Surplus of nutrients, in particular, phosphorus, in certain geographic regions due to increasing segregation of animal and crop production is a common problem across the Baltic Sea Region. Furthermore, mineral phosphorus reserves are a definite resource and are both subject to and driving social and political conflicts. The SuMaNu project (Sustainable Manure and Nutrient Management for reduction of nutrient loss in the Baltic Sea Region) promotes more sustainable use of nutrients, which in the long run is an absolute cornerstone of economic and ecological food production. Participating in the project provides BSAG with the opportunity to continue its international cooperation and is also a continuation of BSAG’s successful, decade-long work in the realm of nutrient recycling.
What can nutrient recycling look like at the farm level? SuMaNu visited Vierelä Farm in Vihti, Finland. Subtitles are currently available in English and Swedish. Make your selection in the player. (The project presentation continues below.)
SuMaNu, financed by Interreg, synthesizes the results from four recent projects that focused on manure and nutrients. The projects include Baltic Slurry Acidification in which BSAG participated in 2016–2019. Baltic Slurry Acidification investigated the mitigation of ammonia emissions from animal slurry using slurry acidification technologies. Manure Standards, as its name suggests, produced standardization of information on manure and digestate produced in different countries. The focus of GreenAgri was on farmers from Estonia and Latvia testing organic fertilisers and Bonus Promise researched the safety of recycled fertilisers.
The aim of SuMaNu is to analyse the results of the aforementioned projects and other agri-environmental projects in order to produce a holistic understanding of the ways in which nutrients can be used more sustainably in agriculture. SuMaNu produces summaries of best practices for farmers and policy recommendations for decision-makers in the entire Baltic Sea Region.
Natural Resources Institute Finland leads the project while BSAG is responsible for the communication. Other partners include HELCOM, Estonian Crop Research Institute, Union Farmers Parliament, Organe Institute, Agricultural Advisory Center in Brwinow, Julius-Kühn-Institut, and RISE Research Institutes of Sweden. The project began its work in October 2018 and continues until the end of March 2021. Visit the SuMaNu platform website.
