Use of polyacrylamide in simulated land application of lagoon effluent: Part II. Nutrient loss
January 1, 2006By Dennis C. Flanagan
Land application of agricultural wastewater can contribute to eutrophication of water bodies by increasing the quantities of dissolved and particulate nutrients that are transported in runoff during...
Treatment of swine manure effluent using freshwater algae: Production, nutrient recovery, and elemental composition of algal biomass at four effluent loading rates
January 1, 2006By Walter W. Mulbry United States Department of Agriculture
Cultivating algae on nitrogen (N) and phosphorus ( P) in animal manure effluents presents an alternative to the current practice of land application. The objective of this study was to determine how...
Multi-component analysis of tetracyclines, sulfonamides and tylosin in swine manure by liquid chromatography-tandem mass spectrometry
January 1, 2006By A. M. Jacobsen
A multi-component method focussing on thorough sample preparation has been developed for simultaneous analysis of swine manure for three classes of antibiotic-tetracyclines, sulfonamides, and...
Use of polyacrylamide in simulated land application of lagoon effluent: Part I. Runoff and sediment loss
January 1, 2006By Dennis C. Flanagan
Agriculture contributes considerably to water quality problems in the U.S. Tillage systems and land application of wastewaters from animal production facilities can increase both sediment and...
Developing an environmental manure test for the phosphorus index
January 1, 2006By Peter J. A. Kleinman
Widespread implementation of the phosphorus (P) index has focused attention on environmental manure tests that can be used to estimate the relative availability of P in manure to runoff water. This...
Methane and carbon dioxide emissions from simulated anaerobic swine manure treatment lagoons under summer conditions
January 1, 2006
Most estimates of carbonaceous gas emissions from manure treatment lagoons are based on biogas production from anaerobic digesters, gases collected over covered lagoons, or the CH4 production...
Sorption of inorganic and total phosphorus from dairy and swine slurries to soil
January 1, 2006
Understanding P sorption from animal manures is essential to formulate best management practices with regard to land application of manure from the standpoint of crop production and environmental...
Effect of swine and dairy manure amendments on microbial communities in three soils as influenced by environmental conditions
January 1, 2006By R. P. Larkin
Understanding the impacts of manure amendments on soil microorganisms can provide valuable insight into nutrient availability and potential crop and environmental effects. Soil microbial community...
Distribution of phosphorus in manure slurry and its infiltration after application to soils
January 1, 2006By Peter Vadas
Computer models help identify agricultural areas where P transport potential is high, but commonly used models do not simulate surface application of manures and P transport from manures to runoff....
A Laboratory Scale Sequencing Batch Reactor with the Addition of Acetate to remove Nutrient and Organic Matter in Pig Slurry
January 1, 2006By J. Zhu
The influence of carbon addition on performance of a laboratory-scale, anaerobic-anoxic-anaerobic-anoxic sequencing batch reactor [(An/Ax)2 SBR] in biologically removing nitrogen and organic matter...
