Guidebook Update - Agriculture chapters – Crop ammonia emissions J Webb on behalf of Ricardo-AEA and Aether and with input from Aarhus University and the EAGER group

Task 3.iii: Ammonia emissions from standing crops Yet again we are attempting to determine is a discrete emission estimate can be made of NH3 emissions from standing crops These emissions have been discussed frequently at TFEIP meetings and was recently identified as an area where greater collaboration with the modelling community was required the objective of Task 3iii is to review existing information concerning NH3 from standing crops, and develop appropriate methodologies for the Guidebook the work will be carried out by means of a literature review a key reference to use as the starting point for the review will be that of Asman (2009) any suggestions of modellers we can consult?
