This association includes weed vegetation of both cereal and root-crop cultures at higher altitudes and in precipitation-rich areas. In most places it occurs on loamy and heavy soils. It can also develop on wet soils in the lowlands and occasionally even outside agricultural habitats such as on alluvial deposits. Its phenological optimum is in summer, but it can persist on the stubble fields until autumn.
