This association occurs both in warm and cool areas of the Czech Republic in root-crop fields, kitchen gardens or oil-seed rape cultures. It also occurs in cereal fields, especially at higher altitudes or where they are more frequently sprayed with herbicide. On some sites, particularly at lower altitudes, this community developed from other weed communities due to agricultural intensification. Soils are heavy, loamy or clayey, and base-rich. This association may develop already in spring, but its phenological optimum is in late summer.
