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
Dietary manipulation of sulfur for reduced H2S emission from swine waste
This experiment was conducted to evaluate H2S production rates from nursery pig swine manure stored in simulated waste storage pits as influenced by sulfur content of the diets fed. Waste from six...
Single-component modelling of pig farm odour with statistical methods and neural networks
Pork farm odour has become an increasingly important problem for the pork industry because non-farming rural residents object to the odours coming from pig facilities and insist that it disrupts...
Antimicrobial residues in animal waste and water resources proximal to large-scale swine and poultry feeding operations
Expansion and intensification of large-scale animal feeding operations (AFOs) in the United States has resulted in concern about environmental contamination and its potential public health impacts....
Separation distances for swine odor control in relation to manure nutrient balances
One approach to odor abatement at swine facilities is to provide adequate buffer zone or separation distance from neighbors. Use of a nutrient (nitrogen and phosphorus) balance to determine land...
Rates and controls on denitrification in an agricultural soil fertilized with liquid lagoonal swine waste
Under laboratory conditions, we studied rates and controls on denitrification and denitrification potential (denitrifying enzyme activity, DEA) in agricultural soils in the southeastern United States...
Odorous emissions and odor control in composting swine manure/sawdust mixes using continuous and intermittent aeration
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
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
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...
