Sustainable Use of Phosphorus. The contribution covers the issue ofdwindling rock phosphate resources recommending enhanced P-recyclingfrom secondary raw materials (e.g. sewage sludge, manure, meat and bonemeal). Further the communication emphasize more focus should be put onassessing crop and soil specific P levels that are actually needed forgaining good yields so that over-use can be avoided and P can bedirected to fields with P response.
The project recommends separation of slurry in animal dense areasto move the P- rich solid part to areas with P deficiency and advocatefor the use of suitable precision farming technologies.
The regulation of a fertiliser application basing on the amountof (available) P in the soil would affect areas with high livestockdensity and require the export of manure (or manure solids) from theseareas to regions with a low livestock density. In this case theseparation of manure would be a convenient measure.
