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...
Equilibrium sampling used to monitor malodors in a swine waste lagoon
January 1, 2006By J.H. Loughrin and N. Lovanh
The concentrations of malodorous compounds in a 0.4-ha anaerobic lagoon that received waste from approximately 2000 sows were monitored during the late summer to late fall of 2006 to gain insight...
Effect of microbial additives combined with aeration on reduction of nutrients in swine manure
January 1, 2006By JUN ZHU
The research presented in this article evaluated a technique using manure additives (Sporzyme and activated sludge) coupled with aeration treatment in reducing nutrients from liquid swine manure....
Factors Influencing Illinois Farmland Values
January 1, 2006By Haixiao Huang
A hedonic model of Illinois farmland values is estimated using county-level cross-section time-series
data. Explanatory variables include land productivity, parcel size, improvements, distances to...
Isolation of Salmonella bacteriophages from swine effluent lagoons
January 1, 2006By M.R. McLaughlin United States Department of Agriculture
Bacteriophages (phages) associated with Salmonella were collected from nine swine manure lagoons in Mississippi. Phages were isolated by an enrichment protocol or directly from effluent. For...

Disposal of Swine Lagoon Sludge with Nutrient Recovery
December 21, 2005By M. Todd See
Gasification offers many advantages for processing undesirable waste materials. Tests on gasifier emissions reveal very low levels of NOx, SOx and volatile organic carbons in the flue gas, well...
