Sensitivities of Four Air Dispersion Models to Climatic Parameters for Swine Odor Dispersion
January 1, 2007
Using air dispersion models to predict downwind livestock odor concentrations in order to establish science-based setback distances has the potential to become a common practice for regulatory...
Use of swine manure to improve solid-state fermentation in an integrated storage and conversion system for corn stover
January 1, 2007By Patrick T. Murphy
Swine manure contains a host of chemical and biological constituents which make it desirable for amending lignocellulosic biomass in storage for year round processing in a biorefinery. Application of...
Automated Image Analysis for Quantitative Fluorescence In Situ Hybridization with Environmental Samples
January 1, 2007
When fluorescence in situ hybridization (FISH) analyses are performed with complex environmental samples, difficulties related to the presence of microbial cell aggregates and nonuniform background...
Use of 13C abundance to study short-term pig slurry decomposition in the field
January 1, 2007
Applying pig slurry (PS) on agricultural soils is a common practice. However, its impact on soil organic C dynamics is not clear. This experiment investigated the use of natural 13C abundance to...
Crop residue effects on runoff nutrient concentrations following manure application
January 1, 2007By John E. Gilley
Manure is applied to cropland areas managed under diverse conditions, resulting in varying amounts of residue cover. The objective of this study was to measure the effects of crop residue on nutrient...
Compositional and functional features of humic acids from organic amendments and amended soils in Minnesota, USA
January 1, 2007
The use of organic amendments requires an adequate control of the chemical quality of their humic acid (HA)-like fractions and of the effects that these materials may have on the status, quality,...
Influence of slope position and hog manure injection on fall soil P and N distribution in an undulating landscape
January 1, 2007By Sumith K. R. Priyashantha
Investigation of how soil nutrients are distributed over the landscape in the fall is a prerequisite to identify critical source areas (CSA), which contribute soil nutrients to surface waters through...
Nitrification monitoring in a biofilter treating pig manure
January 1, 2007
BACKGROUND: Nitrogen removal by organic biofilters treating pig manure is incomplete and has to be optimized. This could be achieved by promoting the activity of denitrifiers, this being the limiting...
Dissolved organic carbon in runoff and tile-drain water under corn and forage fertilized with hog manure
January 1, 2007By Crops Research and Development Centre|I. Royer Soils
Dissolved organic carbon (DOC) export from soils can play a significant role in soil C cycling and in nutrient and pollutant transport. However, information about DOC losses from agricultural soils...
Impacts of waste from concentrated animal feeding operations on water quality
January 1, 2007By P.S. Thorne
Waste from agricultural livestock operations has been a long-standing concern with respect to contamination of water resources, particularly in terms of nutrient pollution. However, the recent growth...
