 +As no specific emission factor is known for the storage of digestion residues in open tanks, the NH<sub>3</sub> emission factor for storage of cattle slurry with crust in open tanks was adopted (0.045 kg NH<sub>3</sub> -N per kg TAN). This choice of emission factor is based on the fact that energy crops are, in general, co-fermented with animal manures (i. e. mostly slurry) and that a natural crust forms on the liquid digestates due to the relatively high dry matter content of the energy crops. 
  
-As no specific emission factor is known for the storage of digestion residues in open tanks, the NH<sub>3</sub>  emission factor for storage of cattle slurry with crust in open tanks was adopted (0.045 kg NH<sub>3</sub> -N per kg TAN). This choice of emission factor is based on the fact that energy crops are, in general, co-fermented with animal manures (i. e. mostly slurry) and that a natural crust forms on the liquid digestates due to the relatively high dry matter content of the energy crops. The TAN content after the digestion process is 0.56 kg TAN per kg N. The NO emission factor for storage of digestion residues in open tanks was set to 0.0005 kg NO-N per kg N. Table 3 shows the resulting implied emission factors for NH<sub>3</sub> -N and NO-N. NO<sub>x</sub>  emissions are related to NO-N emissions by the ratio of 46/14. This relationship also holds for NO-N and NO<sub>x</sub>  emission factors.+The TAN content after the digestion process is 0.56 kg TAN per kg N.
