Chernozem soil-type forms 11% of the agricultural land fund in the Czech Republic. It is located in the driest and warmest regions of the Czech Republic. It occurs up to an altitude of 300 m a. s. l. with an average annual temperature of 8 В°C and an annual precipitation of 450 - 650 mm.

Soil degradation is a global problem which is steadily growing. The consequences of soil degradation are environmental, economic and social. This work deals with degradation of physical properties of soil. The aim of the paper is to determine the effect of soil compaction on its retention. For this purpose, 16 plots with soil type cambisols were selected. Physical properties of eight plots are assessed as undegraded and eight as degraded. We focused mainly on bulk density and porosity as indicators of over-compact...
