Analysis of plant communities accompanying root crops on compact soils is presented in the paper. It is the next part of the review of plant communities of agrocenoses of the Podlaski Przełom Bugu (Podlasie Bug Gorge) mesoregion. The studied phytocoenoses were identified on the basis of 103 phytosociological relevés, made according to the Braun-Blanquet method. In the studied agrocenoses, plots of the associations Lamio-Veronicetum politae, Galinsogo-Setarietum and Oxalido-Chenopodietum polyspermi from the Polygono-Chenopodion polyspermi alliance were noted. Small patches of Lamio-Veronicetum and Oxalido-Chenopodietum were rarely noted in the studied area due to a small proportion of suitable habitats. In the area of Podlaski Przełom Bugu mesoregion, phytocoenoses of Oxalido-Chenopodietum developed in the river valleys on fertile muds and black soils. Typical plots of Galinsogo-Setarietum distinguishable by the mass occurrence of Galinsoga parviflora were only observed in the vicinity of farm buildings. Intermediate communities between Panico- Setarion and Polygono-Chenopodion polyspermi as well as phytocoenoces of Echinochloo-Setarietum typicum – subvariant with Veronica persica and Echinochloo-Setarietum fumarietosum – were also quite frequently noted in root crops on compact soils.

Studies on segetal flora of the "Podlaski Przełom Bugu" Landscape Park were carried out between 1994 and 1998 on the area of 110 localities situated in 16 communes. The list of segetal flora of the area under study and its differentiation as to occurrence frequency, origin of species, persistence of species and biological spectrum is presented in the paper. The segetal flora of the "Podlaski Przełom Bugu" Landscape Park is composed of 346 taxa belonging to 39 families and 193 genera. The dominant group are species occurring very rare, rare and fairly rare. In analyzed flora apophytes prevail (65,3 %) over antropophytes (34,7 %) and annual and biennial species (56,4 %) over perennial species (43,6 %). As to biological spectrum of the studied flora 52,5 % of total number of species are terophytes, 52,3 % hemicryptophytes and 11,0 % geophytes. 39 species threatened extinction in Poland were found in agrocenosis of "Podlaski Przełom Bugu" Landscape Park. Some of them occur frequently or commonly in the studied area, others are rare in cultivation and most frequently occur in adjacent natural communities. Among segetal flora of the studied mesoregion 7 species are actuaIly endangered extinction: Valerianella dentata, Melampyrum arvense, Pnlycnemum ar vense , Herniaria hirsuta, Camelina sativa, Stachys annua, Spergula arvensis subsp. maxima.

Studies on flora of fallow lands of the Podlaski Przełom Bugu mesoregion were carried out between 2001 and 2003 in the area of 77 localities, situated in 20 communes. A systematic list of fallow land flora was made and its variation with respect to occurrence frequency, biological spectrum, persistence and belonging to geographic-historical and sociological-ecological groups was analyzed. Flora of fallow lands of the Podlaski Przełom Bugu mesoregion includes 442 species included in 60 families and 241 botanical genera. The most numerous group comprises very rare, rare and quite frequent species. In the floristic composition of the analysed flora, apophytes (72.2%) predominate over anthropophytes (2.8%) as well as perennials (61%) over ephemerals (39%). Considering the biological spectrum of flora, hemicryptophytes (49%) and terophytes (32%) predominate over other life forms. Forest and shrub species (18.5%) as well as meadow (17%) and xerothermic sward plants (17.4%) have the largest share in the flora. The abundant occurrence of segetal (15.8%) and long-lived ruderal communities (8.1%) was also noted. Moreover, the occurrence of 25 species endangered with extinction in fallow land communities of the Południowopodlaska Lowland was noted. They are as follows: Nigella arvensis, Potentilla recta, Platanthera chlorantha, Agrostemma githago, Prunella grandiflora, Populus alba, Silene tatarica, Papaver argemone, Papaver rhoeas, Veronica polita, Hieracium floribundum, Bromus secalinus, Polygonum bistorta, Geum alleppicu, Astragalus arenarius, Centaurium erythraea, Veronica agrestis, Veronica verna, Cirsium rivulare. Allium oleraceum, Hierochloë odorata, Chenopodium polyspermum, Vinca minor, Dipsacus silvestris and Campanula latifolia.

This present paper, focused on root crop communities of light soils, is a part of the wide range characteristics of segetal communities of the Podlaski Przełom Bugu (Podlasie Bug River Gorge) mesoregion. On the basis of 160 phytosociological relevés made according to the Braun-Blanquet method, phytocenoses representing the Panico-Setarion alliance were distinguished. Most often, patches of the association Echinochloo-Setarietum were recorded in the study area. Heterogeneous habitat conditions affect its floristic diversity. Two subassociations of the phytocenosis, divided according to the species composition into 9 lower syntaxa, were identified on light soils. The following subassociations were distinguished: Echinochloo-Setarietum setarietosum glaucae in a typical variant and a variant with Juncus bufonius, both with subvariants with Digitaria ischaemum, as well as a typical variant of Echinochloo-Setarietum typicum, a variant with Juncus bufonius and a subvariant with Oxalis stricta in the typical and wet variant. Another association found in root crops on light soils of the Podlaski Przełom Bugu mesoregion is Digitarietum ischaemi. Its patches were observed in cultivations on light, acidic, poor soils. The characteristic feature of this community is the occurrence of numerous acidophilous species. In habitat conditions typical for the Podlaski Przełom Bugu mesoregion, Digitarietum ischaemi is differentiated into the typical and wet variant. Quite frequent patches of the Setaria pumila-Setaria viridis community were noted in intermediate habitat conditions, between those characteristic for Digitarietum ischaemi and Echinochloo-Setarietum.
