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
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
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
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
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
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
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
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
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
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...
Odor control in liquid hog manure by added amendments and aeration
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...
