Original title: Åtgärder mot fosforläckage från jordbruksmark – dikesfilter och dikesdammar; fas 2

The project ” Ditch dams and filters to trap phosphorus in agriculture” (2009-2013) aimed to bind phosphorus leaching from agricultural soil in ditches close to the original source, thereby reducing the discharge of phosphorus to the sea. The project, which consisted of two phases, has been evaluating three different lime-based filter materials (Polonite, Filtralite P and Hyttsand) on location in the south of Sweden, Poland and the Baltic. The results show that all the tested filter materials separate phosphorus from drain off water, with result variations depending on location. Read the full report by clicking on the link below.

Our focus areas

fisheryThe stock of predatory fish is crucial for the state of the Baltic Sea. Therefore, the Foundation worked to ensure that the environmental effects of fishing should be a central part of the EU's Common Fisheries Policy. The Foundation also worked on projects to increase the proportion of predatory fish, such as cod, pike and perch. Read more

eutroEutrophication is caused by emissions of nutrients that come from e.g. agriculture, water treatment plants, sewage and transportation. To find measures that could reduce emissions the Foundation worked on projects in agriculture, industrial animal farms and the coastal zone, to research on measures to catch or bind nutrients. Read more

seagull-informationTo create awareness about the threats and opportunities the Baltic Sea is facing, the Foundation initiated a 10-year media and film project with journalist Folke Rydén and photographer Mattias Klum. The Foundation has also supported Stockholm University Baltic Sea Centre (Baltic Eye), and Baltic Sea Science Center at Skansen. Read more
