Abstract
This study developed a field sampling and preparation method to obtain soil slices (7.5 by 20 by 3.5 cm, maximum seven parallel slices) with intact surfaces that allows analysis of surface properties and processes with high spatial resolution. In an example application, soil wetting properties (in terms of contact angle, CA) of sandy and loamy top- and subsoil slices were analyzed. Mapping of the CA (millimeter grid) revealed high variability (0–130°) for topsoil. Subsoil surfaces were wettable (0–5°), however, high CA (~70°) domains could be identified and associated with a textural boundary. Semivariances indicated higher heterogeneity and higher spatial correlation ranges for the topsoil. Results indicate that our approach allows the detection of small-scale variations and is a promising tool to analyze surface properties with high spatial resolution on parallel soil slices.
