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...
Application of nitrogen from swine lagoon effluent to bermudagrass pastures: seasonal changes in forage nitrogenous constituents and effects of energy and escape protein supplementation on beef cattle performance
January 1, 1993By R. W. Harvey
A 2-yr study was conducted to evaluate 1) the effects of nitrogen level from swine lagoon effluent on forage composition and animal performance and 2) the effects of supplemental escape protein (EP)...
A swine waste package biotreatment plant for the tropics
January 1, 1993By P. Y. Yang
Management of small pig waste/wastewater in the tropics is considered as a rather difficult problem, especially in the land limited and populated areas. In order to eliminate the problem or...
Composting of separated solid swine manure
January 1, 1993By P. H. Liao
A study was conducted to investigate the efficiency of the composting process when the initial moisture content is higher than the generally recommended limit of 65%. Solids separated from swine...
A land-limited and energy-saving treatment system for dilute swine wastewater
January 1, 1993
A combined bio-fixed film and aquatic plant (CBFFAP) system was investigated for treatment of diluted swine waste and anaerobically digested effluent under tropical-climate and land-limited...
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...
