The paper discusses possibilities and limitation of a sensor for dynamic characterization of soil microrelief, analyzing the metrological performance and the effect of the operating conditions on three-dimensional reconstuction. Data sets analysis is made on the basis of surface roughness parameters, as defined by ISO 25178 series. The paper demonstrates how proper calibration and instrument set-up procedures can improve the resolution down to millimeter level, even on relatively large areas. Practical application examples are reported with the result of measurements on soil after operations with different agricultural machines.

Abstract
The paper discusses possibilities and limitation of a sensor for dynamic characterization of soil microrelief, analyzing the metrological performance and the effect of the operating conditions on three-dimensional reconstuction. Data sets analysis is made on the basis of surface roughness parameters, as defined by ISO 25178 series. The paper demonstrates how proper calibration and instrument set-up procedures can improve the resolution down to millimeter level, even on relatively large areas. Practical application examples are reported with the result of measurements on soil after operations with different agricultural machines.
