   Temporal variability of soil propreties measured in surface horizons of three soil types (Haplic Cambisol, Greyic Phaeozem, Haplic Luvisol) was studied in years 2007, 2008, 2009 and 2010. Undisturbed soil samples were taken every month to evaluate the actual field soil-water content, buld density, porosity. The grab soil samples were taken every month to evaluate aggregate stability, pHH2O and pHKCl, soil organic matter and quality. The study showed different trends during different years. Our results showed that it tis impossible to aply any model, which would be based on statistical analyses, to predict soil properties development during one year or even long period. Results indicate that findings cannot be used to generalize soil propperties for other soil types, plants or climates.
