The conservation of soil and its elemental feature, tudhe soil fertility has not just national and udagricultural business interest, since the fertile soil is udan elemental part of the material turnover in the udenvironment. The soil erosion can reach huge spatial eudxtensions and starts with the most valuable part: the udupper, fertile layer. So, its research is crucial forud our future survival. Our studied area can be found udin udGerézdpuszta at the Koppányud-valley of Hungary, which is a sensitive erosion area.ud We sampled the upper 30 udcm of soil layer in every 10 meters that resulted 32-32 udpoint samples on the arable and on the grassland, udrespectively. One sample was taken under the forest as rudeference. We analyzed the basic soil parameters: udCaCOud3ud, pH, AL-Pud2udOud5ud, AL-Kud2udO, Kuron’s higroscopicity, SOM and the particle size diudstribution was uddetermined. Besides, we examined the connection between udthe given results from laboratory soil analyses and udthe Munsell-type and Google Earth satellite image colors. Oudur results show the erosion dynamic on our udsample slope, and the main differences in basic soil parametuders between different intensities. The main udindicator of soil erosion dynamic were the CaCOud3ud, the SOM, AL-Pud2udOud5ud and the particle size distribution, udwhere the SOM and CaCOud3ud were correlate with the Munsell and Google Earth coludor also.
