5.9.6 Source-specific recalculations
The 2015 submission is the first year that CO 2 emissions from urea have been reported
under the requirement from the IPCC (2006) guidelines, and no recalculations have
been performed.
5.9.7 Source-specific planned improvements
New Zealand will continue to update activity on urea as the data become available from
the Fertiliser Association of New Zealand and the International Fertilizer Industry
Association. A review of synthetic fertiliser data availability and uncertainty in
New Zealand is planned in future.
5.10 Other carbon-containing fertilisers (CRF 3.I)
5.10.1 Description
The IPCC (2006) guidelines do not provide guidance for reporting on other carboncontaining
fertilisers. Other carbon-containing synthetic fertilisers besides limestone,
dolomite and urea (sections 5.8 and 5.9) are not applied to agricultural land in
New Zealand (van der Weerden and de Klein, pers. comm., 2015).
Manure application to agricultural land will slowly mineralise, producing a small amount
of CO 2 as a by-product, but these losses are unlikely to be significant for New Zealand
(van der Weerden and de Klein, pers. comm., 2015). This category is therefore reported
as not estimated (NE).
