| Popis: | The soil cover of the Vladimir Opole was investigated by the method of long (up to 40–50 meters long and 1.5 m deep) transects. Four Qualifiers of Phaeozem (PH) were morphologically identified: albic, gleyic densic, grayzemic and PH cambic with the 2nd humus horizon. Agrophysical studies of soils in transects included layer-by-layer determination (every 20–40 cm along the trench, and at depths 0, 20, 40, 60 and 100 cm) of soil density, water permeability, and penetration resistance. The soil compaction (up to 1.57 g cm−3) was observed, which was especially pronounced in a layer of 20–25 cm and connected with the agrotechnological impact. Simultaneously, friable (−3) and, therefore, zones with high moisture capacity confined to PH with 2nd humus horizon, showing that the change in agrophysical properties in the soil cover occurs gradually, continuously and regularly and is determined by both pedogenetic and agrotechnological factors. |
