Prototype model for the phosphorus turnover in soils (P-Engine) in relation to varying environmental conditions in the Baltic Sea Region

One important precondition to close anthropogenic P-cycles and to reduce undesired nutrient inputs into the Baltic Sea is the complete utilisation of fertiliser P applied to agricultural soils.

Within this report, the importance of the consideration of P-utilisation rates and the relation between utilisation rate and optimum fertilisation rates to meet a balanced P-application is underlined. To show to what extent different fertiliser strategies and fertiliser rates have an effect on the pool of available P in the soil, the outcomes of four long-time fertiliser experiments were presented.

This report on the P-engine was prepared as part of workpackage 4 on Standardisation of Manure Types with Focus on Phosphorus within the framework of the EU-project Baltic Manure.
