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...
Ammonia volatilization trends following liquid hog manure application to forage land
January 1, 1999By Brian D. Lambert
Recent changes in the livestock industry of western Canada have included the increased establishment of intensive hog operations in semiarid regions where the availability of cultivated land for...
Evaluating peats for their capacities to remove odorous compounds from liquid swine manure using headspace "solid-phase microextraction"
January 1, 1999
This paper reports on research designed to investigate the capacities of different highly characterized peats to remove odorous compounds from liquid swine manure (LSM). Peat types representing a...
Shallow subsurface drains to reduce nitrate losses from drained agricultural lands
January 1, 1999
Nitrate losses from subsurface drainage systems remain an important environmental concern. Data were collected from two drainage systems near Plymouth, North Carolina, to evaluate the effect of...
Nitrogen Recovery and Partitioning with Different Rates and Methods of Sidedressed Manure
January 1, 1999
Animal manure is an important source of N for crops in areas with intensive livestock production. Variable manure N availability can incite over-application of manure or supplemental fertilizer...
N-source effects on temporal distribution of NO3-N leaching losses to subsurface drainage water
January 1, 1999By R. S. Kanwar
Understanding the temporal distribution of NO3-N leaching losses from subsurface drained ?tile? fields as a function of climate and management practices can help develop strategies for its...
Phosphorus runoff from incorporated and surface-applied liquid swine manure and phosphorus fertilizer
January 1, 1999
Excessive fertilization with organic and/or inorganic P amendments to cropland increases the potential risk of P loss to surface waters. The objective of this study was to evaluate the effects of...
