Nitrogen assimilation by riparian buffer systems receiving swine lagoon wastewater
January 1, 1993By Robert K. Hubbard
A three-year study was conducted to determine the feasibility of using riparian buffer systems to assimilate nitrogen (N) from swine lagoon effluent. Replicated 30X4 m plots were established at the...
Simulating the effect of swine manure application on NO3-N transport to subsurface drainage water
January 1, 1993By Allah Bakhsh
The root zone water quality model (RZWQM V.3.25) was calibrated and evaluated using four years (1993-96) of field data to simulate the effect of swine manure application on NO3-N losses with...
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...
Evaluation of overland flow treatment for swine lagoon effluent
January 1, 1992By Gary L. Hawkins
Overland flow, on slopes of 5 and 11%, was used as a means of treating wastewater effluent from the second cell of a swine waste anaerobic lagoon system. Wastewater samples from both surface runoff...
Surface water quality impacts of tillage practices under liquid swine manure application
January 1, 1992By R. P. Rudra
Field studies were conducted to investigate the effects of tillage practices on the saturated hydraulic conductivity, and quantity and quality of surface runoff water resulting from the application...
Effectiveness of Vegetative Filter Strips in Retaining Surface-Applied Swine Manure Constituents
January 1, 1992By Indrajeet Chaubey
Simulated rainfall was used to evaluate the effectiveness of vegetative filter strips (VFS) of varying lengths (0, 3, 6, 9, 15, and 21 m) in reducing sediment and nutrient losses from plots treated...
