Evaluation of vegetative filter strips for swine lagoon wastewater
January 1, 1998By David T. Hill
Vegetative filter strips (VFS), on slopes of 5 and 11%, were used as a means of treating wastewater effluent from the second cell of a swine waste anaerobic lagoon system. Wastewater samples from...
An inflatable cover for a concrete manure storage in a swine facility
January 1, 1998
This study demonstrated that an air supported inflatable manure storage cover could be an economical and effective method for reducing odour emission into the atmosphere. To construct this inflatable...
Modeling ammonia volatilization from surface-applied swine effluent
January 1, 1998By D. L. Nofziger
Ammonia volatilization is an important issue in agricultural production and environmental protection. Experimental methods and numerical models exist to estimate the rate and amount of ammonia...
Odor and gas reduction from sprinkling soybean oil in a pig nursery
December 1, 1997
Daily sprinkling of very small amounts of vegetable (soyabean) oil inside a pig nursery facility reduced the odour, hydrogen sulfide (H2S), and total dust levels of the air inside the barn and in the...
Reduction of nutrients and odor in swine manure with sequencing batch treatment and intermittent aeration
August 1, 1997
A pilot plant with capacity to treat up to 1.5 msuperscript 3/day was installed in August 1997 at D & B Swine Farm in Halifax County, North Carolina, USA. The system was composed of a...
Biological Control of Hog Waste Odor through Stimulated Microbial Fe(III) Reduction
July 1, 1997By John D. Coates
Odor control and disposal of swine waste have inhibited expansion of swine production facilities throughout the United States. Swine waste odor is associated primarily with high concentrations of...
Minimizing Cost while Safely Composting Swine Mortality in Roofed and Unroofed Compost Systems – An Evaluation of Type and Amount of Amendments on the Compost Process
July 1, 1997By Steven Moeller
Proper disposal of carcasses occurring due to mortality in animal production is necessary for protection of the environment and prevention of the spread of disease organisms. Mortality disposal laws...
Upflow biological aerated filters for the treatment of flushed swine manure
May 1, 1997
A pilot plant with capacity to treat up to 8 m3/day of supernate from settled flushed swine wastes was monitored for 12 months. The main system is composed of two upflow aerated biofilters connected...
Soil carbon and nitrogen dynamics following application of pig slurry for the 19th consecutive year. I. Carbon dioxide fluxes and microbial biomass carbon
May 1, 1997
Agricultural soils often receive annual applications of manure for long periods. The objective of this study was to quantify the effects of 19 consecutive years of pig (Sus scrofa) slurry (PS)...
Release and Dispersion of Volatile Organic Compounds and Trace Gases From Swine Manure Systems in Iowa, Arkansas, and North Carolina
April 1, 1997By J.L. Hatfield
Release of gaseous compounds from swine manure storage systems has been poorly quantified; however, the perception of intensive amounts of gases is one of the larger problems for the pork industry....
