Developing revised emission factors for nitrous oxide emissions from agricultural pasture treated with nitrification inhibitors
Purpose
This report has two main purposes. Firstly, we review national and international literature on the effectiveness of nitrification inhibitors in reducing direct and indirect N2O emissions from grazing animal urine and dung excreta, nitrogen fertiliser and soils. Afterwards, we develop and use three revised methods to describe how anthropogenic emissions of N2O are reduced below that which would have occurred in the absence of the use of the nitrification inhibitors. The revisions included other aspects that are described in the next section.
