This association includes species-poor stands of summer annuals dominated by Chenopodium glaucum and C. rubrum. It occurs on wet soils around barns, dung hills, depressions along puddles in villages, in places with agricultural waste water input, and on the exposed bottoms of nutrient-rich fishponds. In the past this kind of vegetation also occurred in saline pastures. This moderately thermophilous community occurs across lowland and colline areas of the Czech Republic.
