Undisturbed and disturbed soil samples were taken every month to evaluate different soil properties. In addition, micromorphological features of soil aggregates were studied in thin soil sections. Results show that the soil properties varied within the time. Aggregate stability and values of the soil properties were influenced by the climatic factors, biology activity, growth of plant roots and soil management. Values of pH slightly varied within both years at all localities. Organic matter content and aggregate stability varied significantly during the first year. However, variability of those properties was considerably lower during the second year at all localities. Porosity and soil hydraulic properties were also more variable during the first year than during the second year.
