Modelling groundwater contamination from land-applied swine waste
A one-dimensional model based on the flow and convection/dispersion equations was developed to simulate water table fluctuations and nitrate distribution in a shallow unconfined aquifer during...
Odor control of liquid dairy and swine manure using chemical and biological treatments
Swine manure and lagoon effluent applied to a temperate forage mixture. II. Rainfall runoff and soil chemical properties
Rates of swine (Sus scrofa domesticus) waste used for crop production must be sufficient to supply adequate nutrients but must not pose a surface or groundwater pollution hazard. To determine...
Swine waste nutrient recovery system based on the use of thermal discharges
None available.
Swine Manure and Lagoon Effluent Applied to a Temperate Forage Mixture: I. Persistence, Yield, Quality, and Elemental Removal
Swine (Sus scrofa domesticus) waste can be a nutrient source for crops when applied as a manure slurry or lagoon effluent. Limited land area for disposal may result in high application rates. Yet...
Pollutant movement to shallow groundwater tables from anaerobic swine waste lagoons
The effect of three anaerobic swine waste lagoons on ground water quality was investigated in the Atlantic Coastal Plain region. The lagoons studied were located on high-water table soils with...
Accumulation of Nutrients in Soil Beneath Hog Manure Lagoons
The soil beneath four hog manure lagoons was samples and analyzed for NO3-N, NH4-N and soluble P. Nitrate levels were essentially zero in all samples taken shortly after the lagoons were emptied....
Long-term swine lagoon effluent applications on ‘Coastal’ bermudagrass. II. Effect on nutrient accumulation in soil
Application of effluent from animal manure lagoons to cropland is an effective method of utilizing the nutrients in the effluent and minimizing groundwater and surface-water pollution. The objective...
Swine lagoon effluent applied to ‘Coastal’ Bermudagrass: III. Irrigation and Rainfall runoff
In moisture excess regions, irrigation of lagoon effluent to land is generally required to prevent water pollution from lagoon overflow. However, the land area receiving lagoon effluent then becomes...
Swine lagoon effluent applied to "coastal" bermudagrass. I. Forage yield, quality, and element removal
Swine (Sus scrofa domesticus ) production in confinement requires economical and environmentally safe waste management systems. Anaerobic lagoons require periodic removal of effluent for land...
