Non-invasive Observation of the Compacted Plough Pan Layer and Its Effect on Soil Water Regime

Popis výsledku v původním jazyce

A compaction of soils at agricultural areas is a known phenomenon influencing the water retention and runoff regimes. Nevertheless, an investigation of compacted soil layer position and (dis)continuity is complicated. Using of direct measurement methodsis almost infeasible at larger areas due to excessive labour and cost demands of such an approach. Other disadvantage of direct methods is usually lack of continuous information, which may be desirable in some cases. The electrical resistivity tomography(ERT) is useful method for its relatively simple and non-invasive data acquisition and continuity of the measured data. However, reliability of the ERT measurement for exact plough pan delineation is still questionable. In this work we assessed the feasibility of the ERT to delineate the compacted soil layer. To do so, we compared soil electrical resistivity with soil penetration resistance. The field experiments took place at the experimental catchment in central part of the Czech Repu
