Residual effects of composted and fresh solid swine (Sus scrofa L.) manure on soybean [Glycine max (L.) Merr.] growth and yield
January 1, 2000By G.M. McAndrews|M. Liebman
Applying livestock manure to soil can enhance soil fertility and crop growth; however, little information is available on the residual effects of manure on crop growth. The objective of this study...
Design and analysis of a pilot scale biofiltration system for odorous air
January 1, 2000By John J. Classen
Three pilot-scale biofilters and necessary peripheral equipment were built to clean odorous air from the pit of a swine gestation building at North Carolina State University. A computer measured...
Laboratory measurement of hydrogen sulfide and sulfur dioxide releases from swine manure of different solid contents
January 1, 2000
Releases rates of Hydrogen sulfide (H2S) and sulfur dioxide (SO2) from finishing swine manure of two different solid contents and two initial manure accumulation days were measured under laboratory...
Swine effluent application timing and rate affect nitrogen use efficiency in common bermudagrass
January 1, 2000By Read J. J.
Bermudagrass (Cynodon dactylon (L.) Pets.] hay production is integral to manure management on southeastern swine farms. But swine effluent timing must be synchronized with crop nitrogen (N) demands...
Phototrophic anaerobic lagoons as affected by copper and zinc in swine diets
January 1, 2000By J. E. Gilley
Odor emissions from anaerobic lagoons containing large populations of phototrophic bacteria are usually minimal. This study was conducted to determine whether copper (123 ppm) and zinc (2,310 ppm) in...
A field study on downwind odor transport from swine facilities
January 1, 2000
From the eight swine facilities studied [locations not given], power functions were found to be an appropriate description of the pattern of downwind odour transport for both swine buildings and...
Effect of a manure additive on ammonia emission from swine finishing buildings
January 1, 2000
The effect of a commercial manure additive (Alliance) on ammonia (NH3) emissions was evaluated in commercial 1000-head grow-finish swine buildings over a six-month period. The test was conducted in...
Ammonia Volatilization and Selected Soil Characteristics Following Application of Anaerobically Digested Pig Slurry
January 1, 2000
Ammonia volatilization occurs shortly following land application of pig slurry. Several slurry and soil characteristics modulate the intensity of this process, and their net effect on volatilization...
Removal of dimethyl disulfide and p-cresol from swine facility wastewater using constructed subsurface-flow wetlands
January 1, 2000
Anecdotal evidence suggests that constructed wetlands can remove odors from veal, dairy, and swine wastes (Murphy and George, 1997; McCaskey, 1995). However, the use of constructed wetlands as an...
Corn response to composting and time of application of solid swine manure
January 1, 2000
Swine production in hoop structures is a relatively new husbandry system in which a mixture of manure and bedding accumulates. This manure/bedding pack can be applied to crop fields directly from a...
