A study of the filter properties of soils in relation to water and air in the manor park in Kozłówka in the Lublin Province was carried out. The natural soils of the area are represented mainly by black soils formed from loamy sand. The soils of the park show significant differences from the natural soil cover, as they have been subjected to radical anthropogenic impacts as a result of various works associated with the construction and redevelopment of the palace buildings and the change of land use. As a result, there are now soils within the park that are classified as Anthrosols or Technosols. In all the studied pedons, the natural genetic horizons were obliterated, in some layers there was a change in the texture. The positive effect of anthropogenisation was mainly manifested in the high organic carbon content of the surface layer of all pedons. To analyse the filter properties of the soils, samples of preserved structure were taken from layers 0–10 cm, 20–30 cm and 40–50 cm into standard cylinders. The following properties were determined: the water filtration coefficient in the saturated zone (Ks); the water permeability; the air permeability at water potential states in the range -0.98 kPa to -49.00 kPa; the full water capacity and the air capacity. Considering the area of the entire park, it must be said that the filtration properties showed high levels in relation to both water and air. The water permeability was characterised by very high values. Also for air permeability in the field water capacity condition, very high and high values predominated. Particularly high values of this trait were found in the surface layer, rich in organic carbon. The presence of construction debris in large quantities in Urbic Technosols had the effect of reducing air permeability. The results obtained from the study of the filtering properties of the soils of the manor park in Kozłówka can provide an essential source of information which is the basis for undertaking possible recultivation and care works, which are necessary for the conscious shaping of the park establishment.
