Associations and communities of cereal crops of the Łuków Plain. Part I. Light soil associations

The characteristics of phytocenoses developing on light soils in cereal crops of the Łuków Plain are presented in the paper. The studies were carried out between 2003 and 2006 in 182 localities. Cereal crops on light soils were frequently occupied by patches of Arnoserido-Scleranthetum. The association reaches the eastern limit of its geographic range in the mesoregion. The phytocenoses were noted under various moisture conditions and were the floristically poorest cereal communities in the studied area. The paper presents new data on the occurrence of Arnoserido-Scleranthetum on its eastern distributional limits. Quite frequently, the patches of Vicietum tetraspermae scleranthetosum, especially of its variant with Juncus bufonius and Vicietum tetraspermae typicum variant with Rhinanthus serotinus, were also frequently noted in the studied mesoregion.Small patches of Papaveretum argemones were recorded very seldom.
