Description	Physical properties of soil and infiltration rate of water in crop stand and in wheel ruts of farm machines were evaluated in fields with registered wheel traffic of farm machines in wheel rows. A comparison of the rate of water infiltration under rainfall simulation at the constant intensity of rainfall 87 mmh-1 confirmed a negative influence of soil compaction in wheel ruts of machines. In the loam-sandy soil surface water runoff started 5 times sooner in wheel ruts than in crop stand. Light soils were able to infiltrate a fifteen-minute torrential rain at places outside wheel ruts. Only 30 to 40% of precipitation water was infiltrated at the same time in wheel ruts and the content of soil in runoff water was 4.9 times higher than in crop stand. On the heavy-textured sandy-clay soil cumulative surface water runoff after 60 minutes was 30% of the precipitation amount at places of wheel ruts, which was a fourfold value compared to surface water runoff at places outside wheel ruts.
