Kampf gegen das Algenwachstum im Eixendorfer Stausee

Es ist eine vielschichtige Aufgabe, der sich die Initiative "boden:ständig" stellt. Mit etlichen Mosaiksteinen möchte sie im Kampf gegen das Algenwachstum den Phosphateintrag in den Eixendorfer Stausee eindämmen.

Mit dem Entnahmeturm alleine ist es nicht getan. Auch der Phosphateintrag im Umfeld des Eixendorfer Stausees muss reduziert werden.
