Sustainable Manure and Nutrient Management for reduction of nutrient l

Efficient manure and nutrient management in agriculture is beneficial for the environment and for the farmer and is a key aspect of ensuring sustainable food production for the future.

SuMaNu (Sustainable Manure and Nutrient Management for reduction of nutrient loss in the Baltic Sea Region) is a platform project which aims to analyse and synthesize approaches to sustainable manure and nutrient management promoted by four international projects. These are Interreg Baltic Sea Region projects Baltic Slurry Acidification and Manure Standards, Interreg Central Baltic project GreenAgri and BONUS Programme project BONUS PROMISE.

Towards regional and more holistic view

The SuMaNu synthesis of the solutions developed in the four projects will be used for formulating recommendations for environmentally and economically sustainable manure management in order to better link project results and policies. SuMaNu will target this information nationally and internationally especially to policy-makers. Communication will also be directed to other stakeholders, in particular, to farmers via farmers’ unions and advisory services.

Representation across the Baltic Sea

SuMaNu partners come from different Baltic Sea countries, Finland, Estonia, Latvia, Germany, Poland, Denmark and Sweden and includes the  intergovernmental organisation HELCOM – Baltic Marine Environment Protection Commission.

Project results

Technologies and management practices for sustainable manure use in the Baltic Sea Region by Erik Sindhöj, Marek Krysztoforski, Katrin Kuka, Sari Luostarinen, Zanda Melnalksne, Kristina Mjöfors, Kaisa Riiko, Kalvi Tamm, Kari Ylivainio, Minna Sarvi

The objective of this report was to compile recommendations from seven previous Interreg and Bonus projects dealing with improving manure use in the Baltic Sea Region. The recommendations were sorted according to where along the manure handling chain they should be implemented and synthesized in terms of the various aspects of sustainability they aimed at improving.

Manure processing as a pathway to enhanced nutrient recycling by Sari Luostarinen, Elina Tampio, Johanna Laakso, Minna Sarvi, Kari Ylivainio, Kaisa Riiko, Katrin Kuka, Elke Bloem and Erik Sindhöj

The need to introduce new nutrients into the current demand from mineral resources could be reduced significantly via nutrient recycling. The most significant recyclable material is animal manure which is traditionally used as a fertilizer. However, due to segregation of crop and animal production, manure is often regionally concentrated so that its nutrients may be available in excess to the region’s need. To enable regional nutrient reallocation, manure processing to various end-products could be used. In this report the advantages and challenges of manure processing are discussed and several processing technologies introduced.
