2. Reference area Proposed action
Currently: arable land, permanent crops, permanent grassland
Includes rough grazing, fallow arable land, other marginal/unfertilised areas..
How to define the reference area?
How to exclude production on excluded areas?
Proposed action
Eurostat circulates document (problem statement) (end 2011).
Results discussed in WG AEI 27/ and other appropriate fora
13-Jul-07
Name of the presentation

3. Livestock numbers Proposed action
Should represent average number of animals in year
Proposed action
Eurostat circulates document (problem statement) (beginning 2013)
Results discussed in WG AEI 2013 and other appropriate fora
13-Jul-07
Name of the presentation

4. Other organic fertilisers
Data unavailable or partly available
Proposed action
Other potential data sources: European Composting Network
Improve data availability Sewage Sludge Directive
13-Jul-07
Name of the presentation

5. Manure exports and imports
Manure export and import significant only in a few regions an countries
Proposed action
Check with other data sources (GHG Inventory)
Check with modelling
MS responsibility
Regional level: modelling, MS data

Name of the presentation

6. Manure withdrawals and stocks
Manure processing
Data very limited available, not significant
Not clear of correction has been made for re-application of treated manure to agricultural soils
Inventory Manure processing Activities Europe (DG ENV, 2011)
0%-29% of livestock production
Growing importance
Not all manure processing and treatment leads to nutrient losses
Proposed action
Drop change in stocks
Non-agricultural use only accepted with sufficient proof
13-Jul-07
Name of the presentation

7. Biological Fixation Proposed action
Limited data available (secondary crops)
Grasslands (pure vs mixed with legumes, effect of fertilisation and grazing)
UNFCCC GHG reporting
Coefficients and methodologies vary
Proposed action
TF experts + statisticians with project Legumes Futures
(end 2013/beginning 2014).
Drop free living organisms
13-Jul-07
Name of the presentation

8. Atmospheric deposition (1)
Data on P limited available, not significant
Eurostat/OECD Nitrogen Handbook
In estimation of Surplus, no deduction is made for NH3 (and NOx) emissions double-counting (Italic terms) in Surplus
N-NH3 (N-NOx) from agriculture = deposited domestically (agricultural land + non-agricultural land) + exported to other countries + remaining in the air
Atmospheric N deposition agricultural land = N-deposits from non-agricultural sector+ N-deposits from agriculture (produced domestically + imported)
Correct total N deposits for N-deposits from domestic agriculture
13-Jul-07
Name of the presentation

9. Atmospheric deposition (2)
In fact no double counting, so no correction on N deposition necessary
N deposition is true input to soil
GNS = aGNS + hGNS
N emissions are true part of surplus
Proposed action
Drop P deposition
Change handbook guideline: no correction to N deposition
Use EMEP data: total N deposition/total land area * reference area
13-Jul-07
Name of the presentation

10. Seeds and planting materials
Data limited available, not very significant
Proposed action
a) Drop
b) Improve
Few crops with high contributions (e.g. potatoes)
Establish default nutrient values
MS: seeding rates
13-Jul-07
Name of the presentation

11. Crop residuals returned to soil
Available from GHG Inventory
Crop residuals burned do not have to be estimated
Proposed action
Include at input side
Establish default values (research project)
13-Jul-07
Name of the presentation

12. Crop production + by-products
Crop data available at NUTS0 and partly at NUTS2
Crop coefficients lacking/outdated. Comparability
Proposed action
Grants crop coefficients
Review with other MS data and other studies, inputs
Can include estimation of by-products and coefficients of by-products
TF 2012/2013 regional crop production data
TF 2012/2013 by-products + default values
13-Jul-07
Name of the presentation

13. Discussion points I Do you agree to drop from the balance estimations?
Change in manure stocks
Biological fixation by free living organisms
Atmospheric P deposition
Seed and planting material
Do you agree to include in the balance estimations?
Crop residuals returned to soil
Total N deposition (no correction)
N emissions
13-Jul-07
Name of the presentation

14. Discussion points II How can the reference area be identified?
Is it necessary to collect data on industrial waste and other organic products, or can it be considered negligible?
Do you agree with modelling transports of manure to verify MS data?
Should data on manure treatment and processing be collected? How?
Do you agree to use EMEP data for N depostion?
Are data on crop residuals incl coefficients sufficient available?
Are data on crop production sufficiently available at regional level?
Do you agree with the proposed actions?
