Kurzfassung

Although most of Hungarian lowland landscapes show a flat geomorphology a very high diversity of soils developed. The most important reason of this diversity is the everywhere presence of small elevation differences due to controlling runoff and groundwater levels. In local level (southern Hortobágy) the typical elevation for developing accumulation horizons (86,5-87 meter above sea level), their intensity (ESP up to more than 70 %) and vertical position in profiles (closer than 50 cm to the surface) were established. With deviation (in both directions) from this surface level decreased the intense, and increased the vertical position of accumulation horizons. In the study area also strict human control on groundwater level was found, which could shift the accumulation horizons vertically. The process could reorganize of soil pattern also horizontally, also in larger scale.
