Abstract
The characteristic of communities developing in sandy stubble fields in the area of the Podlaski Przełom Bugu mesoregion is presented in the paper. The association Echinochloo-Setarietum was the most frequently noted and the most differentiated internally. Subassociations: Echinochloo-Setarietum scleranthetosum and Echinochloo-Setarietum typicum, as well as lower phytosociological units were distinguished in it. Phytocoenoses with Setaria pumila and Oxalis stricta were also common in the studied area. Small area patches of Digitarietum ischaemi were observed seldom and in the poorest habitats. On superficially excessively moistened soils, phytocoenoses from class Isoëto-Nanojuncetea, community Spergularia rubra-Hypericum humifusum and association Centunculo-Anthoceretum were noted.
