MapField

Targeted Nitrate Retention

The aim of the MapField project is to provide detailed knowledge of the near sub-surface with resolution on the meter scale. This is crucial for predicting the path, flow and transformation of water and nitrate from the individual field, and until the water and nitrate end up in groundwater or streams. The knowledge is intended to form a basis for future fertilizer-use legislation. Today we know that some areas has a natural ability for nitrate retention while others don’t, but we don’t have detailed knowledge of where these areas are, and hence the use of fertilizers cannot yet be adopted to the vulnerability of the individual field or part of a field. The highly interdisciplinary project brings together researchers working on geophysics, hydrogeology, geochemistry, agriculture, modelling, software development, economy and business development.
