Ammonia volatilization from liquid swine manure applied to cropland
Field experiments were conducted to determine the effects of rates and methods of liquid swine manure application on volatile NH3-N losses from cropland. A greenhouse study was conducted to determine...
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...

Efficacy of certain chemical and biological compounds for control of odor from anaerobic liquid swine manure
The effectiveness of various chemical and biological compounds in controlling the odors of anaerobically stored liquid manure was measured. The criteria for acceptable odor control were consistently...

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....

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...

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...
