Segetal complex-pioneer stages of syntrophic communities in the Meshchovskiy Opole of the non-Chernozem Zone of Russia

In the conditions placor soil Meshchovskiy Opole the Central economic region of the Nonchernozem zone of the Russian Federation on agro-gray forest middle loamy soils defined by the main species composition of segetal complex field agrophytocenoses in the structure of five fields grain and grain-grass crop rotation in the limit of syntaxon Stellarietea mediae R. Tx. et al. ex von Rochow 1951. The combinations of weed and field species specific to field crops are established and the influence of minimization of basic tillage is shown, including No-till, and applying calculated norms of mineral fertilizers (NPK) on the dynamics of the species composition and number of the main components of the segetal complex is shown. The original synanthropic plant communities on the fallow lands of Meshchovsky Opole develop from the segetal complex of previous agrophytocenoses. The core of the cenoflora is represented by 104 species of higher herbage plants from 29 families. Synanthropic communities have a low species saturation-8 species per 100 m2 and a projection coverage of 57.6%. In acesite territories the advantage is given to the types of anemochory edificatory. Phytomass of secondary phytocenoses without comprehensive measures to improve their floristic composition cannot be used for bulk feed production © The Authors, published by EDP Sciences, 2020.
