3 Water catchment area „Schlei“
• Schlei > 42 km length; catchment area approx. 70.000 ha • 1 Federal Waterways and Shipping Office • Adminstrative levels: 2 districts and over 60 rural municipalities • 20 water and ground associations (maintaining water bodies) • 3 regional farmer associations
4 The unique history of the „Schlei“
UNESCO World Heritage : Haithabu & Danewerk Historic trading route : Baltic & North Sea Territorial changes: Danish-Prussian War in 1864 Different (agrarian) history: North ( Angeln ) & South ( Schwansen )
5 EU Water Framework Directive Thematic map to the 2nd WFD management plan Ecological status for lakes & coastal waters
very good good moderate unsatisfactory bad not classified
Other EU-Regulations: Natura 2000 network (Habitats and Birds Directives) Marine Strategy Framework Directive + HELCOM Local working groups (mainly in honorary office): WG - Water Framework Directive • Natura 2000 advisory board
6 Agriculture – the key issue • Different agricultural structures in the North (Angeln) and South (Schwansen) of the Schlei fjord • Catchment area: 79 % agricultural land mainly high productive arable land • Main crop ranking: 1. Winter wheat 2. Silage maize 3. Winter oilseed rape 4. Winter barley
* Catchment Area ** Entire characteristic landscape area in Schleswig-Holstein Data: agricultural structure survey 2016 (Statistical office North Germany)
7 Biogas production
Landscape changes: increase of biogas plants 1990 - 2013
Increase of biogas plants per km² 0 – 0,1 0,1 – 0,5 0,5 – 1,8
Increase of installed electric power (kW/km²) 0 – 48 kW 48 – 88 kW 88 – 784 no changes without biogas plants MELUND Landschaftsrahmenplan 2019 In the north-eastern part of Schleswig-Holstein > 200 biogas plants with more than 180.000 kW installed electrical power Bundesnetzagentur 2014
8 Farm-gate nutrient balances
Phosphorus Nitrogen
Henning & Taube 2020
9 Pathways of phosphorus Pathways of phosphorus of the river basin districts in Schleswig Holstein
Run off Erosion Interflow Ground water Drainages Deposition Sewage separation Small wastewater treatment plants Industry Large wastewater treatment plants
Tetzlaff et al. 2016 Risk due to water erosion : medium to very high landscape: glacial carved, slightly hilly
Nutrient availability in the upper soil: predominantly high to very high
10 Nutrient inputs
Schlei fjord low freshwater inflow few water exchange with the open sea
River system „Füsinger Au“ drains over 55 % of the catchment area

21 Water protection advice for farmers
area of advicing activities
LLUR 2019 Established since 2019 Supports the fertilizer management and crop rotation planning focusing also the new fertiliser ordinance (2020) in germany Funded by EAFRD & the federal state of Schleswig-Holstein
22 Temporary buffer strips
• New agri-environmental measure for Schleswig-Holstein • Temporary flowering buffer strips along water bodies • On arable land over 3 years 850 € / (ha*a) • Buffer strips > 10 m • Regional seed mixtures with rare species • No pesticides and fertiliser allowed
Funded by the federal state of Schleswig-Holstein

23 Temporary buffer strips
• High willingness to participate offering > 80 fields in 2020 priorization for 24 ha
• Farmers have mainly shown little experience with agri-envrionmental measures
• Support of the regional biotope network
24 Permanent buffer strips
• Purchase or long-term lease of buffer strips along all water bodies; payment of land market value • Obligation to maintain permant grassland • No pesticides, fertiliser and soil cultivation • Leaseholder/owner: Water and ground associations
Funded by the federal state of Schleswig-Holstein
