Purpose of research: Inventory & Assessment
In agricultural soils, high P contents and the excessive use of manures and fertilisers can result in diffuse P losses to surface and groundwater. High P concentrations in surface waters are known to be a major cause of eutrophicateion with negative impacts on water quality, since P usually is the nutrient that limits alge growth in freshwater (Correll, 1998, Buczko and Kuchenbuch, 2007). Nevertheless, phosphorus is an essential nutrient in the field of plant nutrition and since rockphosphate deposits are a finite, non-renewable resource, P recycling from secondary raw materials it is important to conserve this resource. Hence, a harmonised understanding of the properties of different manure types and their value as a fertiliser before and after processing is desirable and it is important to evaluate existent manure norms and establish new norms to ensure a safe and sustainable agriculatural use of untreated and treated manure in the Baltic Sea Region, especially with view to P recovery.
