Manure composition of swine as affected by dietary protein and cellulose concentrations
January 1, 2006
An experiment was conducted to investigate the effects of reducing, dietary CP and increasing dietary cellulose concentrations on manure DM, C, N, S, VFA, indole, and phenol concentrations....
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

Aerating grassland before manure application reduces runoff nutrient loads in a high rainfall environment
January 1, 2006By Agriculture and Agri-Food Canada|Pacific Agri-Food Research Centre|S. Bittman
The effect of mechanically aerating grassland before liquid manure application in the fall on surface runoff and transport of nutrients and solids was studied in a high rainfall area. The two...
Piggery slurry composting using batch operating autothermal thermophilic aerobic digestion system
January 1, 2006
The performance of an autothermal thermopholic aerobic digestion (ATAD) system was studied to determine if nitrogen loss, as ammonia, was affected by an exhaust gas condenser. The system was run with...
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...
Modification and Validation of GLEAMS for Prediction of Phosphorus Leaching in Waste-Amended Soils
January 1, 2006By R.D. Kinley
Excess phosphorus applied to soils with low P adsorption capacities can enter surface water via leaching and subsurface transport, thereby negatively impacting water quality. Computer simulation...
Development of a hydrophilic interaction chromatography-mass spectrometry assay for spectinomycin and lincomycin in liquid hog manure supernatant and run-off from cropland
January 1, 2006
A specific and sensitive analytical method was developed to extract and quantify spectinomycin and lincomycin in liquid hog manure supernatant and simulated rainfall run-off from manure-treated...
