connected...
Soil carbon and nitrogen dynamics following application of pig slurry for the 19th consecutive year. I. Carbon dioxide fluxes and microbial biomass carbon
May 1, 1997
Agricultural soils often receive annual applications of manure for long periods. The objective of this study was to quantify the effects of 19 consecutive years of pig (Sus scrofa) slurry (PS)...
