In the Staatsblad 2005 645, the Uitvoeringsbesluit Meststoffenwet has been published, with the soil type map as an appendix. On this map, all parcels in the Netherlands are classified according to the soil types sand, loss, clay and peat. The permitted use of fertilizers depends on the soil type. Water courses with fertilizer-free zones are also indicated on this map. In this project, the management and maintenance of the soil type map is guaranteed.
