The relationship between NH3 emissions from a poultry farm and soil NO and N2O fluxes from a downwind forest
Intensive livestock farms emit large concentrations of NH3, most of which is deposited very close to the source. The presence of trees enhances the deposition. Rates to downwind forests can exceed 40 kg N ha−1 y−1. The steep gradient in large NH3 concentrations of 34.3±20.4, 47.6±24.9, 21.7±16.8 μg NH3 m3 at the edge of a forest 15, 30 and 45 m downwind of the farm to near background concentrat...
متن کاملSoil N2O and NO emissions from an arid, urban ecosystem
[1] We measured soil nitrogen (N) cycling and fluxes of N2O and NO in three land-use types across the metropolitan area of Phoenix, Arizona. Urbanization increased N2O emissions compared to native landscapes, primarily due to the expansion of fertilized and irrigated lawns. Fluxes of N2O from lawns ranged from 18 to 80 mg N m!2 h!1 and were significantly larger than managed xeric landscapes (2....
متن کاملGaseous emissions (NH3, N2O, CH4, CO2) during pig slurry biological aerobic treatment and treatment by-product storages
Field measurements of ammonia (NH3), nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) were made from raw pig slurry storage, from different biological aerobic treatments and from stores holding the treated products. Biological treatments consisted of intermittent aeration by (i) submerged ejector aerator, (ii) surface aerator and (iii) fine-bubble diffuser. Emissions were measured fr...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
