Table 3 Means of volumetric water content (VWC), bulk density (BD), mean penetration resistance 0–20 cm below the surface of the soil (PR020) and thickness of humus layer (humus layer) by sub-columns. Each subcolumn includes 4 samples
From: Predicting rut depth induced by an 8-wheeled forwarder in fine-grained boreal forest soils
