-In 2024, NH<sub>3</sub> emissions from category 3.I (agriculture other) amounted to 0.26 % of total agricultural emissions, which is equal to ~ 1.3 kt NH<sub>3</sub>. NO<sub>x</sub> emissions from category 3.I contribute 0.07 % (~ 0.07 kt) to the total agricultural emissions. All these emissions originate from the storage of digestate from energy crops (for details on anaerobic digestion of energy crops see Vos et al.

-The calculation of emissions from storage of digestate from energy crops considers two different types of storage, i.e. gastight storage and open tank. The frequencies of these storage types are also provided by KTBL (see Table 2). There are no emissions of NH<sub>3</sub>  and NO from gastight storage of digestate. Hence the total emissions from the storage of digestate are calculated by multiplying the amount of N in the digestate leaving the fermenter with the relative frequency of open tanks and the emission factor for open tank. The amount of N in the digestate leaving the fermenter is identical to the N amount in energy crops fed into anaerobic digestion (see Table 1) because N losses from pre-storage are negligible and there are no N losses from fermenter (see Vos et al. 2026, Chapter 5.1).+The calculation of emissions from storage of digestate from energy crops considers two different types of storage, i.e. gastight storage and open tank.
