Zróżnicowanie zbiorowisk segetalnych jako wyraz luarunków siedliskowych i poziomu kultury rolnej wsi Oleśnik (woj. Piotrków Tryb.) [Differentiation of vegetal communities as an expression of habitat conditions and agriculture standard of the village Oleśnik (Piotrków Tryb. District)]

Abstract

The paper is an analytical description of the differentiation of acidophilic segetal communities of the village Oleśnik (Piotrków Tryb. District) against the background of habitat conditions and standard of agriculture (Tables 3-13, Figs. 3-6). The present segetal vegetation reflects the natural conditions and the state of agricultural management of the agricultural acreage of the village (Figs. 1, 2). It is also an index of the productive passibilities of habitats with the poorest sandy soil. Therefore it may be useful for their evaluation (Table 16). The number, spread and distribution of the distinguished communities are evidence of the phytosociological-ecological nonhomogeneity and indicate the agricultural standard in the given area.
