The use of mineral fertiliser includes fertiliser used in parks, golf courses and private gardens. Approximately
1-2% of the mineral fertiliser can be related to this use outside the agricultural area.
As a result of increasing demands to an improvement in use of nitrogen in livestock manure, the
consumption of nitrogen in synthetic fertiliser has been halved from 1990 to 2003 (Table 6.16).

Manure applied to soil
The amount of nitrogen applied on soil is estimated as the N-excretion in stables minus the emission
of ammonia in stables, storage and in relation to application of manure. These values are
based on national estimations and are calculated in the ammonia emission inventory (Table 6.17).
The total N-excretion in stables from 1990 to 2003 has decreased by 7%. Despite this reduction in
N-excretion, the amount of nitrogen applied on soil is nearly unaltered, which is due to a reduction
in the ammonia emission.

The FracGASM is estimated as the total N-excretion (N ab animal) minus the ammonia emission in
stables, storage and application. The FracGASM has decreased from 0.26 in 1990 to 0.22 in 2003
(Table 6.18). This is a result of an active strategy to improve the utilization of the nitrogen in manure.
