Nutrient removal by grass components of vegetated buffer systems receiving swine lagoon effluent
January 1, 1993
Information is needed on nutrient removal mechanisms in vegetated buffer systems to assist in the design of these tong-term nutrient removal systems. We determined nutrient removal by grass portions...
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...
Surface application of liquid swine manure: Chemical variability
January 1, 1992By Michael E. Essington
The determination of manure loading rates for crop production is complicated by the temporal variability in manure nutrient concentrations and the difficulty in obtaining representative samples on...
Odor control in liquid hog manure by added amendments and aeration
January 1, 1992
A reduction in the emission of malodorous gases from liquid hog manure (LHM) would represent an advantage for LHM use in agricultural systems. Procedures for the reduction of disagreeable odors...
Field odor measurement and applications of Gaussian plume model
January 1, 1992
Field measurements of odour intensity around a slurry tank and 200-sow swine unit were conducted. Odour intensity from 0 to 3 were defined as none, detectable, strong, and very strong, respectively....
