Nitrate leaching as affected by liquid swine manure and cover cropping in sandy soil of southwestern Ontario
January 1, 1999By B. R. Ball-Coelho
To assess the risk that liquid swine manure (LSM) application posed to groundwater quality and determine how to manage excess nitrates, LSM pre-plant injected at 75% (LSMlow) and > 100% (LSMhigh) of...
Evaluation of Nutrient Availability from Swine Manure
January 1, 1999By Douglas Beegle
To utilize swine manure nitrogen (N) to meet the needs of crops and protect water quality it is
critical that we can confidently estimate the availability of the N. While total nutrient content of...
Odor emission from mixtures of ground swine carcass material and liquid swine waste
January 1, 1999By Chuck Clanton
Mixing ground swine carcasses with the manure waste stream is a new concept currently being researched as an alternative carcass-disposal method. A concern has been raised with this method regarding...
Removal of malodorous compounds from liquid swine manure by subsurface constructed wetlands in a greenhouse
January 1, 1999
Odour removal from liquid swine manure by subsurface flow constructed wetlands located in a greenhouse was quantified. The relationship between wetland treatments (planted vs. unplanted) and the...

Development of a prefabricated treatment plant for diluted pig wastewater
January 1, 1999By P. Y. Yang
In order to develop a prefabricated treatment and reuse plant for diluted pig wastewater, an entrapped-mixed-microbial-cell (EMMC) process was evaluated for its process performance and economic...
Swine manure storage covers for odor control
January 1, 1999By Chuck Clanton
Twenty-one, 750-L (200 gal) polyethylene tanks were filled with swine manure. Air samples were collected 24 and 48 h after each manure addition. The samples were tested for odor strength using a...
Daylong monitoring of odor and gas emissions from animal facilities
January 1, 1999
This paper presents daily emission data for odour, ammonia, and hydrogen sulfide from 7 animal facilities in Minnesota, USA. The data were collected at 2 h intervals over a 12 h period during the day...
Field evaluation of an indoor ozonation system for odor control
January 1, 1999By Kevin M. Keener
A commercial ozone generation system was evaluated in a tunnel ventilated, 1000 head, pig finishing building under full ventilation (80,000 c.f.m.). Ozone levels increased along the length of the...
Potential for reduction of odorous compounds in swine manure through diet modification
January 1, 1999
Recent public concern about air pollution from pork production units has prompted more research to develop methods to reduce and control odors. Masking agents, enzymes and bacterial preparations,...
Changes in soil attributes following low phosphorus swine slurry application to no-tillage sorghum
January 1, 1999By Brian J. Wienhold
Swine (Sus scrofa) slurry can serve as an excellent fertilizer source. Application at rates to meet crop N requirements can result in excess soil P due to low manure N/P ratios. Low phytate corn...
