The implied emission factors relating to crops are expressed as total emission
divided by total area under cultivation, and are decreasing due to the
growth in set-a-side area. The implied emission factors for sewage sludge
and NH3 used for straw treatment remain unaltered.

From 1985 to 2010 the NH3 emission from agriculture other decreased from
12.56 Gg NH3 to 5.71 Gg NH3, which corresponds to a 55 % reduction (table
6.12). The decrease is mainly due to a decrease of NH3 used for treatment of
straw. NH3 treatment was prohibited by law in 2006 but in 2010 an exemption
were given due to wet weather.

This chapter only describes the PM emission related to the animal production.
The calculation of PM emission in connection to filed burning of agricultural
wastes is included in Chapter 6.6.

Investigations have shown that farmers, as well as livestock, are subject to
an increased risk of developing lung and respiratory related diseases due to
the particulate emissions (Hartung and Seedorf, 1999). This is since the particles
are able to carry bacteria, viruses and other organic compounds. Presently,
only the emission from 2000 to 2010 is given in NFR.
