Nutrient composition of Kansas swine lagoons and hoop barn manure.
A total of 312 samples in two experiments were analyzed to determine mean nutrient concentrations of swine lagoons and hoop barns in Kansas. First, in a retrospective study (Exp. 1), we obtained 41 sample analyses from the Kansas Department of Agriculture of sow, nursery, wean-to-finish, finish, and farrow-to-finish operations in 1999. The average total N concentration was 899 ppm (SD = 584 ppm...
متن کاملOdor and gas release from anaerobic treatment lagoons for swine manure.
Odor and gas release from anaerobic lagoons for treating swine waste affect air quality in neighboring communities but rates of release are not well documented. A buoyant convective flux chamber (BCFC) was used to determine the effect of lagoon loading rate on measured odor and gas releases from two primary lagoons at a simulated wind speed of 1.0 m s(-1). Concentrations of ammonia (NH3), hydro...
متن کاملDegradation and metabolite production of tylosin in anaerobic and aerobic swine-manure lagoons.
Watershed contamination from antibiotics is becoming a critical issue because of increased numbers of confined animal-feeding operations and the use of antibiotics in animal production. To understand the fate of tylosin in manure before it is land-applied, degradation in manure lagoon slurries at 22 degrees C was studied. Tylosin disappearance followed a biphasic pattern, where rapid initial lo...
متن کاملTECHNICAL REPORTS Atmospheric Pollutants and Trace Gases Odor and Gas Release from Anaerobic Treatment Lagoons for Swine Manure
releases are also needed to evaluate odor effects through science-based setback models (Lim et al., 2000). Odor Odor and gas release from anaerobic lagoons for treating swine is evaluated by determining odor concentration (OC), waste affect air quality in neighboring communities but rates of release are not well documented. A buoyant convective flux chamber (BCFC) intensity, and hedonic tone (H...
متن کاملReduction of Ammonia Emissions from Treated Anaerobic Swine Lagoons
There is a need for treatment technologies that can effectively address environmental concerns associated with anaerobic lagoons typically used to manage manure. These technologies must be able to capture nutrients, kill pathogens, and reduce emissions of ammonia (NH ) and nuisance odors. To meet these needs, a wastewater treatment plant was demonstrated at full-scale in one of two 4,360-pig pr...
