Accumulation of Nutrients in Soil Beneath Hog Manure Lagoons
January 1, 1974By M. H. Miller
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
January 1, 1973By Larry D. King
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
January 1, 1973By P. W. Westerman
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
January 1, 1972By J.C. Burns
Swine (Sus scrofa domesticus ) production in confinement requires economical and environmentally safe waste management systems. Anaerobic lagoons require periodic removal of effluent for land...
Swine lagoon effluent applied to ‘Coastal’ Bermudagrass: II. Effects on soil
January 1, 1972
Effluent from animal waste lagoons can degrade water quality if allowed to discharge into surface waters. To determine the feasibility of using swine lagoon effluent as a source of water and...

Aeration with ORP [oxidation-reduction potentials] control to suppress odors emitted from liquid swine manure systems
January 1, 1971
An oxidation ditch, a method of extended aeration, was adapted to hog confinement systems to stabilize the manure in the pits beneath the animals (Day et al. 1969). The oxidation ditch adds enough...
