Spatial analysis of subsoil compaction on cultivated land by means of penetrometry, electrical resistance tomography and X-ray computed tomography

Popis výsledku v původním jazyce

Soil compaction is a well recognized phenomena in the agricultural land. Various effects can alter the degree of the compaction in the field. The topsoil is regularly loosened due to agrotechnical operations, but the subsoil remains usually compacted. Various studies show increasing bulk density and decreasing saturated hydraulic conductivity in the plough pan, even though some authors argue that it does not have to be always the case due to presence of bio-macropores. Hence the structural properties ofthe subsoil and the spatial distribution of the compacted layer depth within the cultivated fields are important factors influencing soil water regime, nutrients regime and runoff generation. The aim is to present the results of the monitoring of the plough pan depth spatial distribution at the experimental catchment Nucice (Central Bohemia, Czech Republic) (Zumr et al., 2015). To observe the divide between topsoil and subsoil layers in detail and to be able to compare the soil structur
