NH3 emission from agricultural soils contributes with 8 % of the total emission
from the agricultural sector and includes emission from use of synthetic
fertiliser and emission from nitrogen deposited by grazing animals. In 2010
approximately 65 % of the emission from agricultural soils originates from
synthetic fertiliser.

More detailed description covering the calculation of the emission sources
and information about activity data and emission factors used is given in
annex 2C2.

At present, farmed area covers about 60 % of the total land area in Denmark.
In recent decades, farmed area has decreased, being replaced by forest, seminatural,
road and built-up areas and this development is expected to continue.
Table 6.7 shows the activity data used in calculation of the NH3 emission
from agricultural soils. The amount of nitrogen used in synthetic fertiliser
is based on information from the Danish Plant Directorate. The use of
fertiliser has decreased considerably – consumption in 2010 is almost half
that in 1985. The increase of fertiliser from 2007 to 2008 can mainly be explained
by expectations of rising prices and cultivation of fallow fields,
which also can explain the decrease in 2009.
