This species-rich weed association is rather common in warm areas at low altitudes. It occurs in cultures of winter and summer cereals, oil-seed rape, on fallows, stubbles and occasionally in root-crop fields. Soils are usually base-rich, but in some places this vegetation type also develops on slightly acidic soils. Its phenological optimum is from late spring to early summer.
