Evaluation of targeted or additional straw use as a means of reducing NH3 emissions from buildings housing cattle & pigs - AM0103

Description
The overall objective of the study is to evaluate the effects of additional or targeted straw usage on reducing ammonia emissions from housed livestock. This information, in addition to that obtained from the MAFF project WA0716, To determine the effect of storage conditions on ammonia emissions from solid manures heaps, will allow a more complete evaluation of ammonia emissions from solid manure based systems to be made.
To achieve this objective, studies will be conducted at ADAS Terrington and IGER North Wyke to investigate effects of contrasting levels of straw use on ammonia emissions from pigs and cattle housed in experimental facilities. Measurements will also be made from commercial animal houses, to assess the impact of changing straw use.
This work supports MAFF’s policy objectives of quantifying and limiting ammonia losses from agricultural systems, and improving the utilisation of nutrients from farm manures. The work will assist in implementing the EU Integrated Pollution Prevention and Control Directive (IPPC) by developing practical guidelines for farmers on the best methods of housing pigs to limit ammonia emissions from straw based systems. The data will also support UK discussions as part of the UNECE Convention on Long-Range Transboundary Air Pollutants and the EU Acidification Strategy.
Objective
The overall objective of the study is to quantify the effects of increasing straw use and targeted straw use on ammonia emissions from animal buildings.

Specific objectives are :
1) To quantify the effect of different amounts of straw bedding on ammonia emissions from buildings housing cattle and pigs.

2) To quantify the effect of targeted straw use on ammonia emissions from buildings housing cattle and pigs.

3) To make measurements from commercial buildings to assess the impact of changing straw use.
