The results of a long-term experiment (2014-2020) on the creation of a natural meadow-steppe plant community and an assessment of the weed and meadow-steppe plant productivity dynamics in the long-term experiment taken place in the forest-steppe zone of Kuzbass are presented. The preparation of banks consisted in their levelling, and then applying 10 cm fertile soil layer (FSL) and potentially fertile rocks (PFR) represented by loess-like loams. A horizontal section of the bank without application of FSL and PFR was used as a reference. An herb-seed mixture (HSM) was harvested in meadow-steppe areas of hills covered with meadow-steppe vegetation. The highest productivity was obtained in areas with PFR application (555.2 g / m2 in 2017); the share of ruderal plants was 6-25% of the total biomass. Application of FSL for four years leads to the intensive development of Elytrigia repens; by the sixth year, Allium nutans and Artemisia frigida become dominants of the nature-like plant community. In the reference areas, a pioneering group of legumes Oxitropis pilosa and O. campanulata is formed. Areas without the introduction of HSM are at the pioneer and group-overgrown stage of syngenesis.
