Subtitle: PhD Report 4
Description(s):Abstract: Water availability is a limiting factor for biological processes. As could be seen during the measurement campaign, the test site, which is known to have different subsurface composition, showed different water availability status in and outside the paleochannel system. Accordingly, different plant growing conditions also occurred during the vegetation period (April – October, 2016) of the sugar beets. To describe such differences in terms of the soil water, soil hydraulic properties like the Mualem-van Genuchten (MvG) parameters are used. Nevertheless, measured MvG parameters, and especially the saturated conductivity (Ks), show some weaknesses in stony soils. Therefore, the current methodology additionally applies an inversion of the MvG parameters, which are calibrated against the soil water content measured by SoilNet sensors at 18 locations in three depths (i.e., 10, 20, and 50 cm). First inversions were performed with the SIMPLEX algorithm while future inversions are planned to be performed by SCE-UA. The MvG parameters are going to be used to set up the final soil hydraulic model for upcoming ecosystem modeling with AgroC.
