This paper presents an analysis of soil moisture dynamics in the 2012 growing season at the experiment field of the Department for Organic Farming and Biodiversity, Institute of Field and Vegetable Crops. Soil moisture dynamics was monitored in plots under medicinal plants (marigold, mint and basil) grown by two production systems: conventional and organic. In the summer months (June, July and August), i.e., in the critical period for plant growth, high air temperatures, low air humidity, rainfall deficit, and frequent hot winds caused dry spells that varied in intensity. The rainfall during these months was insufficient to meet the total water requirements of the cultivated plants. The rainfall was significantly lower than the annual average (lower by 24.6% in June, by 93.2% in August). The combined effect of weather conditions increased the soil evapotranspiration. Consequently, in both growing systems, the readily available soil moisture was on the verge of accessibility in June and early July, while the level fell under the permanent wilting point in the second half July and in August.
