Denitrification in a Coastal Plain Riparian Zone Contiguous to a Heavily Loaded Swine Wastewater Spray Field
January 1, 1994
Riparian zones are recognized worldwide as important landscape features that are able to buffer streams from pollutants, particularly nitrogen. The objectives of this experiment were to 1) assess the...
Effects of swine lagoon effluent and commercial fertilizer applications on phosphorus status of an acid and alkaline soil
January 1, 1994By Ardeshir Adeli
Two separate field experiments were conducted in Brooksville, Mississippi to evaluate the effects of swine lagoon effluent relative to inorganic fertilizer at equivalent rates on phosphorus (P)...
Headspace analysis of malodorous compounds from swine wastewater under aerobic treatment
January 1, 1994By A. Chen
Static headspace sampling and gas chromatograph (GC) analyses were used to monitor the concentration of malodorous compounds (volatile fatty acids (VFA), phenol, p-cresol, indole, and skatole)...
Potential reduction of struvite formation from anaerobic swine lagoon effluent by treatment in constructed wetlands
January 1, 1994By Dennis M. Sievers
Effluents from both cells of a two-cell anaerobic lagoon system treating flushed swine waste from the University of Missouri Swine Farm were treated in parallel constructed wetlands - submerged flow...
Treatment of Swine Wastewater Using a Saturated-Soil-Culture Soybean and Flooded Rice System
January 1, 1993By P. G. Hunt
Constructed wetlands have potential for treatment of livestock wastewater, but they generally contain wetland plants rather than agronomic crops. We evaluated two agronomic crops,...
Designing Riparian Buffer Systems for Utilization and Treatment of Effluent
January 1, 1993By R. K. Hubbard
Management techniques for using riparian buffer systems to utilize and treat agricultural effluents are being developed in at the Coastal Plain Experiment Station, Tifton, GA. Riparian systems...
Challenges of managing liquid swine manure
January 1, 1993By Douglas L. Karlen
Liquid swine manure can be a resource for providing essential plant nutrients and building soil resources, but its management for maximum productivity with minimum environmental impact is often very...
Characterization of particles, ammonia and endotoxin in swine confinement operations
January 1, 1993
Total and respirable dust particles, ammonia and endotoxin were measured in the nursery and grower areas of 4 swine confinement houses during January-March and April-June. Increased ventilation in...
Denitrification from a swine lagoon overland flow treatment system at a pasture-riparian zone interface
January 1, 1993By Richard Lowrance
In manure disposal systems, denitrification is a major pathway for N loss and to reduce N transport to surface and ground water. We measured denitrification and the changes in soil N pools in a...
Effects of liquid swine manure applications on NO3-N leaching losses to subsurface drainage water from loamy soils in Iowa
January 1, 1993By A. Bakhsh
Long-term applications of organic or inorganic sources of N to croplands can increase the leaching potential of nitrate-nitrogen (NO3-N) for soils underlain by subsurface drainage "tile"...
