+ | Emissions occurring in the agricultural sector in Germany derive from manure management (NFR 3.B), agricultural soils (NFR 3.D) and agriculture other (NFR 3.I). | ||
+ | Germany did not allocate emissions to category field burning (NFR 3.F) (key note: NO), because burning of agricultural residues is prohibited by law (see Rösemann et al., 2021: ((Rösemann C., Haenel H-D., Vos C., Dämmgen U., Döring U., Wulf S., Eurich-Menden B., Freibauer A., Döhler H., Schreiner C., Osterburg B. & Fuß, R.

+ | ===== Recalculations and reasons ===== | ||

+ | |||
+ | (see [[general: | ||
+ | |||
+ | 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. (2021), Chapter 3.5.2). | ||
+ | |||
+ | 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. | ||
+ | |||
+ | 3) Male beef cattle: Adjustment of feeding according to German expert recommendations; | ||
+ | |||
+ | 4) Male cattle > 2 years: update (increase) of the amount of bedding material (straw). | ||
+ | |||
+ | 5) Cattle grazing: The NH< | ||
+ | |||
+ | 6) Sows: Update of the number of piglets per sow in 2018. | ||
+ | |||
+ | 7) Fattening pigs and weaners: Update of animal numbers, starting weights and final weights for 2018. | ||
+ | |||
+ | 8) All pigs except boars: Update of activity data of air scrubbing systems in pig housings from 2005 onwards. | ||
+ | |||
+ | 9) Sheep, laying hens, broilers, pullets: Update of the NH< | ||
+ | |||

+ | 13) Mineral fertilizers, | ||
+ | |||
+ | 14) Application of sewage sludge to soils: Update of activity data in 2018. | ||
+ | |||

+ | ===== Specific QA/QC procedures for the agriculture sector===== | ||
+ | |||
+ | Numerous input data were checked for errors resulting from erroneous transfer between data sources and the tabular database used for emission calculations. | ||
+ | The German IEFs and other data used for the emission calculations were compared with EMEP default values and data of other countries (see Rösemann et al. (2021)). | ||
+ | Changes of data and methodologies are documented in detail (see Rösemann et al. 2021, Chapter 3.5.2). | ||
+ | |||
+ | A comprehensive review of the emission calculations was carried out by comparisons with the results of Submission 2020 and by plausibility checks. | ||
+ | |||
+ | 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. | ||
+ | |||
+ | Model data have been verified in the context of a project by external experts (Zsolt Lengyel, Verico SCE). Results show that input data are consistent with other data sources (Eurostat, Statistisches Bundesamt / Federal Statistical Office) and that the performed calculations are consistently and correctly applied in line with the methodological requirements. | ||
