Characterization and prediction of hydraulic properties of traffic-compacted forest soils based on soil information and traffic treatments

Table 2 Mean soil properties: clay and silt contents, USDA (US Department of Agriculture) classification system (Hartshorne and Dicken 1935) and HYPRES (European classification system) (Wösten et al. 1999) textural classes, soil organic carbon content (SOC), pH in water (1:5 in volume)
