Combined field and model-based approaches for large scale sustainable phosphorus management

Summary

An appropriate sustainable P fertilization strategy, ensuring enough l P supply for plant growth while avoiding environmental risk due to elevated P losses to surface waters is important for both farmers and society. This project contributes to enhanced understanding how crop P uptake is controlled by soil P pools, P inputs and soil properties affecting P buffering processes. Results of the response of soil P pools to P inputs and their supply potential to crops will be used to illustrate how sustainable P management in agriculture can be achieve at local and regional scale.
