Nutrient Transport as Affected by Rate of Overland Flow
January 1, 2002By John E. Gilley
Little information is currently available concerning the effects of varying flow rate on nutrient transport by overland flow. The objective of this study was to measure the effects of overland flow...
Effects of temperature, soil water status, and soil type on swine slurry nitrogen transformations
January 1, 2002
Manure N dynamics are affected by manure characteristics, soil factors, and environmental conditions. An incubation experiment was conducted to assess the relationship of these factors. The effects...
Effect of liquid swine manure rate, incorporation, and timing of rainfall on phosphorus loss with surface runoff
January 1, 2002By B.L. Allen and A.P. Mallarino
Excessive manure phosphorous (P) application increases risk of P loss from fields. This study assessed total runoff P (TPR), bioavailable P (BAP), and dissolved reactive P (DRP) concentrations and...
Stratification of solids, nitrogen and phosphorus in swine manure in deep pits under slatted floors
January 1, 2002
Manure slurries stored in pits under slatted floors of both finishing and nursery barns were sampled at four different depths to study stratifications of total solids (TS) and nutrients (nitrogen and...
Characterizing ammonia emissions from swine farms in eastern north carolina: Part 1-conventional lagoon and spray technology for waste treatment
January 1, 2002By Aneja Viney P.
Ammonia (NH3) fluxes from waste treatment lagoons and barns at two conventional swine farms in eastern North Carolina were measured. The waste treatment lagoon data were analyzed to elucidate the...
Retention of nitrogen and phosphorous from liquid swine and poultry manures using highly characterized peats
January 1, 2002
This paper reports on research designed to test the hypothesis that differences in peat composition will cause differences in amounts of N and P retained during contact with liquid swine manure (LSM)...
Antibiotic-resistant enterococci and fecal indicators in surface water and groundwater impacted by a concentrated swine feeding operation
January 1, 2002By A.R. Sapkota
BACKGROUND: The nontherapeutic use of antibiotics in swine feed can select for antibiotic resistance in swine enteric bacteria. Leaking swine waste storage pits and the land-application of swine...
Protocol Development for Measurement of Trace Gases Associated with Manure Storage and Odor
December 31, 2001By Wendy Powers
Quantification of odorous compounds associated with livestock odors has been difficult
in the past due to sensitivity limitations of available instrumentation. Advances in
instrumentation have helped...

Ambient odour testing of concentrated animal feeding operations using field and laboratory olfactometers
November 1, 2001By B. D. Newby
The Missouri Air Conservation Commission regulations include regulations that limit the amount of acceptable odor from confined animal feeding operations (CAFOs). The regulations concerning odor...
