Division Title of the action: Scale dependent nutrient bala

EU contribution: EUR 49 000

Schedule for the work: January-December 2007

Short description of the action:

To calculate balances in the highest possible spatial resolution for which the data are available to spatially differentiate and evaluate nutrient contamination risks, because a balance surplus on a national scale does not allow statements related to regions or farming systems where reduction measures are required. Balance sheets have to be specified particularly for risk areas.

Derivation of nutrient concentrations depending on land use intensity, specification of coefficients to convert livestock numbers into N amounts of excreta (output-related), application rates of inorganic fertilisers for different crops instead of sales figures, application rates and nutrient contents of organic fertilisers and adaptation of the existing OECD nutrient balances.
