This studentship explores the relationship between atmospheric ammonia concentrations at the landscape scale and agricultural management practices at the field and farm scale for predominantly grassland-based agricultural systems. Ammonia is a significant contributor to nitrogen deposition, damaging sensitive ecosystems, and largely arises from agricultural sources.<\/p>\n
There is a drive for sustainable intensification within the agricultural sector to improve both productivity and environmental management of land. More knowledge is required, particularly in grassland-based production systems, of the effects that management changes such as sward composition and stocking density can have on ammonia emissions to the wider environment.<\/p>\n
The aims of this project therefore are, within the context of grassland-based agricultural systems:<\/p>\n
\u2022 to derive ammonia emission factors\/algorithms for the different components of the production systems (grazing, housing, manure storage and spreading, mineral fertilizer application) and assess the influence of the different managements;<\/p>\n
\u2022 to model ammonia emissions at the whole farm\/system scale for different management systems based on the component measurements;<\/p>\n
\u2022 to model local ammonia concentrations based on farm-scale emissions and dispersion modelling and comparison with a local measurement network<\/p>\n
The research will be based largely on the North Wyke Farm Platform (www.rothamsted.ac.uk\/farmplatform) and also at Bangor University Henfaes research facility (http:\/\/www.bangor.ac.uk\/senrgy\/research\/facilities\/henfaes.php.en), with expertise in measuring ammonia concentrations and atmospheric dispersion modelling provided by CEH, Edinburgh.<\/p>\n
In addition to the generic training in good scientific practice, scientific writing and presentation skills, etc., the student will receive specific training in:<\/p>\n
\u2022 measurements of atmospheric ammonia concentrations<\/p>\n
\u2022 laboratory and field-scale measurements of emissions from a range of agricultural sources<\/p>\n
\u2022 laboratory methods for the characterization of livestock manures<\/p>\n
\u2022 environmental modelling (farm-scale ammonia emission modelling; atmospheric dispersion modelling)<\/p>\n
The studentship will involve travel between the North Wyke, Bangor and CEH Edinburgh sites and it is expected that the student will attend relevant international conferences to present their research.<\/p>\n
Eligibility: Applicants should hold a minimum of a UK Honours Degree at 2:1 level or equivalent in Environmental Science or similar subject. A strong mathematical background and some skills\/experience of environmental modelling would be an advantage. Applicants should have a full, clean driving license.
