Nitrates Directive Water Framework Directive Groundwater Directive
Nitrates Directive Water Framework Directive
MITERRA EUROPEA tool for integrated assessment of N emissions from agriculture at regional, country, and EU 27 levels
EmissionsGaseous: NH3, N2O, NOx, and CH4 Leaching of N to groundwater and surface waterNitrogen and phosphorus surpluses
Based on existing data bases and models (CAPRI and RAINS), supplemented with a new leaching module
Packages of measures to mitigate NH3 and NO3 emissions
Developed for the European Commission (DG Environment)http://ec.europa.eu/environment/air/cafe/activities/ammonia_en
Methods of calculation:Fertilizer and manure distribution: MITERRAN and P surplus: MITERRAEmission of NH3 and NOx: RAINSEmission of CH4 and N2O: GAINS/IPCCLeaching: MITERRA
Ammonia measures (from RAINS)
Low Nitrogen Fodder (dietary changes)Stable Adaptation by improved design/construction of floorCovered Manure StorageBiofiltration (air purification) Low Ammonia Application of ManureSubstitution of urea with ammonium nitrateIncineration of poultry manure
Parametrization + implementation: RAINS
Selected nitrate measures from Nitrate Directive
balanced N fertilizer application maximum manure N application rate no N application in winter and in wet periodslimitation to N application on slopesmanure storage with low risk of runoff and seepageappropriate N application techniqueswinter cropsbufferstrips near water courses
