- | ====== Recalculations | + | 1) Dairy cows and calves: Adjustment of initial weight, energy requirements and feeding according to German expert recommendations; |
+ | 2) Heifers: Subdivision into dairy and slaughter heifers with different final weights; adaptation of energy requirements and feeding according to German expert recommendations. | ||
- | (see 8.1 Recalculations) | + | 3) Male beef cattle: Adjustment of feeding according to German expert recommendations; |
- | In the following, the most important reasons for recalculations are summarized. The need for recalculations arose from improvements in input data and methodologies (for details see Rösemann et al. (2021), Chapter 3.5.2 [1]). | + | 4) Male cattle > 2 years: update (increase) of the amount of bedding material (straw). |

- | 2. Dairy cows: Update of milk yields | + | 6) Sows: Update of the number of piglets per sow in 2018. |
- | 3. Dairy cows, heifers, male beef cattle: Update of weight data concerning the years 2016 and 2017 and (only for male beef cattle) also the year 1999. | + | 7) Fattening pigs and weaners: Update of animal numbers, starting weights |
- | 4. Suckler cows: Based on re-analysis | + | 8) All pigs except boars: Update |

- | 6. Pigs: In the case of air scrubbing systems in pig housings, a distinction between certified and non-certified systems has been introduced in accordance with improved data availability for Submission 2020: For certified systems, removal of NH3 and particulate matter is taken into account, while non-certified systems are assumed to only remove particulate matter reliably. | + | 10) Broilers: Update of the national gross production of broiler meat in 2018; update of activity data of air scrubbing systems in broiler |
- | 7. Laying hens and broilers: For the present submission 2020, air scrubbing in housings was taken into account for the first time as activity data is now available. | + | 11) Turkeys: Recalculation of the final weights of roosters and hens 1990 to 2001. |

- | 13. Application of sewage sludge to soils: Update of the activity data in 2017. | ||
- | 14. Starting with the present Submission 2020, the emission factors for spreading of liquid manure and anaerobically digested manure with trailing shoe on bare soil were updated; they are now assumed to be identical to the emission factors for spreading with trailing hose on bare soil. This was judged to be more realistic than the previous assumption of them being identical to those for trailing shoe on grassland. | ||
- | 15. The emissions of TSP and PM from agricultural soils differ slightly from the corresponding emissions in Submission 2019. These changes are due to the fact that for the first time the acreage of strawberries and cereals for whole plant harvesting were considered. The differences to the submission 2019 are between 0.05% (1990) and 1.1% (2015). | + | ==== Visual overview ==== |

Once emission calculations with the German inventory model GAS-EM are completed for a specific submission, activity data (AD) and implied emission factors (IEFs) are transferred to the CSE database (Central System of Emissions) to be used to calculate the respective emissions within the CSE. These CSE emission results are then cross-checked with the emission results obtained by GAS-EM. | Once emission calculations with the German inventory model GAS-EM are completed for a specific submission, activity data (AD) and implied emission factors (IEFs) are transferred to the CSE database (Central System of Emissions) to be used to calculate the respective emissions within the CSE.
