Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers. Forinstance the limited economical life-span of phosphorus rock might lead to globalconsequences such as unequal distribution of the fertilizers which can increase thehunger around the world.In this thesis, laws, taxes, policies and technology that affect the management of plantnutrients have been described to show how the issue is handled today. Interviewswith representatives of some of the organizations whose activities directly, orindirectly, affect the flow of nutrients through the region of Stockholm have also beencarried out to better understand their views on responsibility and today's situation ingeneral.
