-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.

 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.

-There are no recalculations because this source is reported the first time.+For all years, NH<sub>3</sub> emissions from crop residues are slightly higher than those of last year's submission. The main reason for this is **recalculation No. 15** (update of number of grassland cuts). Further details on recalculations are described in Vos et al. (2026), Chapter 1.3.

-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.

- +There were no recalculations. Further details on recalculations are described in Vos et al. (2026), Chapter 1.3. 
-For all years, totals of TSP, PM<sub>10</sub> and PM<sub>2.5</sub> emissions are higher than those of last year’s submission. This is mostly due to the introduction of cover crops to the calculation method (see main page of the agricultural sector, list of recalculations, No. 2).
