Soil acidification associated with natural processes and neglect of maintenance liming has a negative impact not only on grassland productivity, but also on the soil's physical properties. Together with different methods of harvesting permanent grassland, the effects of amelioration liming on these properties were investigated. In a two-year experiment, changes in the values of physical and hydrophysical parameters were evaluated. These were determined from the sampling of soil samples in three periods (spring, summer, autumn). As a result, a positive effect of the application of dolomitic limestone at the dose of 3 t.ha-1 was found out to be increasing the soil reaction, reducing the bulk density, increasing the non-capillary porosity and increasing the minimum air capacity. In addition to the more stable structure, differences were observed among grassland management only in partial results. For example in non-limed variants was discovered the decrease of pH or increase in bulk density which was reduced as a result of mulching. There was as well confirmed positive effect of mulching on the increase of oxidizable carbon content or bulk density reduction.
