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...
Crop nitrogen and phosphorus utilization following application of slurry from swine fed traditional or low phytate corn diets
January 1, 1999By B.J. Wienhold|J.S. Paschold
Field application of swine (Sus scrofa) slurry provides essential nutrients for crop production. The N to P ratio for slurry is lower than needed by most crops resulting in P accumulation when...
Ammonia volatization from liquid hog manure amended with paper products in the laboratory
January 1, 1999
Losses of N from livestock operations due to ammonia (NH3) volatilization from animal wastes is a major source of pollution in Europe and North America, and represents a significant economic loss....
Continuous measurement of hydrogen sulfide emission from two large swine finishing buildings
January 1, 1999
The emission of hydrogen sulfide (H2S) was continuously measured from two 1,000-head growing-finishing pig buildings for 6 months during 2 partial growth cycles. Hydrogen sulfide concentration was...
Mass transfer coefficient of ammonia in liquid swine manure and aqueous solutions
January 1, 1999By J. Arogo
Correlations for the overall mass transfer coefficient of ammonia with liquid properties and environmental conditions were developed for ammonia volatilizing from aqueous solutions as well as from...
Atmospheric Concentrations, Transport, and Deposition of Ammonia/Ammonium from Large-Scale Swine Production Facilities
January 1, 1999By Dr. Wayne P. Robarge
Domestic animals are the largest global source of atmospheric ammonia (NH3), with emission rates ranging from 20-35 Tg N yr-1, approximately 40% of natural and anthropogenic emissions combined. (One...
The use of ozone to reduce the concentration of malodorous metabolites in swine manure slurry
January 1, 1999By Jerry J. Wu
A pilot-scale ozonation system was constructed and operated to reduce the malodours emanating from fresh and stored swine manure slurry. The concentrations of the malodorous bacterial metabolites...
Effect of a manure additive on the reduction of ammonia emission from large swine finishing buildings
January 1, 1999
The effect of Alliance, a manure additive, on air quality was tested in four commercial grow-finish swine buildings over a period of six months. The test was conducted in two treated and two control...
