-In 2020, NH<sub>3</sub>  emissions from category 3.I (agriculture other) derived up to 0.6 % from total agricultural emissions, which is equal to ~ 3.1 kt NH<sub>3</sub> . NO<sub>x</sub>  emissions from category 3.I contribute 0.16 % (~ 0.17 kt) to the total agricultural emissions.

-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 Rösemann et al. 2021, Chapter 10.2.1.)+The calculation of emissions from storage of digestate from energy crops considers two different types of storage, i.e. gastight storage and open tank.

Table REC-1 shows the effects of recalculations on NH<sub>3</sub> and NO<sub>x</sub> emissions from storage of anaerobically digested energy crops. Differences to last year’s submission occur only in 2018 and are due to the update of activity data (see main page of the agricultural sector, [[sector:agriculture:start|Chapter 5 - NFR 3 - Agriculture (OVERVIEW)]], **recalculation reason No 15**).
