Greenhouse gas emission reduction and environmental quality improvement from implementation of aerobic waste treatment systems in swine farms
Trading of greenhouse gas (GHG) emission reductions is an attractive approach to help producers implement cleaner treatment technologies to replace current anaerobic lagoons. Our objectives were to...

Nitrous oxide emissions and soil mineral nitrogen status following application of hog slurry and inorganic fertilisers to acidic soils under forage grass
Field application of livestock slurry often results in higher nitrous oxide (N2O) emissions than inorganic fertiliser, because slurry contains large amounts of available N and C, and when applied it...

Process model for ammonia volatilization from anaerobic swine lagoons incorporating varying wind speeds and gas bubbling
Ammonia volatilization from treatment lagoons varies widely with the total ammonia concentration, pH, temperature, suspended solids, atmospheric ammonia concentration above the water surface, and...

Modeling studies of ammonia dispersion and dry deposition at some hog farms in North Carolina
A modeling study was conducted on dispersion and dry deposition of ammonia taking one hog farm as a unit. The ammonia emissions used in this study were measured under our OPEN (Odor, Pathogens, and...

Modeling hydrogen sulfide emissions across the gas-liquid interface of an anaerobic swine waste treatment storage system
Hydrogen sulfide (H2S) is a colorless gas emitted during decomposition of hog manure that produces an offensive "rotten egg" smell and is considered a toxic manure gas. In the southeastern...

Field sampling method for quantifying odorants in humid environments
Most air quality studies in agricultural environments use thermal desorption analysis for quantifying semivolatile organic compounds (SVOCs) associated with odor. The objective of this study was to...

Odor-reduction performance of constructed wetland treating diluted swine manure
The odor-reduction capability of livestock wastewater treatment wetlands has been primarily anecdotal and presented as a benefit beyond the already widely recognized attributes. The objective of this...

Influence of corn co-products on air emissions and nutrient excretions from grow-finish swine
Four diets were fed to growing swine in order to compare corn (C) to corn co-products and the impact on swine performance and air emissions. The corn co-product diets contained increasing levels of...

Utilization of crystalline amino acids by the gut in growing pigs
Excessive production of nitrogen from livestock production systems has place a strain on the environment. Methods to reduce nitrogen losses from farm animals will become necessary to ensure a...

Evaluation of Boric Acid and Sodium Tetraborate to Reduce Ammonia and Hydrogen Sulfide Emissions from Swine Facilities
Boric acid (BA) and sodium tetraborate (STB) were evaluated for their ability to inhibit ammonia and hydrogen sulfide emissions from swine wastewater and manure slurry in in vitro incubations....
