Arable lands occupy about 30 percent of the area of the Załęcze Nature Park. Segetal weed associations in cereal plantations and in root crops were studied, and there were distinguished 6 associations, 3 communities, and several phytosociological units of lower rank. From geographical and ecological points of view, the presence of Arnoserido-Scleranthetum and Lamio-Veronicetum politae is of great significance here. Among species of weeds rare in this part of Poland are: Sherardia arvensis, Stachys annua, Bromus secalinus and others (for summary see page 565-566).
