Zusammenfassung

To date, large areas of farmland are fertilized without knowledge of the actual state of the soil which causes overfertilization and nitrate pollution of the groundwater. Electrical impedance spectroscopy (EIS) lends itself to the in-situ characterization of the composition of materials. Different material systems can be classified based on characteristic features of the impedance spectra. However, it is not at all clear if one can also extract quantitative information on species concentrations outside controlled laboratory environments. Soils resemble mixtures of sand, clay, and organ...
