Effects of chemical amendments on the gaseous emissions from swine manure
January 1, 1999
Control of emission of gases such as ammonia (NH3), hydrogen sulfide (H2S), carbon dioxide (CO2) and methane (CH4) is a major concern for large-scale swine producers. The use of chemical amendments...
Struvite precipitation in anaerobic swine lagoon liquid: effect of pH and Mg : P ratio and determination of rate constant
January 1, 1999By Nathan O. Nelson
Because of increased concern about surface water eutrophication from nutrient-enriched agricultural runoff, many swine producers are encouraged to decrease application rates of waste-based P....
Soil chemical and microbiological properties in hay production systems: residual effects of contrasting N fertilization of swine lagoon effluent versus ammonium nitrate
January 1, 1999
This study characterized soil chemical and microbiological properties in hay production systems that received from 0 to 600 kg plant-available N (PAN) ha(-1) year(-1) from either swine lagoon...
Optimization of liquid swine manure sidedress rate and method for grain corn
January 1, 1999By B. R. Ball-Coelho
Sidedressing may provide a better window of opportunity for land application of liquid swine (Sus scrofa) manure than early spring or fall application. Rates could be fine-tuned to match crop N...
Swine manure odor control by the TOAST (trademarked) aerobic system
January 1, 1999
A novel aerobic animal waste treatment system (Tertiary Oxygen Activated Sludge Treatment - TOAST trademark) was operated on an pig farm in southern Minnesota, USA. The fully operational system was...
A biomarker for the identification of swine fecal pollution in water, using the STII toxin gene from enterotoxigenic Escherichia coli
January 1, 1999
This research developed a PCR method to identify swine fecal pollution in water, using a portion of the STII toxin gene from enterotoxigenic Escherichia coli as the target sequence. This method...
Soil nitrogen and phosphorus availability for field-applied slurry from swine fed traditional and low-phytate corn
January 1, 1999By J. S. Paschold B. J. Wienhold
Swine (Sus scrofa) slurry contains nutrients essential for crop production but usually contains more P relative to N than is required by most crops, creating the potential for negative environmental...
Measurements of odour and hydrogen sulfide emissions from swine barns
January 1, 1999
Odour and hydrogen sulfide (H2S) emissions were measured on ten swine farms in southern Manitoba between May and October in 1999 and 2000. On each selected farm, air samples were taken from barn...
Determining odor emissions from manure surfaces using a wind tunnel
January 1, 1999
A wind tunnel was used to measure odour emissions from the surface of a liquid manure storage basin on 15 June 1999 in Minnesota, USA. The basin stored manure from a 1200 sow gestation/farrowing...
Solids and nutrient removal from flushed swine manure using polyacrylamides
January 1, 1999By Matias B. Vanotti
Most of the organic nutrients and reduced carbon (C) materials in liquid swine manure are contained in fine suspended particles that are not separated by available mechanical separators. Treatment...
