The calculated emission is based on the air EMEP/EEA air pollutant emission
inventory guidebook (EMEP/EEA, 2009).
The emissions from agricultural activities include NFR Table 4B Manure
Management, Table 4D Agricultural Soils, Table 4F Field Burning of Agricultural
Wastes and Table 4G Agriculture Other. In general the field burning of
agricultural wastes has been prohibited since 1989. However, burning of
straw may only take place in connection with fields continuously cultivation
of seed grass or in cases where weather conditions result in surplus of straw
in form of wet or broken bales.
The emission is calculated as the sum of activities (ai) multiplied by the implied
emission factor (IEF) for each activity, L.
E = ∑a • IEF

The emissions from the agricultural sector are calculated in a comprehensive
agricultural model complex called IDA (Integrated Database model for Agricultural
emissions). The model complex is designed in a relational database
system (MS Access). Input data are stored in tables in one database
called IDA_Backend and the calculations are carried out as queries in another
linked database called IDA. The model, as shown in Figure 6.3, is implemented
in great detail and it is used to cover emissions of NH3, PM, NOx,
CO, NMVOC, SO2, heavy metals, dioxin, PAH and greenhouse gases (N2O
and CH4). Thus, there is direct coherence between the NH3 emission and the
emission of N2O.
