Tylosin sorption to silty clay loam soils, swine manure, and sand
January 1, 2005
The objectives of this study were to assess sorption and desorption of tylosin, a macrolide antimicrobial chemical used in swine, cattle, and poultry production, in three silty clay loam soils of...
Movement of lagoon-liquor constituents below four animal-waste lagoons
January 1, 2005By Gary M. Pierzynski
Movement of liquor constituents from animal-waste lagoons has the potential to degrade ground water quality. The depth of movement and concentrations of lagoon-liquor constituents in the soil...
Environmental assessment tools for the evaluation and improvement of European livestock production systems
January 1, 2005
Different types of assessment tools have been developed in Europe with the purpose of determining the environmental impact of various livestock production systems at farm level. The assessment tools...
Removal of pathogen and indicator microorganisms from liquid swine manure in multi-step biological and chemical treatment
January 1, 2005By Matias B. Vanotti
Concern has greatly increased about the potential for contamination of water, food, and air by pathogens present in manure. We evaluated pathogen reduction in liquid swine manure in a multi-stage...
Knowledge-based fuzzy control of pilot-scale SBR for wastewater treatment
January 1, 2005By Myung-Geun Chun
A fuzzy controller to optimize oxic phase of sub-cycle in pilot scale SBR (working volume, 20m(3)) located at public swine wastewater treatment plant was investigated. The operation mode of...
Extractable Soil Phosphorus and Inorganic Nitrogen following Application of Raw and Anaerobically Digested Swine Manure
January 1, 2005
Processing of swine (Sus scrofa domestica) manure in an anaerobic digester for biogas production is not a complete waste treatment process. Therefore, digested manure must be utilized in some manner,...
Infectious swine hepatitis E virus is present in pig manure storage facilities on United States farms, but evidence of water contamination is lacking
January 1, 2005By P. G. Halbur
Fresh feces, manure slurry (from earthen lagoons and/or concrete pits), and drinking and surface water samples were collected from 28 pig farms in the Midwestern United States. All samples were...
Sorption and desorption of ammonium from liquid swine waste in soils
January 1, 2005By K. Xia
Understanding the sorption and desorption behavior of NH4(+) in soils associated with animal waste is important because of the potential for the formation of NO3(-) and subsequent leaching that...
Multidimensional gas chromatography-olfactometry for the identification and prioritization of malodors from confined animal feeding operations
January 1, 2005By Donald W. Wright
Odor profiling efforts were directed at applying to high-density livestock operations some of the lessons learned in resolving past, highly diverse, odor-focused investigations in the consumer...
Soil extractable phosphorus changes with time after application of fertilizer: II. Manure from swine fed modified diets
January 1, 2005
Little is known about how diet modification and manure amendments affect extractable P in soils, which can be related to runoff P. The objectives of this study were to determine if there were any...
