Modeling sources of gaseous emissions in a pig house with recharge pit
January 1, 2006By Peter Kai
Ammonia, methane, and odor from a fully slatted pig housing facility equipped with a pit-recharge manure system were modeled with a view to quantify the sources of ammonia, methane, and odor...
Review of the use of aerobic thermophilic bioprocesses for the treatment of swine waste
January 1, 2006By Pierre Juteau
For 40 years, aerobic thermophilic (AT) processes have been presented as a possible way of treating liquid manure, especially swine wastes. If they are well designed, bioreactors can be self-heating...
Using stream bioassessment protocols to monitor impacts of a confined swine operation
January 1, 2006
The processing of waste from confined animal feeding operations (CAFOs) presents a major environmental challenge. Treatment of waste and subsequent land application is a common best management...
Source-Related Transport of Phosphorus in Surface Runoff
January 1, 2006By F. Shigaki
Continual application of mineral fertilizer and manures to meet crop production goals has resulted in the buildup of soil P concentrations in many areas. A rainfall simulation study was conducted to...
Disinfection of swine wastewater using chlorine, ultraviolet light and ozone
January 1, 2006By Macauley
Veterinary antibiotics are widely used at concentrated animal feeding operations (CAFOs)
to prevent disease and promote growth of livestock. However, the majority of antibiotics
are excreted from...

Free fatty acids and sterols in swine manure
January 1, 2006By Loughrin
Free fatty acids and sterols were assessed in fresh manure and anaerobic lagoon sludge from swine production facilities in North Carolina. Eight free fatty acids and five sterols were identified and...
Soil Nutrient Dynamics from Swine Effluent Application to Common Bermudagrass Overseeded with Cool-Season Annuals
January 1, 2006By K. R. Sistani
A 3-year study was conducted to investigate the major nutrient dynamics in soil receiving swine effluent as the sole source of plant nutrients for warm-season perennial bermudagrass and cool-season...
Effects of cropping systems on NO3-N losses to tile drain
January 1, 2006By Kanwar
ABSTRACT: Diverse cropping systems can have significant impacts on nutrient losses through tile drain systems and to surface water bodies (rivers and streams). Increased transport
of nitrogen to...
Alum Settling and Filtration Treatment of Liquid Swine Manure
January 1, 2006By Mohamed Gamal El-Din
A physical/chemical treatment train, which involved preliminary settling for 24 h followed by coagulation/flocculation of supernatant, and filtration, was applied to raw flushed swine manure in...
Influence of tillage and liquid swine manure on productivity of a soybean-barley rotation and some properties of a fine sandy loam in Prince Edward Island
January 1, 2006By Carter MR
Interactions between tillage management for manure incorporation and rate of manure application may influence crop productivity and soil properties. This study was conducted to evaluate the effect of...
Ammonia recovery from swine belt separated liquid
January 1, 2006By Sarah K. Liehr
An evaluation of the feasibility of ammonia stripping for ammonia recovery from waste liquid resulting from an in-house belt separation system is presented. The liquid stream produced is a ...
Factors Influencing Illinois Farmland Values
January 1, 2006By Haixiao Huang
A hedonic model of Illinois farmland values is estimated using county-level cross-section time-series
data. Explanatory variables include land productivity, parcel size, improvements, distances to...
