Field Instruments


Direct field measurements are necessary in order to characterize a specific location, taking into account real boundary conditions and heterogeneity such as those of the soil or vegetation. Key parameters in soil and soil hydrology include the (field) saturated hydraulic conductivity or the infiltration rate. The determination of the pneumatic conductivity is important for the description of the gas transport in soils. This may also be used for deriving the hydraulic conductivity.With innovative measurement techniques, It is now also possible to determine chemical parameters such as  the carbonate content, the electrical conductivity, and the pH-value easily and under real boundary conditions, which previously could only be determined in laboratory tests.
