6.4.2.1 Direct Emissions<br />

Syn<strong>the</strong>tic fertiliser<br />

The amount of nitrogen (N) applied on soil by use of syn<strong>the</strong>tic fertiliser is estimated from sale estimates<br />

by <strong>the</strong> Danish Plant Directorate. The amount of N is minus <strong>the</strong> ammonia emission based<br />

on national estimates from DIAS (Sommer and Christensen 1992, Sommer and Jensen 1994, Sommer<br />

and Ersbøll 1996). The Danish value for <strong>the</strong> FracGASF is estimated to 0.02 and is considerably<br />

lower than given in IPCC, i.e. 0.10. The ammonia emission depends on fertiliser type and <strong>the</strong> lower<br />

FracGASF is probably due to a small consumption of urea (
