Abstract – The aim of our study was the investigation of the physical and chemical characteristics
of soils of Sopron. Based on our results the physical assortment of the samples was
highly clay in 6% of the samples. The pH measurements show that the deeper soil layers
belong to the slightly high class. 25% of the samples does not contain calcium-carbonate,
but calcium-carbonate has been found in the majority of the samples in the city center.
The upper layers of the soils in Sopron are rich in humus. Especially in the forest soils in
the South-western part of the city (next to the TV tower), we detected higher humus and
nitrogen values but these values are typically smaller in the deeper soil layer. For the ALsolvent
potassium, the lowest values have been measured in the area of the city. We found
extremely high values of AL-solvent phosphorus, of KCl-solvent calcium and magnesium
in the traffi c zones, as well as near to the agricultural area. The highest values have been
detected in the Sopron-hills, also in the case of iron. The manganese contents follow the
tendencies of the iron values in most of the samples. In both soil layers the higher zinc content
have been found in the downtown area, especially near to the busy roads in the center
and near to the bus station. The copper content was high in the Virágvölgy and the suburban
district of the town.

Abstract – In our investigation the chemical and physical characteristics of diff erent soil
types have been analysed in Székesfehérvár and in its surroundings. In spring-summer
2011 we collected 288 samples on 144 points from two soil layers (in 0-10 and 10-20
cm depths). Based on our results it can be concluded, that the soils are mostly alkaline,
and the calcium-carbonate content is high mainly in the city. The acidity and calciumcarbonate
content of soils are determined fundamentally by the parent material and the
calcareous deposited debris. Based on the particle size distribution and the Arany-type
compactness analysis, most of the samples are loamy textured soils. The physical assortments
show a heterogeneous picture in the city area, which refer to the soil types with different
deposition. The upper soil layer is well supplied with nitrogen. It can be explained
by the artifi cial fertilizer applied in this agricultural area and the human activity in the
city region. The soil of the surrounding agricultural territory is in the most cases less humic.
The possible reason of this is the intensive agricultural cultivation in this region.
The agricultural area shows generally very high phosphorus values, which is probably resulted
from the anthropogenic phosphorus fertilization. We detected the highest iron and
manganese contents in the Csalai forest, which is situated in the northeast direction from
the town. These high iron and manganese values refer to mineral origin. In both layers the
highest copper values have been detected in the Máriavölgy street along the main road in
suburban district. Salient zinc values have been found in Szárazrét (western part of the
town), from the industrial area along the railway line, where an iron-foundry industry
