  1. Mitigation Measures for Runoff Presentation and discussion Julie Maillet - Mezeray ARVALIS – Institut du végétal EU Stakeholder Workshop, 26 th April 2012, Brussels

  2. Aims of the session • Discuss and agree on runoff mitigation measures • Collectsuggestions / commentson implementation of proposedmeasures • Addnew measures if needed

  3. RunoffMitigationMeasures Mitigationmeasuretoolbox: Soil management • Reducetillageintensity • Manage tramlines • Prepareroughseedbed • Establish in-fieldbunds • Manage surfacesoilcompaction • Manage subsoilcompaction • Do contourtilling/disking Cropping practices • UseCroprotation • Do stripcropping • Use annual cover crops • Use perennial cover crops Vegetative buffers • Use in-fieldbuffers • Establishtalwegbuffers • Useriparianbuffers • Useedge-of-fieldbuffers • Manage fieldaccessareas • Establishhedges • Establish/maintainwoodlands Retention structures • Use edge-of-field bunds • Establish vegetated ditches • Establish Retention ponds/artificial wetlands Adapted use of pesticides • Adapt application timing • Optimize seasonal timing • Adapt product and rate selection Optimized irrigation • Adapt irrigation technique • Optimize irrigation timing and rate
