Ammonia Emissions from Agricultural Operations: Livestock
The global abundance of N fertilizer has dramatically increased agricultural productivity. However, when N escapes to the atmosphere as ammonia (NH 3 ) gas, NH 3 loss can cause undesirable effects. In addition to a loss of a valuable resource, it can have negative impacts on air quality, ecosystem productivity, and human health. Animal production is the largest source of NH 3 emission in North ...
متن کاملPractices to Reduce Ammonia Emissions from Livestock Operations
filtration may be costly, biofiltration can effectively and inexpensively reduce exhaust odors. Biofiltration costs for a 700-head farrow-to-wean swine facility are estimated at $0.25 per piglet, amortized over a 3-year life of the biofilter. Reductions of ammonia emission at that operation are approximately 74 percent, whereas reductions in both hydrogen sulfide and odor emissions are about 90...
متن کاملAn assessment of ammonia emissions from dairy facilities in Pennsylvania.
A survey of 715 Holstein dairy farms in Pennsylvania was used to construct demographics for the average Holstein dairy farm. The average Holstein dairy farm was composed of 69 lactating cows; 11 nonlactating, pregnant cows; 44 heifers; and 18 calves. Milk production averaged 27.3 kg (60.0 lb). Crop area averaged 73.6 ha. Milk production, crop area and type, average county yields, and herd anima...
متن کاملReactive nitrogen emissions from crop and livestock farming in India
Recent studies suggest that human activities have accelerated the production and emissions of reactive nitrogen on a global scale. Increased nitrogen emissions may lead to environmental impacts including photochemical air pollution, reduced visibility, changes in biodiversity, and stratospheric ozone depletion. Emissions from agricultural activities, both crop and animal, are known to contain r...
متن کاملAirborne reduced nitrogen: ammonia emissions from agriculture and other sources.
Ammonia is a basic gas and one of the most abundant nitrogen-containing compounds in the atmosphere. When emitted, ammonia reacts with oxides of nitrogen and sulfur to form particles, typically in the fine particle size range. Roughly half of the PM(2.5) mass in eastern United States is ammonium sulfate, according to the US EPA. Results from recent studies of PM(2.5) show that these fine partic...
