In 2005-2009 the temporal and spatial dimensions in the six research sites were studied in order to assess the impact of environmental management on change of basic physical properties of the soil. Crop rotation was as follows: perennial fodder crops - perennial fodder crops - winter crops - root crops - spring crops - annual fodder crops. Soil sampling to determine bulk density, porosity and maximum capillary capacity was realised two times a year in spring and autumn at the six locations (I.-VI.) from the depth of 0.05 to 0.15 m. The results obtained were tested by statistical methods (analysis of variance, LSD-test). Soil bulk density is influenced by ecological farming in the five-year time series in comparison with 1996 and decreased its value in the interval ranging from 0.91 to 1.36 t m -3 in both samples. The porosity corresponded with bulk density, which in 2009 increased in all locations to the optimal levels for plant growth. The maximum capillary capacity in 1996 reached very low values (17.40 to 20.65%). In 2009 its value increased from 25.59 to 42.84%, which maybe associated with sum of precipitation and ecological farming, too. The positive change of soil bulk density and porosity and increasing the maximum capillary capacity was recorded in comparison with 1996. Test of obtained results confirmed a statistically significant effect of experimental year and localities on the bulk density, porosity and maximum capillary capacity. The date of sampling significantly influenced the values of porosity and the maximum capillary capacity.
