The influence of different vegetation covers of the set-aside land on the volumetric water content (VWC) and its variations during the day in upper soil layers (5 and 15 cm) was observed using the TDR method in 15 min intervals from May to August in 2002 and 2003. A spontaneous fallow was established in autumn 2001 and plots with artificial revegetation sowed with the mixture of Dactylis polygama and Trifolium repens in spring 2002. The experimental plots were mulched twice during the vegetation period. VWC was registered in the same time also on bare ground. The control plot was sown with Brassica napus - 2002 and Triticum aestivum - 2003 and regular tillage using ploughing was applied. The highest values of VWC were recorded on bare ground. The lowest values of VWC were recorded in 5 cm depth on plot sowed with the mixture of D. polygama and T. repens. VWC values on spontaneous fallow were lower in depth of 15 cm than in the 5 cm depth. The highest variation of daily VWC run was recorded on bare ground.
