Nitrous Oxide Report for the UK 2016
To better reflect management systems within the UK, there is a move from what is essentially a Tier 1 structure (with some country specific activity data) to a Tier 2 structure using country specific emission factors (EFs)and improved activity data, and eventually towards a Tier 3 approach. This project builds upon the desk based review of country specific EFs in project AC0112 by the generation of measured EFs for direct (and some indirect) emissions of N2O from N fertilisers, manures and grazing returns of both dung and urine from a range of soils, farming systems and climatic zones of the UK. At experimental field sites, N2O EFs will be measured from the following key N sources: N fertilisers, manures, and dung and urine deposition by grazing stock.
