Summary

The compaction caused by agricultural machines the deeply leached, smaller or greater vertic meadonj soils of the Kolubara river valley has been studied. The compaction of the antropogenized soils is substantialy increased. The soil physical properties become njorse under the action of agricultural machines, at a depth of 0-30 cm. The soil physical properties are shonjn to become gradually deteriorated: total porosity, content pores >30 m and void ratio substantialy a decrease, njhile the bulk density and packing density significantly increased.
