-The following list summarizes the most important reasons for recalculations. Recalculations result from improvements in input data and methodologies (for details see Rösemann et al. (2025), Chapter 1.3).  +The following list summarizes the most important reasons for recalculations.

- +  -  Mineral fertilizers: The NH3 emission factors for mineral fertilizers in EMEP (2023) were used for the first time in the present submission. 
-   +  -  Crop residues: NH3 emissions from crop residues are calculated for the first time according to the tier 2 method from EMEP (2023). To facilitate this, cover crops are now included in the inventory data. Cover crops are also a newly reported source of PM emissions from soils.

   -  Horses: The animal numbers were corrected in all years and all districts by a factor of 2.75 to include horses which are kept outside of agricultural holdings and not counted by agricultural census. All horses are reported under 3.B as permitted by EMEP (2023) Section 4.2.    -  Horses: The animal numbers were corrected in all years and all districts by a factor of 2.75 to include horses which are kept outside of agricultural holdings and not counted by agricultural census.

   -  Transformation processes in storage: The previous assumption for untreated slurry that 10 % of the TAN entering storage is converted to Norg (immobilization) was dropped because no sufficient scientific evidence could be found for this.   -  Transformation processes in storage: The previous assumption for untreated slurry that 10 % of the TAN entering storage is converted to Norg (immobilization) was dropped because no sufficient scientific evidence could be found for this.
