【 摘 要 】

This work analyses the problem of measuring water retention curves in heavy soils. The results present the differences between soil water retention curves measured in soil samples collected from the selected localities of the Czech and Slovak area. In the drying process, the results showed an increased rate of soil shrinkage depending on clay content and water content. The rate of shrinkage affected the results of the water retention curves points measurement.
