Overview of soil phosphorus data from a large international soil database

An overiew of extractable soil phosphorus (P-Bray, P-Olsen, P-Mehlich and P-water) and P-retention data held in a large profile database is presented. The primary aim is to assess whether representative P-values, by broad soil group (FAO system), can be determined for each of these analytical methods to support GIS-based assessments of food security.
The study was carried in the framework of the project “Resource scarcity and distribution in a changing world” (BO-10-011-007) of the (former) Ministry of LNV (Agriculture, Nature conservation and Food quality), implemented by the Business Unit Agrosystems Research (AGRO) of Plant Research International (PRI), Wageningen University and Research Centre.
