Selection of fields
To apply the PLAP-monitoring data directly in the regulation of pesticides in Denmark, the fields have been selected to represent the Danish soil types and climatic conditions. Additionally, the clayey till fields have been selected because they have a tile drain system installed at the latest in 1940 to minimise any artificial transport pathways to the groundwater from the surface of the field.
The map shows the annual net precipitation across Denmark and the location of the six PLAP fields. The PLAP fields are located so they represent the span in net precipitation observed in Denmark: Jyndevad, Estrup, Silstrup and Tylstrup in Jylland and Faardrup and Lund on Sjælland.
