The conservation of soil and its elemental feature, t
he soil fertility has not just national and
agricultural business interest, since the fertile soil is
an elemental part of the material turnover in the
environment. The soil erosion can reach huge spatial e
xtensions and starts with the most valuable part: the
upper, fertile layer. So, its research is crucial for
our future survival. Our studied area can be found
in
Gerézdpuszta at the Koppány
-valley of Hungary, which is a sensitive erosion area.
We sampled the upper 30
cm of soil layer in every 10 meters that resulted 32-32
point samples on the arable and on the grassland,
respectively. One sample was taken under the forest as r
eference. We analyzed the basic soil parameters:
CaCO
3
, pH, AL-P
2
O
5
, AL-K
2
O, Kuron’s higroscopicity, SOM and the particle size di
stribution was
determined. Besides, we examined the connection between
the given results from laboratory soil analyses and
the Munsell-type and Google Earth satellite image colors. O
ur results show the erosion dynamic on our
sample slope, and the main differences in basic soil paramet
ers between different intensities. The main
indicator of soil erosion dynamic were the CaCO
3
, the SOM, AL-P
2
O
5
and the particle size distribution,
where the SOM and CaCO

were correlate with the Munsell and Google Earth col
