Undisturbed and disturbed soil samples were taken every month to evaluate bulk density, porosity, ration of gravitational and capillary pores, pHKCl and pHH2O, organic matter content and its quality, aggregate stability using WSA index and micromorphological features. Results showed that soil aggregate stability depended on the stage of the root zone development, soil management and climatic conditions. Larger aggregate stabilities and also larger ranges of measure values were obtained in the year 2007. Aggregate stability reflected aggregate structure and soil pore development, which was documented on micromorphological images and evaluated using the ration of gravitational and capillary pores measured on the undisturbed soil samples.
