-Since 2016, fertilizer sales have fallen dramatically (by around a third). Emissions have fallen accordingly. This is even more pronounced for NH<sub>3</sub> than for NO<sub>x</sub>, as total NH<sub>3</sub> from the application of mineral fertilizers is, until the year 2019, very strongly correlated with the amount of urea applied (R<sup>2</sup> = 0.64), the sales of which have decreased more than for all other mineral fertilizers. Since 2020 the negative trend is reinforced as urea fertilizer have to be either used with urease inhibitors or have to be incorporated into the soil directly, which reduces emissions. +Since 2016, fertilizer sales have fallen dramatically (by around a third).

 Both NH<sub>3</sub> and NO<sub>x</sub> emissions from the application of animal manure are key sources. Total NO<sub>x</sub> is calculated proportionally to the total N applied with manure which decreased remarkably from 1990 to 1991 due to the decline in animal numbers following the German reunification (reduction of livestock numbers in Eastern Germany). In the 1990s and 2000s this was followed by a weakened decline in animal manure amounts. From 2010 to 2014 there was a slight increase and since then the amount of N in manure applied has been declining again, see Table 5. The NO<sub>x</sub> emissions follow these trends. For total NH<sub>3</sub> emissions there is a negative trend. This is due to the decreasing amounts of animal manure and the increasing use of application practices with lower NH<sub>3</sub> emission factors.  Both NH<sub>3</sub> and NO<sub>x</sub> emissions from the application of animal manure are key sources.

-For all years, the total emissions of NH<sub>3</sub> and NO<sub>x</sub> from application of manure are slightly higher than those of last year’s submission. +Until 2000, the total emissions of NH<sub>3</sub> from application of manure are higher than those of last year’s submission and thereafter they are lower. For NO<sub>x</sub> the changes are similar, however the change from higher to lower values takes place 20 years later
  
-These differences are predominantly caused by a higher estimate of manure N, which is applied, compared to the last submission. Many of the recalculations have an effect on this. The two most important ones are **No. 3** (lower NH<sub>3</sub> emission factors for cattle and pig housing result in more N available for spreading) and **No. 4** (correction of horse numbers by a factor of 2.75), both of which increase emissions see [[sector:agriculture:start|main page of the agricultural sector]], list of recalculation reasons.  +These differences are predominantly caused by different estimates of manure N, which is applied, compared to the last submission. Many of the recalculations have an effect on this, especially the **recalculations No. 2, No. 3, No. 4, No. 5, and No. 6**. The two most important ones are **No. 3** (the new methodology to calculate N and TAN excretions of dairy cows leads to higher N excretion at the beginning and lower N excretions at the end of the time series, the percentage shares of TAN are lower for all years. The latter is responsible for the earlier change in the trend of NH<sub>3</sub> emissions) and **No. 4** (higher milk yields generally increase excretions), see [[sector:agriculture:start|main page of the agricultural sector]], list of recalculation reasons.

-Activity data is the amount of N in residues from anaerobic digestion of energy crops and waste and of compost from biowaste and green waste when leaving storage, as well as the amount of N in imported animal manures. For energy crops this is the N contained in the energy crops when being fed into the digestion process minus the N losses by emissions of N species from the storage of the residues (see 3.I). N losses from pre-storage are negligible and there are no N losses from fermenter (see Rösemann et al. (2025), Chapter 5.1). For residues from digested waste, compost from biowaste and compost from green waste the amount of N was derived from the waste statistics of the Federal Statistical Office (see Rösemann et al.

For imported manure the amounts of N were derived from statistics published by CBS (Statistics Netherlands) and RVO (Rijksdienst voor Ondernemend Nederland) The imported manure is categorized into cattle slurry, pig slurry, poultry manure, horse manure and mixed solid manure.

-The NH<sub>3</sub> emissions are calculated the same way as the NH<sub>3</sub> emissions from application of animal manure (3.D.a.2.a). The frequencies of application techniques and incorporation times as well as the underlying data sources are provided e. g. in the NID 2025, Chapter 17.3.1. It is assumed that residues of digested waste are applied in the same way and have the same emission factors as residues from digested energy crops. For compost from biowaste and green waste it is assumed that they are applied in the same way and have the same emission factors as cattle solid manure. The amounts of TAN in the residues from digested energy crops applied are obtained from the calculations of emissions from the storage of the digested energy crops (3.I). The amounts of TAN in the residues from digested waste, compost from biowaste and compost from green waste are derived from industry data (provided by Bundesgütegemeinschaft Kompost, BGK). For the imported manures it is assumed that the different imported manure types (see above) were applied in the same way as the corresponding domestic animal manure types. Mixed manure was treated like solid manure from goats, sheep and horses. Corresponding TAN contents were derived from publications of the German federal states. As published TAN contents vary strongly, for each imported manure type the maximum of published TAN contents was assumed to prevent an underestimation of the NH<sub>3</sub> emissions.

-Recalculations after 2013 are mainly due to the update of activity data. Concerning NH<sub>3</sub> emissions, small differences occur in all years. This is because the underlying spatial distribution of imported manure is different, which results in different IEFs compared to last year’s submission. Another reason is the interpolation of RAUMIS distribution data before 1999 (see [[sector:agriculture:start|main page of the agricultural sector]], list of recalculation **reasons19, 20 and 21**, and Rösemann et al.

For NO<sub>x</sub> emissions from grazing in all years are higher than those of last year’s submission. **Recalculations No. 3** (new methodology to calculate N and TAN excretions of dairy cows) and **No4** (higher milk yields) lead in combination to higher N excretion of dairy cowsespecially at the beginning of the time seriesbut to lower TAN excretions for all years. Since NH<sub>3</sub> emissions are related to TAN excretion and NO<sub>x</sub> emissions are related to N excretion, this leads to lower NH3 and higher NO emissions. **Recalculation No. 6** (higher N (and TAN) excretion for heavy horses as of 2011) is the reason why, after 2012, NH<sub>3</sub> emissions are higher compared with last year’s submission.

 ==== Methodology ==== ==== Methodology ====
 According to EMEP (2023) the NH<sub>3</sub> emissions from crop residues can be neglected when the crop residues are on the field for less than three days. Thus the first step in the emission calculation is determining which share of the crop residues of each crop are incorporated into the soil or removed in the first three days after harvesting the crop. The remaining amounts are multiplied with their respective N contents and the resulting amounts of N are then multiplied with the NH<sub>3</sub>-emission factor. According to EMEP (2023) the NH<sub>3</sub> emissions from crop residues can be neglected when the crop residues are on the field for less than three days.

 According to the methodology given in EMEP (2023) the emission factor for the NH<sub>3</sub> emissions from crop residues applied to the soil is zero if the N content of the above ground crop residues is below or equal to the threshold of 0.0132 kg N per kg dry matter. In all other cases the NH<sub>3</sub> emission factor is determined using the following linear regression, see EMEP (2023): According to the methodology given in EMEP (2023) the emission factor for the NH<sub>3</sub> emissions from crop residues applied to the soil is zero if the N content of the above ground crop residues is below or equal to the threshold of 0.0132 kg N per kg dry matter.

-TSP and PM<sub>10</sub> are key sources. Emissions depend on the areas covered, crop types and number of crop operations. With the exception of the numbers of soil cultivations, which is slightly decreasing, these data are relatively constant. Overall this is reflected in a slight decline of emissions in the last 12 years. +TSP and PM<sub>10</sub> are key sources.
