Dietary manipulation of sulfur for reduced H2S emission from swine waste
July 1, 1998
This experiment was conducted to evaluate H2S production rates from nursery pig swine manure stored in simulated waste storage pits as influenced by sulfur content of the diets fed. Waste from six...
Nutritive value of timothy fertilized with chloride or chloride-containing liquid swine manure
January 1, 1998By Agri-Food Canada|S. Pelletier Agriculture
Chloride fertilization of timothy (Phleum pratense L.) decreases forage dietary cation-anion difference to an acceptable value [(
Dispersion of Volatile Organic Compounds around Swine Production Facilities in the United States
January 1, 1998
Dispersion of odors, gases, and particulates from swine production and manure storage facilities creates a problem with neighbors. It is assumed that all materials emitted by production units rapidly...
Covered anaerobic lagoon system for swine waste treatment and energy recovery
January 1, 1998By Jiayang Cheng
A covered anaerobic lagoon system for swine manure management has been evaluated for its performance. The system consists of a covered anaerobic lagoon for primary treatment and a conventional lagoon...
Application of Mixed and Aerated Pond for Nitrification and Denitrification of Flushed Swine Manure
January 1, 1998By Philip Westerman
A nitrification/denitrification system for flushed swine manure was evaluated for treating manure from 3000 finishing pigs. The system consisted of a pond with a mixing zone for denitrification...
Experiences with a biofilter on a slatted floor hog barn
January 1, 1998
A biofilter was installed for the removal of odorous gases from the pit ventilation air of a slatted floor pig finishing barn and was studied over a 2 year period. The biofilter was effective in...
Swine effluent irrigation rate and timing effects on bermudagrass growth, nitrogen and phosphorus utilization, and residual soil nitrogen
January 1, 1998By A. Adeli
Maximizing utilization of effluent nutrients by forage grasses requires a better understanding of irrigation rate and timing effects. This study was conducted in 1998 and 1999 on a Vaiden silty clay...
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...
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...
Seepage losses and nitrogen export from swine-waste lagoons: a water balance study
January 1, 1998
Seepage losses from animal-waste lagoons could affect ground water quality. Water balance methods were used to study seepage and nitrogen export from three swine-waste lagoons in southwestern...
Distribution of ammonium-N in the water-soil interface of a surface-flow constructed wetland for swine wastewater treatment
January 1, 1998
Most livestock wastewaters treated in constructed wetlands are typically rich in ammonium N. The objective of this study was to evaluate the soil-water ammonium distribution and the diffusive flux...
Denitrification following land application of swine waste to bermudagrass pasture
January 1, 1998By D. G. Sullivan
Nitrogen (N) losses following land-applied animal wastes present an environmental and economical dilemma for producers. Gaseous N losses from pastureland contribute to global warming, ozone...
