    - Due to the new Fertilizing Ordinance (DÜV 2020), liquid manure (except for leachate) and poultry manure applied to uncultivated arable land must be incorporated within 1 hour. In addition, a decline in the prevalence of the "broad-cast" technology was projected (effect: approximately -15 kt NH<sub>3</sub> emissions).    - Due to the new Fertilizing Ordinance (DÜV 2020), liquid manure (except for leachate) and poultry manure applied to uncultivated arable land must be incorporated within 1 hour.

    - There are also slight differences in the new baseline in the forecasted number of animals and animal performance. Additionally, there were changes in the emission models (see previous IIRs). This strongly interacts with the previous point, so that it is not possible to determine a more specific reduction effect of the new Fertilizing Ordinance. (Overall, the effects of 3. and 4. add up to approx. - 16 kt NH<sub>3</sub> emissions.)    - There are also slight differences in the new baseline in the forecasted number of animals and animal performance.

 +Information on the underlying assumptions for projecting activity data is also provided in Thuenen-Report 84((Thuenen-Report 84 (2021): Calculations of gaseous and particulate emissions from German agriculture 1990 – 2019, Report on methods and data (RMD) Submission 2021, https://www.thuenen.de/media/publikationen/thuenen-report/Thuenen_Report_84.pdf)) on pages 74 to 75 in chapter 3.3.7 as well as in table 3.9. Although Thünen-Report 84 matches emission inventory submission 2021, the numbers in 2025 and 2030 are the same as used for the projections based on emission inventory submission 2020 described here. For all other data the activity data of the year 2018 are used with the exception of area and yield data for horticultural crops, strawberries, cereals for whole plant harvesting, yield data for grassland and the input data for liming. For these data the mean values for the years 2016 to 2018 were used.
  
 In total, according to the updated baseline, only 57 kt of NH<sub>3</sub> need to be additionally reduced by agriculture.   In total, according to the updated baseline, only 57 kt of NH<sub>3</sub> need to be additionally reduced by agriculture.
