Baltic Manure – The winner takes it all!
Press Release, October 2011
The Baltic Sea is a complex ecological system which suffers massively from anthropogenic actions. Particularly agriculture is one major contributor to its periodically occurring eutrophication. To promote a profitable, competitive and sustainable development of the Baltic Sea region, the EU Strategy for the Baltic Sea Region provides a framework for different projects to obtain funding from various sources and to focus actions in the key areas.
In September 2011, the 4th joint seminar of the EU Strategy for the Baltic Sea Region dealing with sustainable agriculture, forestry and fisheries took place in Helsinki. One of the flagship projects that were developed within the strategy is the EU-financed project Baltic Manure (http://www.balticmanure.eu). Scientists from the Institute for Crop and Soil Science (PB) (part of the Julius Kühn-Institut (JKI)) in Braunschweig are lead partners of the projects’ work package “Standardization of manure types with special emphasis on the phosphorus challenge”.
Within the seminar, JKI-PB prepared and lead a workshop entitled “Baltic Manure – the other BATMAN story” in which the project partners had the opportunity to present interesting facts and findings around phosphorus and manure in the Baltic Sea Region. To attract the full attention of the audience and to gain a participative character questions according to the quiz show “Who wants to be a Millionaire” were prepared. And the winner was definitively the audience.
Referring to the presentations, the chair of the workshop Prof. Dr. mult. Ewald Schnug concluded that the basis for a sustainable plant production and conservation of the finite resource P is a full utilisation which can be achieved by adding fertiliser P according to the amount that was removed from the soil by crops. In addition, P-recycling from P-rich waste materials (e.g. sewage sludge, manure, abattoir by-products) is desired but it is has to be ensured that the recycled fertiliser products contain no xenobiotics, or infectious pathogens. To meet this aim, mono-incineration of the raw materials with subsequent procedures is recommended to reduce or even remove the contained heavy metals and to gain a high P-availability. Additionally, the positive energetic contribution of the incineration to a post-nuclear energy concept needs to be considered.
In a nutshell, a closed P cycle which uses recycled P-rich organic secondary raw materials on a demand-driven basis will leave all as winners – the Baltic Sea Region as well as their inhabitants.
