There were presented the results of investigations of chosen physical proprieties of loamy sand on which winter barley was cultivated in technology of transit paths. Measurements were made separately for both topsail and subsoil layers within the zones of various intensity of affecting soil by driving road systems of combined machines i.e. at headlands, technological paths, as well as between adjacent technological paths. On the ground of conducted investigations it was stated that the soil being in zone of the transit paths as well as of the headland underwent the large degradation appearing with unfavourable changes of volumetric density, total porosity, moisture, compactness and shearing resistance.
