Jeroen Buysse Faculty of Bioscience engineering – Department of Agricultural Economics KBBE.2011.1.4-06: Towards land management of tomorrow – Innovative forms of mixed farming for optimized use of energy and nutrients KBBE.2011.1.2-02: Reducing mineral fertilisers and chemicals use in agriculture by recycling treated organic waste as compost and bio-char products

7. Jeroen Buysse Faculty of Bioscience engineering – Department of Agricultural Economics Text of call: general objective  An important element of agricultural sustainability is to establish optimized flows of energy and nutrients with a high degree of recycling by transforming waste into resources such as fertilisers. In addition, optimizing the carbon cycle towards greenhouse gas mitigation is a new challenge for land managers.

8. Jeroen Buysse Faculty of Bioscience engineering – Department of Agricultural Economics Text of call: analysis of the problem  Modern specialised crop production systems rely on external inputs for feed and fertilisation, whilst specialised livestock systems face dramatic costs and problems in waste disposal. The profitability and importance of traditional mixed farming systems is drastically reduced because of pressure for specialisation, economies of scale and work load reduction.

9. Jeroen Buysse Faculty of Bioscience engineering – Department of Agricultural Economics What is a traditional mixed farming system?  Exchange and transport of manure exists already many centuries  Specialisation started since the abundance of subsistence farming and has continued ever since

12. Jeroen Buysse Faculty of Bioscience engineering – Department of Agricultural Economics Text of call: specific research objectives  develop new strategies to connect livestock and crop production at farm, district and landscape level  The project will evaluate new innovative ideas and develop new strategies to connect livestock and crop production at farm, district and landscape level in order to optimize energy, carbon and nutrient flows preserving natural resources and maximising production. In addition, diversified land use can open up new possibilities for combining food production with biomass production and on-farm production of renewable energy from livestock manure, small biotopes, perennial crops and semi-natural non-cultivated areas.

13. Jeroen Buysse Faculty of Bioscience engineering – Department of Agricultural Economics Text of call: research questions  socio-economic aspects of collaboration models and implementation potential  innovative forms of collaboration between farmers  test new combinations of agronomic practices and livestock practices

14. Jeroen Buysse Faculty of Bioscience engineering – Department of Agricultural Economics Text of call: methodology  A participatory approach in the identification and evaluation of the systems will allow immediate transfer possibilities and assessment of legal and organisational challenges.  Models will be applied at the various levels to predict productivity gains and economic viability of the mixed farming systems developed.
